[Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-31711 Summary of the Invention [Problem to be solved by the invention]
[0005] When train operations are restricted in accordance with operational restrictions, changes will occur to the previously planned train schedule. The creation of a revised schedule after the issuance of operational restrictions is usually performed manually. For example, a user such as a dispatcher manually inputs the details of the schedule changes for each train or for each operational rescheduling item into a device such as a train schedule rescheduling terminal, thereby creating the revised schedule. For this reason, it is desirable to be able to reduce the workload on users when creating a revised schedule after the issuance of operational restrictions.
[0006] The present disclosure has been made in consideration of the above, and aims to provide an operation management device that can reduce the workload on a user when creating a revised timetable after operation restrictions are issued. [Means for solving the problem]
[0007] In order to solve the above-mentioned problems and achieve the objectives, the operation management device disclosed herein comprises an information acquisition unit that acquires observation data indicating the status of the line using a detection device mounted on a train, a restriction information creation unit that creates train operation restriction information based on the observation data, a timetable prediction unit that predicts a predicted timetable for trains to which operation restrictions are applied based on the operation restriction information, and a timetable change processing unit that reflects the changed timetable created based on operation rescheduling information when the predicted timetable is applied into the planned timetable. [Effects of the Invention]
[0008] The operation management device according to the present disclosure has the effect of reducing the workload of a user when creating a revised timetable after operation restrictions are issued. [Brief explanation of the drawings]

[0010] Hereinafter, a traffic management device, a traffic management system, a traffic management method, and a traffic management program according to embodiments will be described in detail with reference to the accompanying drawings.
[0011] Embodiment 1 FIG. 1 is a diagram showing an example of the configuration of a railway system including a traffic control system 1 according to a first embodiment. The railway system has a traffic control system 1 and a plurality of trains. The traffic control system 1 is a system that manages the operation of each of the plurality of trains. The traffic control system 1 includes a traffic control device 2, a traffic rescheduling terminal 3, and ground equipment 4.
[0012] In the example shown in Figure 1, each train runs on a line that spans its own line section and another line section. The own line section is a line section where a railway operator that manages trains using the traffic control system 1 operates a railway business. The own line section can also be said to be a line section where traffic control is performed by the traffic control system 1. The other line section is a line section where a railway operator other than the railway operator that manages trains using the traffic control system 1 operates a railway business. The other line section is a line section other than the own line section. Hereinafter, the own company refers to the railway operator that operates the railway business on the own line section. The other company refers to the railway operator that operates the railway business on the other line section.
[0013] Trains 6A, 6B, and 6C shown in Figure 1 are examples of trains owned by the same company. Train 6X shown in Figure 1 is an example of a train owned by another company. In the example shown in Figure 1, trains 6A and 6B are running on the same line. Train 6C is running on another line by direct operation from the same line to another line. Train 6X is running on the same line by direct operation from another line to the same line. Each of trains 6A, 6B, 6C, and 6X shown in Figure 1 is running in the direction of travel indicated by the white arrow.
[0014] Each of the trains 6A, 6B, and 6C is equipped with a detection device 7 that observes the track conditions. The track conditions observed by the detection device 7 may include, for example, the condition of the overhead wires. The condition of the overhead wires is the deterioration state of the overhead wires, such as wear of the wires. The track conditions observed by the detection device 7 may also include the presence or absence of fires along the track, the water level under the viaduct, the deterioration state of crossing gates at railroad crossings, etc.
[0015] Here, as an example, it is assumed that three sensors are provided on each of the trains 6A, 6B, and 6C. Each of the three sensors functions as a detection device 7. The three sensors are a sensor for detecting rainfall, a sensor for detecting wind speed, and a sensor for detecting rail temperature. The rail temperature is the temperature of the rails on which each of the trains 6A, 6B, and 6C runs. Note that FIG. 1 schematically shows one of the detection devices 7 mounted on the train 6A, one of the detection devices 7 mounted on the train 6B, and one of the detection devices 7 mounted on the train 6C.
[0016] Each of the trains 6A, 6B, and 6C is equipped with a camera that captures images of the track conditions. This camera also functions as the detection device 7. Each of the trains 6A, 6B, and 6C may be equipped with multiple cameras facing in different directions. The cameras may detect the track conditions exemplified above.
[0017] Each of the trains 6A, 6B, and 6C is equipped with a communication device that communicates with the traffic management device 2. The communication device is not shown in the figure. The communication device transmits data to the traffic management device 2 by wireless communication via a wireless base station of a mobile communication network included in the network. The network is, for example, a VPN (Virtual Private Network). The communication device periodically transmits observation data to the traffic management device 2, including detection results from each of the three sensors and image data representing images captured by the camera. The communication device transmits at least one of location data indicating the location where the observation data was observed and location data indicating the location where the image was captured, together with the observation data, to the traffic management device 2.
[0018] The communication devices of the trains 6A, 6B, and 6C also communicate with the ground equipment 4. A communication device is also installed on the train 6X, which runs on the same line as the train 6A, 6B, and 6C by through operation. The train 6X communicates with the ground equipment 4. The communication devices of the trains 6A, 6B, 6C, and 6X receive operation restriction information transmitted from the ground equipment 4. The operation restriction information is information indicating operation restrictions.
[0019] In the example shown in Fig. 1, the traffic control system 1 is installed in a central control center together with a control terminal 5. The control terminal 5 displays the operation status of each train running on the line, the status of signals installed on the line, etc. A dispatcher at the central control center monitors the operation status of each train by checking the display on the control terminal 5, and issues instructions to the crew of each train or station staff.
[0020] The traffic management device 2, the traffic control terminal 3, and the ground equipment 4 are connected to each other so that they can communicate with each other. The traffic management device 2 manages the operation of each of the multiple trains. The traffic management device 2 receives observation data and position data, which are data transmitted from the communication devices of each of the trains 6A, 6B, and 6C.
[0021] The train rescheduling terminal 3 receives the planned timetable transmitted from the operation management device 2 and displays the received planned timetable. The train rescheduling terminal 3 accepts operations to change the planned timetable when train rescheduling is performed, such as changing a departure time or changing the operating order of two or more trains.
[0022] The ground equipment 4 functions as an interface for sending information to each of a plurality of trains running on the line. For example, an Automatic Train Operation (ATO) device may function as the ground equipment 4. The ground equipment 4 transmits operation restriction information to trains that are subject to operation restrictions. In FIG. 1, when the trains that are subject to operation restrictions are train 6B and train 6X, the ground equipment 4 transmits operation restriction information to each of train 6B and train 6X.
[0023] The external organization 8 is an organization external to the railway system. Examples of the external organization 8 are organizations that provide weather information, such as the Japan Meteorological Agency or private weather service providers. The traffic control device 2 acquires weather information from the external organization 8 via a network. The network is, for example, a WAN (Wide Area Network) such as the Internet.
[0024] The other line section system 9 is a traffic control system of another company. The traffic control device 2 communicates with the other line section system 9 via a network such as a VPN. The traffic control device 2 transmits traffic rescheduling proposal information to the other line section system 9 via communication via the network. The traffic rescheduling proposal information will be described later.
[0025] Next, we will explain the traffic management device 2, the traffic rescheduling terminal 3, and the ground equipment 4 that make up the traffic management system 1. Fig. 2 is a diagram showing an example of the configuration of the traffic management device 2, the traffic rescheduling terminal 3, and the ground equipment 4 that make up the traffic management system 1 according to the first embodiment.
[0026] The traffic management device 2 includes an information acquisition unit 11, an image analysis unit 12, a restriction information creation unit 13, a timetable prediction unit 14, a timetable change processing unit 15, an other line section notification unit 16, and a planned timetable management unit 17. The traffic management device 2 includes a memory unit 18 that stores various information.
[0027] The information acquisition unit 11 acquires observation data indicating the status of the line by the detection device 7 mounted on the train. The information acquisition unit 11 acquires position data transmitted from the train along with the observation data. The information acquisition unit 11 stores the acquired observation data together with the position data in the memory unit 18. The information acquisition unit 11 acquires weather information about the area around the line from an external organization 8. The information acquisition unit 11 stores the acquired weather information in the memory unit 18. The memory unit 18 holds a database in which the observation data is stored and a database in which the weather information is stored.
[0028] If the acquired observation data includes image data, the information acquisition unit 11 sends the image data to the image analysis unit 12. The image analysis unit 12 analyzes the image data. The image analysis unit 12 analyzes the image data to detect abnormalities at the location where the image was taken. For example, the image analysis unit 12 analyzes the image data to detect obstacles on the route. The image analysis unit 12 may also detect abnormalities other than obstacles. An abnormality detected by the image analysis unit 12 may be any event that could hinder the normal running of a train. For example, the image analysis unit 12 may also detect abnormal weather.
[0029] When the image analysis unit 12 detects the occurrence of an abnormality, it outputs information indicating the occurrence of the abnormality as the result of analyzing the image data to the storage unit 18. The storage unit 18 stores observation data including the result of analyzing the image data.
[0030] The memory unit 18 stores preset restriction issuance conditions. The restriction issuance conditions are conditions that serve as criteria for determining whether to issue driving restrictions. The restriction information creation unit 13 reads out the restriction issuance conditions stored in the memory unit 18.
[0031] The restriction information creation unit 13 determines to issue operation restrictions when the line conditions indicated in the observation data or weather information satisfy the restriction issuance conditions. When it determines to issue operation restrictions, the restriction information creation unit 13 creates operation restriction information that indicates operation restrictions according to the line conditions. The restriction information creation unit 13 creates train operation restriction information based on the observation data and weather information.
[0032] For example, the restriction issuance conditions include a reference value for rainfall, a reference value for wind speed, and a reference value for rail temperature. When the rainfall indicated in the observation data exceeds the reference value, when the wind speed indicated in the observation data exceeds the reference value, or when the rail temperature indicated in the observation data exceeds the reference value, the restriction information creation unit 13 determines that an operation restriction should be issued.
[0033] For example, if the amount of rainfall exceeds a standard value, the restriction information creation unit 13 predicts the time when the amount of rainfall at the point where the amount of rainfall exceeding the standard value was observed will decrease to a certain value based on the amount of rainfall indicated in the observation data and the weather information. In this case, the time predicted by the restriction information creation unit 13 is the time when the rain situation is estimated to have improved and it is safe to lift the operation restrictions. The restriction information creation unit 13 designates the predicted time as the end of the period for which the operation restrictions are issued. The restriction information creation unit 13 creates operation restriction information that prohibits trains from running through the point until the designated time. Hereinafter, the period for which operation restrictions are issued will be referred to as the restriction period.
[0034] The restriction information creating unit 13 sends the created operation restriction information to the ground equipment 4, the timetable prediction unit 14, and the other line section notification unit 16, respectively.
[0035] The ground device 4 includes a restriction information notification unit 19. The restriction information notification unit 19 receives operation restriction information sent from the traffic management device 2. The restriction information notification unit 19 notifies the received operation restriction information to trains that are subject to operation restrictions.
[0036] The planned timetable is stored in the storage unit 18. The planned timetable management unit 17 saves the planned timetable in the storage unit 18 and reads out the planned timetable from the storage unit 18, thereby managing the planned timetable.
[0037] The planned timetable management unit 17 reads the planned timetable from the storage unit 18 when the planned timetable is sent from the operation management device 2 to the timetable rescheduling terminal 3. The planned timetable management unit 17 sends the read planned timetable to the timetable rescheduling terminal 3.
[0038] The timetable prediction unit 14 predicts the predicted timetable of trains to which operation restrictions are applied based on the operation restriction information. When the timetable prediction unit 14 predicts the predicted timetable, the planned timetable management unit 17 reads the planned timetable from the memory unit 18 and outputs the read planned timetable to the timetable prediction unit 14. The timetable prediction unit 14 also receives input of operation restriction information created by the restriction information creation unit 13. The timetable prediction unit 14 identifies from the planned timetable a portion that will need to be changed if train operation is restricted in accordance with the operation restriction information. The timetable prediction unit 14 predicts the predicted timetable up to the time specified as the end of the restriction period, using the identified portion as the target of prediction. The timetable prediction unit 14 sends the predicted timetable to the train rescheduling terminal 3.
[0039] The timetable replanning terminal 3 includes an update processing unit 20, a timetable replanning information creation unit 21, a display unit 22, an operation unit 23, and a memory unit 24. The update processing unit 20 receives the planned timetable sent from the operation management device 2 to the timetable replanning terminal 3. The update processing unit 20 saves the received planned timetable in the memory unit 24. The memory unit 24 stores the planned timetable.
[0040] The display unit 22 displays on its screen the planned timetable that has been sent from the operation management device 2 to the train rescheduling terminal 3 and received by the update processing unit 20. When displaying the planned timetable on the screen, the update processing unit 20 reads the planned timetable from the memory unit 24 and sends the planned timetable to the display unit 22.
[0041] The timetable information creation unit 21 receives the predicted timetable sent from the operation management device 2 to the timetable rescheduling terminal 3. The timetable information creation unit 21 creates timetable rescheduling information based on the predicted timetable predicted by the timetable prediction unit 14 based on the operation restriction information. The timetable rescheduling information is information that indicates the content of timetable rescheduling when a planned timetable that has been planned in advance is changed to a predicted timetable predicted based on the operation restriction information. The timetable information creation unit 21 outputs the created timetable rescheduling information to the display unit 22.
[0042] The display unit 22 displays the timetable replanning information on a screen. The display unit 22 outputs the timetable replanning information created by the timetable replanning information creation unit 21. The display unit 22 notifies the timetable replanning information to users of the traffic management system 1, such as a dispatcher, by displaying the timetable replanning information on a screen. Note that although the display unit 22 is provided inside the timetable replanning terminal 3 in FIG. 2, the display unit 22 may be provided outside the timetable replanning terminal 3.
[0043] The operation unit 23 accepts operations by the user on the timetable replanning terminal 3. The operation unit 23 accepts a selection of approval or denial for the timetable replanning shown in the timetable replanning information output by the display unit 22. The user checks the timetable replanning information displayed on the screen and selects whether to approve or deny the timetable replanning by operating the operation unit 23. Information indicating the user's selection of approval or denial is input to the timetable replanning information creation unit 21. Note that although the operation unit 23 is provided within the timetable replanning terminal 3 in FIG. 2, the operation unit 23 may be provided outside the timetable replanning terminal 3.
[0044] If the timetable rescheduling indicated in the timetable rescheduling information is approved, the timetable rescheduling information creation unit 21 sends the timetable rescheduling information to the operation management device 2. On the other hand, if the timetable rescheduling indicated in the timetable rescheduling information is rejected, the timetable rescheduling information creation unit 21 does not send the timetable rescheduling information to the operation management device 2.
[0045] If the timetable rescheduling indicated in the timetable rescheduling information is approved, the timetable change processing unit 15 receives the timetable rescheduling information sent from the timetable rescheduling terminal 3. The timetable change processing unit 15 creates a revised timetable based on the received timetable rescheduling information. The timetable change processing unit 15 reflects the created revised timetable in the planned timetable of the operation management device 2. In this way, the timetable change processing unit 15 obtains timetable rescheduling information when a predicted timetable is applied, and reflects the revised timetable created based on the timetable rescheduling information in the planned timetable.
[0046] The timetable change processing unit 15 outputs the planned timetable that reflects the changed timetable created by the timetable change processing unit 15 to the planned timetable management unit 17. The planned timetable management unit 17 stores the planned timetable input to the planned timetable management unit 17 in the memory unit 18. The planned timetable management unit 17 sends the planned timetable input to the planned timetable management unit 17 to the train rescheduling terminal 3. The update processing unit 20 receives the planned timetable sent to the train rescheduling terminal 3 from the operation management device 2. The update processing unit 20 stores the received planned timetable in the memory unit 24.
[0047] The other line section notification unit 16 receives operation restriction information created by the restriction information creation unit 13. The other line section notification unit 16 reads out observation data and weather information from the storage unit 18. The planned timetable management unit 17 reads out the planned timetable from the storage unit 18 and outputs the read planned timetable to the other line section notification unit 16.
[0048] The other line section notification unit 16 refers to the timetable of the line section whose operation is managed by the other line section system 9 among the planned timetables. Hereinafter, trains on other line sections refer to trains that run on line sections whose operation is managed by the other line section system 9. Based on the operation restriction information, the other line section notification unit 16 predicts the timetable of trains on other line sections when operation restrictions indicated in the operation restriction information are applied.
[0049] The other line section notification unit 16 creates traffic rescheduling proposal information for proposing traffic rescheduling for trains on the other line section based on the predicted train timetable for that other line section. The other line section notification unit 16 sends the created traffic rescheduling proposal information to the other line section system 9. By checking the traffic rescheduling proposal information received by the other line section system 9, a dispatcher or the like who manages operations on the other line section can recognize that traffic rescheduling for trains on that other line section has been proposed and the details of the traffic rescheduling.
[0050] Next, the procedure of operations performed by the traffic control system 1 will be explained. Here, the series of operations performed by the traffic control system 1 will be explained by dividing them into first to fourth operations. The first operation is the operation performed when acquiring observation data and weather information. The second operation is the operation performed when creating and notifying operation restriction information. The third operation is the operation performed when predicting a forecast timetable and presenting operation rescheduling information. The fourth operation is the operation performed when creating and notifying operation rescheduling proposal information.
[0051] 3 is a flowchart showing an example of a first operation by the traffic control system 1 according to Embodiment 1. The traffic control system 1 performs the operations of steps S1-S4 and the operations of steps S5 and S6 in parallel.
[0052] In step S1, the information acquisition unit 11 acquires observation data. The information acquisition unit 11 also acquires location data indicating the location where the observation data was observed. In step S2, the information acquisition unit 11 determines whether the observation data acquired in step S1 includes image data.
[0053] If the observation data includes image data (step S2, Yes), the information acquisition unit 11 sends the image data to the image analysis unit 12. In step S3, the image analysis unit 12 analyzes the image data. Thereafter, the traffic control system 1 proceeds to step S4. On the other hand, if the observation data does not include image data (step S2, No), the traffic control system 1 skips step S3 and proceeds to step S4.
[0054] In step S4, the information acquisition unit 11 stores the observation data in the storage unit 18. The information acquisition unit 11 stores the observation data acquired in step S1 together with the position data in the storage unit 18. If the observation data includes image data, the image analysis unit 12 stores the results of analyzing the image data in the storage unit 18. In this case, the storage unit 18 stores the observation data including the results of analyzing the image data.
[0055] In step S5, the information acquisition unit 11 acquires weather information from the external organization 8. The information acquisition unit 11 acquires weather information for the location indicated in the position data. In step S6, the information acquisition unit 11 stores the weather information acquired in step S5 in the memory unit 18. By completing steps S4 and S6, the traffic control system 1 ends the first operation according to the procedure shown in FIG. 3. Subsequently, the traffic control system 1 proceeds to the second operation.
[0056] 4 is a flowchart showing a second example of operation by the traffic control system 1 according to embodiment 1. In step S11, the restriction information creation unit 13 reads out observation data and weather information from the storage unit 18. The restriction information creation unit 13 also reads out restriction issuance conditions from the storage unit 18.
[0057] In step S12, the restriction information creating unit 13 determines whether or not the route conditions indicated in the observation data and meteorological information read out in step S11 satisfy the restriction issuance conditions.
[0058] If the route conditions satisfy the restriction issuance conditions (step S12, Yes), the restriction information creation unit 13 determines to issue operation restrictions. In step S13, the restriction information creation unit 13 creates operation restriction information indicating operation restrictions according to the route conditions. The restriction information creation unit 13 sends the created operation restriction information to the ground equipment 4. In step S14, the restriction information notification unit 19 notifies the train of the operation restriction information created in step S13. After completing step S14, the traffic control system 1 ends the second operation according to the procedure shown in FIG. 4.
[0059] On the other hand, if the route conditions do not satisfy the restriction issuance conditions (step S12, No), the restriction information creation unit 13 determines not to issue an operation restriction. In this case, the traffic control system 1 skips steps S13 and S14 and ends the second operation according to the procedure shown in Fig. 4. Then, the traffic control system 1 proceeds to the third operation.
[0060] 5 is a flowchart showing a third example of operation by the traffic control system 1 according to Embodiment 1. The operation restriction information created by the restriction information creation unit 13 is input to the timetable prediction unit 14. The timetable prediction unit 14 reads out the planned timetable stored in the memory unit 18 via the planned timetable management unit 17.
[0061] In step S21, the timetable prediction unit 14 predicts a train timetable up to a specified time based on the operation restriction information. The specified time is the time specified as the end of the period during which operation restrictions are issued. The predicted timetable predicted in step S21 is sent to the operation rescheduling terminal 3 and input to the operation rescheduling information creation unit 21.
[0062] In step S22, the timetable information creation unit 21 creates timetable information based on the predicted timetable predicted in step S21. The timetable information created by the timetable information creation unit 21 is input to the display unit 22. In step S23, the display unit 22 displays the timetable information created in step S22.
[0063] While the timetable replanning information is displayed on the display unit 22, the operation unit 23 waits for an operation to select whether to approve or reject the timetable replanning. When the operation unit 23 receives the operation to select whether to approve or reject, the operation unit 23 sends information indicating the selection result of approval or rejection to the timetable replanning information creation unit 21.
[0064] In step S24, the timetable replanning information creation unit 21 determines whether the timetable replanning information displayed in step S23 has been approved. Based on the information sent from the operation unit 23, the timetable replanning information creation unit 21 determines whether the timetable replanning information has been approved.
[0065] If the timetable rescheduling information is approved (step S24, Yes), the approved timetable rescheduling information is sent to the traffic management device 2 and input to the timetable change processing unit 15. In step S25, the timetable change processing unit 15 creates a revised timetable based on the approved timetable rescheduling information. In step S26, the timetable change processing unit 15 reflects the revised timetable created in step S25 in the planned timetable. The planned timetable reflecting the revised timetable is sent to the planned timetable management unit 17. The planned timetable management unit 17 stores the planned timetable reflecting the revised timetable in the memory unit 18. The planned timetable management unit 17 also sends the planned timetable reflecting the revised timetable to the traffic rescheduling terminal 3. The update processing unit 20 receives the planned timetable reflecting the revised timetable and stores the planned timetable reflecting the revised timetable in the memory unit 24. When the planned timetable reflecting the revised timetable is stored in each of the memory unit 18 and the memory unit 24, the traffic management system 1 ends the third operation according to the procedure shown in FIG. 5.
[0066] On the other hand, if the timetable rescheduling information is not approved, i.e., if the timetable rescheduling information is rejected (step S24, No), the timetable rescheduling information is not sent to the traffic management device 2. In this case, the traffic management system 1 skips steps S25 and S26 and ends the third operation according to the procedure shown in Fig. 5. Then, the traffic management system 1 proceeds to the fourth operation.
[0067] 6 is a flowchart showing a fourth example of operation by the traffic control system 1 according to the first embodiment. In step S31, the other line section notification unit 16 acquires operation restriction information created by the restriction information creation unit 13. The other line section notification unit 16 reads out observation data and weather information from the storage unit 18. The other line section notification unit 16 reads out the planned timetable stored in the storage unit 18 via the planned timetable management unit 17.
[0068] In step S32, the other line section notification unit 16 determines whether there are any trains in other line sections that are subject to operation restrictions. If there are no trains that are subject to operation restrictions (step S32, No), the traffic control system 1 ends the fourth operation according to the procedure shown in FIG.
[0069] On the other hand, if there is a train subject to operation restrictions (step S32, Yes), in step S33, the other line section notification unit 16 predicts the train schedule for the other line section up to a specified time, which is the time designated as the end of the period during which operation restrictions are issued.
[0070] In step S34, the other line section notification unit 16 creates timetable rescheduling proposal information for proposing timetable rescheduling for trains in other line sections based on the timetable predicted in step S33. In step S35, the other line section notification unit 16 notifies the other line section system 9 of the timetable rescheduling proposal information. With this, the traffic control system 1 completes the fourth operation according to the procedure shown in FIG.
[0071] In the above, the traffic management system 1 performs the fourth operation after the third operation. The traffic management system 1 can perform the fourth operation at any timing after the operation restriction information is created in step S13 shown in FIG. 4. For example, the traffic management system 1 may perform the fourth operation before the third operation, or may perform the fourth operation in parallel with the third operation. The traffic management system 1 periodically performs the first to fourth operations described above.
[0072] Next, an example of observation data stored in the storage unit 18 will be described. Fig. 7 is a diagram showing an example of observation data stored in the storage unit 18 of the traffic management device 2 of the traffic management system 1 according to embodiment 1. In the observation data shown in Fig. 7, time information is associated with information on the train number, observation point, rainfall, wind speed, rail temperature, and image analysis results.
[0073] The time information indicates the time when the observation data was observed. The train number information indicates the train number of the train on which the observation data was observed. The train number is an identification number assigned to each of multiple trains. The observation point information indicates the point on which the observation data was observed, and corresponds to the location data described above. In Figure 7, "Station A," "Station B," "Station C," and "Station D" are each the names of stations. "Station A," "Station B," "Station C," and "Station D" are all stations on the same line. The rainfall, wind speed, and rail temperature information are values detected by detection device 7 and represent the results of observing the line conditions.
[0074] The information on the image analysis results indicates the results of analyzing the image data by the image analysis unit 12. In the observation data shown in FIG. 7, the information "no abnormality" shown in each row of the image analysis results indicates that no abnormality was detected by analyzing the image data. If an abnormality is detected by analyzing the image data, the information "abnormality present" is stored as the information on the image analysis results.
[0075] Here, it is assumed that four trains are running on the same line. The trains with train numbers "1M," "2M," "3M," and "4M" are the four trains on the same line. Each of the trains with train numbers "1M," "2M," and "4M" is equipped with a sensor for detecting rainfall, a sensor for detecting wind speed, and a sensor for detecting rail temperature. Each sensor is a detection device 7. The memory unit 18 accumulates observation data observed by the detection devices 7 of the three trains. That is, as illustrated in FIG. 7 , the memory unit 18 stores observation data for each of the trains with train numbers "1M," "2M," and "4M." Each of the trains with train numbers "1M," "2M," and "4M" is equipped with a camera, which is the detection device 7. The observation data stored for each of the trains with train numbers "1M," "2M," and "4M" includes information on the results of image analysis.
[0076] It is assumed that the train with train number "3M" is not equipped with a detection device 7. Therefore, no observation data for the train with train number "3M" is stored in the memory unit 18. The traffic management device 2 separately determines the position of the train with train number "3M" using interlocking information. The interlocking information is information sent from the interlocking device to the traffic management system 1. The interlocking device is, for example, a signal or a track circuit.
[0077] In the example shown in Fig. 7, observation data observed on a train is acquired by the information acquisition unit 11 every minute and stored in the storage unit 18. That is, the observation data acquired at one-minute intervals is stored in the storage unit 18. Note that the interval at which the observation data is acquired is not limited to one minute and may be any interval.
[0078] 7, the rainfall values of 15 mm and 16 mm observed by train number "4M" at "Station D" at 14:00, 14:01, and 14:02 on September 22, 2023 exceed the reference rainfall value indicated in the restriction issuance conditions. Since the rainfall at "Station D" satisfies the restriction issuance conditions, the restriction information creation unit 13 decides to issue an operation restriction that restricts train operations at "Station D."
[0079] FIG. 8 is a diagram for explaining an example of operation restrictions issued by the traffic management device 2 of the traffic management system 1 according to the first embodiment. In the following description, each time is assumed to be a time shown in the observation data shown in FIG. 7 and to be a time on September 22, 2023. FIG. 8 shows the positions of five trains at 14:00, 14:01, and 14:02. The observation data shown in FIG. 7 is assumed to be observation data observed by trains with train numbers "1M," "2M," and "4M" shown in FIG. 8. The train with train number "6M" is assumed to be a train on another line. The train with train number "6M" is not equipped with a detection device 7. In the following description, each of the five trains will be represented by its train number.
[0080] "1M" and "3M" are trains heading from "Station A" to "Station D" between 14:00 and 14:02. "2M" and "4M" are trains heading from "Station D" to "Station A" during the same time period. "Station E" is the station one stop after "Station D" and is on a different line.
[0081] As shown in the observation data in FIG. 7, suppose that at 14:00, rainfall exceeding the reference value is detected at "4M" at "Station D." In other words, the situation at "Station D" is such that train operation should be stopped due to rainfall. At the same time, suppose that "4M" is stopped at "Station D." Since rainfall exceeding the reference value has been detected, the restriction information creation unit 13 issues an operation restriction to "4M" to prevent it from departing from "Station D."
[0082] Based on the rainfall conditions at "Station D," the restriction information creation unit 13 issues an operation restriction command to have trains heading toward "Station D" wait at the station. As shown in FIG. 8, at 14:00, "3M" heading toward "Station D" is stopped at "Station A." The restriction information creation unit 13 issues an operation restriction command to "3M" to prevent it from departing from "Station A."
[0083] As shown in FIG. 8, "1M" is heading toward "Station D" and travels between "Station A" and "Station B" at 14:00 and 14:01. "1M" then arrives at "Station B" and stops at "Station B" at 14:02. The restriction information creation unit 13 issues an operational restriction to "1M" to prevent it from departing from "Station B." Note that in FIG. 8, the hatching on "1M," "3M," and "4M" indicates that they are subject to operational restrictions.
[0084] As shown in FIG. 8, "2M" is heading in the opposite direction from "Station D" and is stopped at "Station C" at 14:00. Since "2M" is not a train heading in the direction of "Station D," the restriction information creation unit 13 does not issue an operational restriction to "2M." "2M" operates according to the planned timetable.
[0085] As shown in Fig. 8, "6M" is heading toward "Station D" on another line section and stops at "Station E" at 14:00 and 14:01. Since "6M" is a train on another line section, the restriction information creation unit 13 does not issue an operation restriction for "6M."
[0086] The timetable prediction unit 14 predicts the predicted timetables for "1M," "3M," and "4M," trains on the same line that are subject to operation restrictions, based on operation restriction information. The timetable information creation unit 21 creates timetable information based on the predicted timetables for "1M," "3M," and "4M." When the timetable rescheduling is approved, the timetable change processing unit 15 creates a revised timetable based on the timetable information and reflects the revised timetable in the planned timetable.
[0087] As described above, "1M" and "4M" are trains equipped with a detection device 7. "3M" is a train not equipped with a detection device 7. The timetable prediction unit 14 predicts the predicted timetable for trains equipped with a detection device 7 and the predicted timetable for trains not equipped with a detection device 7. The timetable change processing unit 15 reflects the changed timetables created based on the timetable rescheduling information for trains equipped with a detection device 7 and trains not equipped with a detection device 7 in the planned timetable. This allows the traffic management device 2 to create a planned timetable that reflects the timetable changes due to timetable rescheduling for both trains equipped with a detection device 7 and trains not equipped with a detection device 7.
[0088] The other line section notification unit 16 predicts the timetable for "6M," a train on another line section, based on operational restriction information. Based on the predicted timetable for "6M," the other line section notification unit 16 creates operational reordering proposal information for proposing operational reordering for "6M." In the example shown in FIG. 8, the other line section notification unit 16 creates operational reordering proposal information for proposing operational reordering to suppress the departure of "6M" from "Station E." The other line section notification unit 16 sends the created operational reordering proposal information to the other line section system 9. As a result, the other line section notification unit 16 proposes to the other line section system 9 operational reordering to suppress the departure of "6M" from "Station E." In FIG. 8, the hatching next to "6M" indicates that it has been subject to a proposed operational reordering. The other line section notification unit 16 may also send only operational restriction information, which does not include information about a timetable predicted based on operational restriction information, to the other line section system 9 as operational reordering proposal information.
[0089] FIG. 9 is a diagram showing an example of a planned timetable stored in the storage unit 18 of the traffic management device 2 of the traffic management system 1 according to the first embodiment. FIG. 9 shows examples of planned timetables for "1M," "2M," "3M," and "4M" shown in FIG. 8. The planned timetable shown in FIG. 9 is the planned timetable before changes to the timetable based on traffic rescheduling are reflected. In FIG. 9, the planned timetable is represented by a broken solid line.
[0090] According to the planned timetable shown in Figure 9, "4M" will arrive at "Station A" after "2M" and depart from "Station A" before "2M". In other words, "2M" will be overtaken by "4M". The area enclosed by a box 31 in Figure 9 indicates that this overtaking will take place.
[0091] Fig. 10 is a diagram showing an example of a predicted timetable predicted by the timetable prediction unit 14 included in the traffic management device 2 of the traffic management system 1 according to the first embodiment. In Fig. 10, the planned timetable is represented by a solid polygonal line. The part of the planned timetable that is the subject of prediction is represented by a dashed polygonal line. The predicted timetable is represented by a dashed polygonal line.
[0092] The area 33 shown in FIG. 10 represents the location subject to the operation restriction and the restriction period during which the operation restriction is issued. The location subject to the operation restriction is "Station D," where a situation satisfying the conditions for issuing the restriction was observed. The restriction period begins at 14:00, when rainfall exceeding the restriction value was first observed at "Station D." The time designated as the end of the restriction period is 15:00. The timetable prediction unit 14 predicts the predicted timetables for "1M," "3M," and "4M" in the area 33 based on the operation restriction information.
[0093] The timetable prediction unit 14 predicts a timetable for "1M" that will stop at "Station B" from 14:00 to 15:00, which is a restriction period, and then head towards "Station D" with delays from the planned timetable. The timetable prediction unit 14 predicts a timetable for "3M" that will stop at "Station A" from 14:00 to 15:00, which is a restriction period, and then head towards "Station D" with delays from the planned timetable. The timetable prediction unit 14 predicts a timetable for "4M" that will stop at "Station D" from 14:00 to 15:00, which is a restriction period, and then head towards "Station A" with delays from the planned timetable.
[0094] As such, "4M" is predicted to be delayed from the planned timetable, while "2M" is predicted to operate according to the planned timetable. In the planned timetable, "4M" was supposed to overtake "2M" at "Station A," but due to the delay of "4M," this overtaking will be canceled. The area enclosed by box 32 in Figure 10 indicates that this overtaking will be canceled. In other words, the order in which the two trains, "2M" and "4M," depart from "Station A" is "4M" followed by "2M" in the planned timetable, but will change to "2M" followed by "4M" in the predicted timetable.
[0095] FIG. 11 is a diagram showing an example of traffic rescheduling information displayed on the traffic rescheduling terminal 3 of the traffic management system 1 according to the first embodiment. The "Automatic Traffic Rescheduling Proposal" screen shown in FIG. 11 is a screen displayed on the display unit 22, on which traffic rescheduling information is displayed. The traffic rescheduling terminal 3 notifies the user of the traffic rescheduling information through this screen, and accepts the user's choice of approving or rejecting the traffic rescheduling. The "Automatic Traffic Rescheduling Proposal" screen displays the text "Due to rainfall restrictions issued at Station D," indicating that rainfall exceeding the standard value was observed at Station D, as the reason for the traffic rescheduling.
[0096] The timetable information creation unit 21 creates timetable information based on the predicted timetable as shown in FIG. 10. For "1M", timetable information is created indicating that the departure from "Station B" will be changed to 15:00. For "3M", timetable information is created indicating that the departure from "Station A" will be changed to 15:00. For "4M", timetable information is created indicating that the departure from "Station D" will be changed to 15:00. Furthermore, for "4M", timetable information is created indicating that the departure from "Station A" will be changed to after "2M". In this way, the timetable information creation unit 21 creates four pieces of timetable information based on the predicted timetable as shown in FIG. 10.
[0097] As shown in Figure 11, the "Automatic Train Replanning Proposal" screen lists text representing the content of each of the four pieces of train replanning information. For example, "1M Departure time change B Station 15:00" represents the content of the train replanning information for "1M."
[0098] The "Automatic timetable rescheduling proposal" screen displays the buttons "Details," "Approve," and "Reject" for each of the four pieces of timetable rescheduling information. When the "Details" button is pressed, the display unit 22 displays a screen showing the details of the timetable rescheduling. Pressing the "Details" button displays the planned timetable and predicted timetable, for example, as shown in FIG. 10. Note that the content displayed when the "Details" button is pressed is not limited to that described here, and may be any content related to timetable rescheduling.
[0099] The "Approve" button is a button that accepts the selection of approval for the proposed timetable re-arrangement. The user selects to approve the proposed timetable re-arrangement by clicking the "Approve" button through operation of the operation unit 23. The "Reject" button is a button that accepts the selection of rejection for the proposed timetable re-arrangement. The user selects to reject the proposed timetable re-arrangement by clicking the "Reject" button through operation of the operation unit 23.
[0100] The "Automatic Traffic Reorganization Proposal" screen displays the "Cancel" and "Confirm" buttons. Pressing the "Cancel" button cancels the state in which the "Approve" or "Reject" button has been pressed. Pressing the "Confirm" button confirms the selection of approval by pressing the "Approve" button, or the selection of rejection by pressing the "Reject" button.
[0101] The timetable rescheduling information creation unit 21 sends the timetable rescheduling information for which approval has been selected on the "Automatic timetable rescheduling proposal" screen to the operation management device 2. The timetable change processing unit 15 creates a revised timetable based on the timetable rescheduling information for which approval has been selected on the "Automatic timetable rescheduling proposal" screen. The timetable change processing unit 15 reflects the created revised timetable in the planned timetable. In this way, the operation management device 2 creates a planned timetable that reflects the changed timetable based on the timetable rescheduling information.
[0102] FIG. 12 is a diagram illustrating another example of operation restrictions issued by the operation management device 2 of the operation management system 1 according to the first embodiment. The example shown in FIG. 12 is a case where an obstacle is detected on the route between "Station B" and "Station C" at 10:00, and information indicating "abnormality detected" is stored as information on the image analysis result. One of the conditions for issuing a restriction is assumed to include a condition that the image analysis result indicates "abnormality detected." The restriction information creation unit 13 determines the issuance of an operation restriction that restricts train operations between "Station B" and "Station C" until the cause of the abnormality is resolved.
[0103] In the example shown in FIG. 12, the control information creation unit 13 issues an operation restriction to "1M," which has detected an obstacle, to stop the train before the obstacle. "2M," "3M," and "4M" are each trains heading toward the obstacle. The control information creation unit 13 issues an operation restriction to "2M," which is stopped at "D Station," to prevent it from departing from "D Station." The control information creation unit 13 issues an operation restriction to "3M," which is stopped at "A Station," to prevent it from departing from "A Station." Note that in FIG. 12, the hatching on each of "1M," "2M," and "3M" indicates that they are subject to operation restrictions.
[0104] In the example shown in FIG. 12, "4M" is a train on another line section that is stopped at "Station E" on that line section. The other line section notification unit 16 predicts the timetable for "4M" based on operational restriction information. Based on the predicted timetable for "4M," the other line section notification unit 16 creates operational rescheduling proposal information for proposing operational rescheduling to prevent the departure of "4M" from "Station E." The other line section notification unit 16 sends the created operational rescheduling proposal information to the other line section system 9. As a result, the other line section notification unit 16 proposes to the other line section system 9 a operational rescheduling to prevent the departure of "4M" from "Station E." In FIG. 12, the hatching around "4M" indicates that it has been subject to a proposed operational rescheduling.
[0105] In the above description, the sensor mounted on the train as the detection device 7 is a sensor that detects rainfall, wind speed, or rail temperature. However, the sensor mounted on the train as the detection device 7 is not limited to these sensors. Any sensor capable of observing the track conditions may be used. The observation data stored in the memory unit 18 is not limited to those that include the values of rainfall, wind speed, and rail temperature. The observation data stored in the memory unit 18 does not have to include at least one of the values of rainfall, wind speed, and rail temperature. Alternatively, the observation data stored in the memory unit 18 may include values other than the values of rainfall, wind speed, and rail temperature.
[0106] In the above description, a camera serving as the detection device 7 is mounted on the train, but the camera serving as the detection device 7 does not have to be mounted on the train. In this case, the traffic management device 2 may omit the image analysis unit 12. The observation data stored in the memory unit 18 does not have to include information on the image analysis results.
[0107] In the above description, the detection device 7 installed on trains owned by the company observes the track conditions in the company's own line section. For trains owned by the company that enter other line sections, the detection device 7 may also observe the track conditions in the other line section. In this case, the information acquisition unit 11 acquires observation data indicating the results of detection of the track conditions in the other line section by the detection device 7 installed on trains that enter other line sections from the company's own line section. The restriction information creation unit 13 creates operation restriction information according to the track conditions in the other line section. The timetable prediction unit 14 predicts the timetable for trains entering other line sections based on the operation restriction information. The timetable change processing unit 15 reflects the changed timetable based on the operation rescheduling information for trains entering other line sections in the planned timetable. This allows the traffic management device 2 to create a planned timetable for trains entering other line sections that reflects timetable changes due to operation rescheduling.
[0108] Next, a description will be given of a hardware configuration that realizes the traffic management device 2. Fig. 13 is a diagram showing an example of a hardware configuration that realizes the traffic management device 2 according to the first embodiment. The traffic management device 2 is realized by a computer system including a processing circuit 41 and a communication device 42. The processing circuit 41 includes a processor 43 and a memory 44. The processing circuit 41 is a circuit on which the processor 43 executes software.
[0109] The processing functions of each of the information acquisition unit 11, image analysis unit 12, restriction information creation unit 13, timetable prediction unit 14, timetable change processing unit 15, other line section notification unit 16, and planned timetable management unit 17 shown in FIG. 2 are realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in memory 44. In the processing circuit 41, the processor 43 reads and executes the program stored in memory 44, thereby realizing the processing functions of the traffic management device 2. In other words, the processing circuit 41 includes memory 44 for storing a traffic management program, which is a program that results in the processing of the traffic management device 2. In addition, the traffic management program stored in memory 44 can also be said to cause a computer to execute the procedures and methods of the traffic management device 2.
[0110] The processor 43 is a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, a processor, or a DSP (Digital Signal Processor). The memory 44 is, for example, a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD (Digital Versatile Disc). The storage unit 18 shown in FIG. 2 is realized by using the memory 44.
[0111] The communication device 42 communicates with devices external to the traffic management device 2. The communication function of the traffic management device 2 is realized by using the communication device 42. Note that the traffic management device 2 may include an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).
[0112] Next, a description will be given of the hardware configuration that realizes the timetable replanning terminal 3. Fig. 14 is a diagram showing an example of the hardware configuration that realizes the timetable replanning terminal 3 according to the first embodiment. The timetable replanning terminal 3 is realized by a computer system that includes a processing circuit 51, a communication device 52, an input device 55, and a display device 56. The processing circuit 51 includes a processor 53 and a memory 54. The processing circuit 51 is a circuit on which the processor 53 executes software.
[0113] The processing functions of the update processing unit 20 and the timetable replanning information creation unit 21 shown in FIG. 2 are realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in memory 54. In the processing circuit 51, the processor 53 reads and executes the program stored in memory 54, thereby realizing the processing functions of the timetable replanning terminal 3. That is, the processing circuit 51 includes memory 54 for storing a program that results in the processing of the timetable replanning terminal 3. The program stored in memory 54 can also be said to cause a computer to execute the procedures and methods of the timetable replanning terminal 3. The processor 53 and memory 54 will be described in the same manner as the processor 43 and memory 44 shown in FIG. 13. The storage unit 24 shown in FIG. 2 is realized using the memory 54.
[0114] The communication device 52 communicates with devices external to the traffic reconciliation terminal 3. The communication function of the traffic reconciliation terminal 3 is realized by using the communication device 52. The input device 55 is a device that is operated by a user of the traffic reconciliation terminal 3, and into which information is input. The input device 55 includes, for example, a keyboard, a mouse, a keypad, or a touch panel. The display device 56 is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display. The function of the operation unit 23 shown in FIG. 2 is realized by using the input device 55. The function of the display unit 22 shown in FIG. 2 is realized by using the display device 56. The traffic reconciliation terminal 3 may include an integrated circuit such as an ASIC or FPGA.
[0115] The hardware configuration realizing the ground equipment 4 is assumed to be the same as the hardware configuration shown in Fig. 13. The processing function of the regulation information notification unit 19 shown in Fig. 2 is realized by the processor 43 reading and executing a program stored in the memory 44, as in the case of the traffic management device 2. The communication function of the ground equipment 4 is realized by using the communication device 42, as in the case of the traffic management device 2. Note that the ground equipment 4 may include an integrated circuit such as an ASIC or an FPGA.
[0116] According to the first embodiment, the traffic management device 2 includes an information acquisition unit 11 that acquires observation data, a restriction information creation unit 13 that creates train operation restriction information based on the observation data, a timetable prediction unit 14 that predicts a predicted timetable for trains to which operation restrictions are applied based on the operation restriction information, and a timetable change processing unit 15 that reflects a modified timetable created based on operation reordering information when the predicted timetable is applied into a planned timetable. The traffic management device 2 acquires the operation reordering information and reflects the modified timetable created based on the operation reordering information into the planned timetable, thereby eliminating the need for a user to manually create a timetable after a change due to an operation restriction. This allows the traffic management device 2 to reduce the workload on the user when creating a modified timetable after an operation restriction is issued.
[0117] The information acquisition unit 11 also acquires weather information from the external organization 8. The restriction information creation unit 13 creates operation restriction information based on the observation data and the weather information. This allows the operation management device 2 to predict a change in timetable when operation restrictions are applied, taking into account the weather information provided by the external organization 8.
[0118] The observation data acquired by the information acquisition unit 11 also includes image data of the route conditions. The restriction information creation unit 13 creates driving restriction information based on the observation data including the results of analyzing the image data. This allows the traffic management device 2 to issue driving restrictions when there is an abnormality detectable from the image.
[0119] Furthermore, the timetable prediction unit 14 predicts the predicted timetables for trains equipped with the detection device 7 and trains not equipped with the detection device 7. The timetable change processing unit 15 reflects the changed timetables for trains equipped with the detection device 7 and trains not equipped with the detection device 7 in the planned timetable. This allows the traffic management device 2 to create a planned timetable that reflects the timetable changes due to operational rescheduling for both trains equipped with the detection device 7 and trains not equipped with the detection device 7.
[0120] The traffic management device 2 also includes an other line section notification unit 16 that notifies the other line section system 9 of traffic rescheduling proposal information for proposing traffic rescheduling for trains whose operations are managed by the other line section system 9. In this way, the traffic management device 2 can make a dispatcher or the like who manages the operations of the other line section aware that a traffic rescheduling for trains on the other line section has been proposed and the details of the traffic rescheduling.
[0121] The information acquisition unit 11 also acquires observation data indicating the status of the line in the other line section from a detection device 7 mounted on a train entering from the current line section to the other line section. The restriction information creation unit 13 creates operation restriction information based on the observation data including the status of the line in the other line section. The timetable prediction unit 14 predicts a predicted timetable for trains entering the other line section based on the operation restriction information. The timetable change processing unit 15 reflects the changed timetable created based on the operation rescheduling information for trains entering the other line section into the planned timetable. This allows the traffic management device 2 to create a planned timetable for trains entering the other line section that reflects timetable changes due to operation rescheduling.
[0122] According to the first embodiment, the traffic management system 1 includes a traffic management device 2 and a traffic rescheduling terminal 3. The traffic rescheduling terminal 3 has a traffic rescheduling information creation unit 21 that creates traffic rescheduling information based on a predicted timetable. The traffic management system 1 creates traffic rescheduling information using the traffic rescheduling terminal 3 and reflects the changed timetable created based on the traffic rescheduling information in the planned timetable, thereby eliminating the need for the user to manually create a timetable after changes due to traffic restrictions. This allows the traffic management system 1 to reduce the workload on the user when creating a timetable after changes due to traffic restrictions.
[0123] The timetable replanning terminal 3 also has a display unit 22 that outputs timetable replanning information created by the timetable replanning information creation unit 21, and an operation unit 23 that accepts a selection of approval or rejection for the timetable replanning indicated in the output timetable replanning information. The timetable change processing unit 15 acquires timetable replanning information for which approval of the timetable replanning has been selected. This allows the traffic management system 1 to create a timetable after changes due to operational restrictions based on the timetable replanning that has been approved by the user.
[0124] The traffic control system 1 also includes ground equipment 4. The ground equipment 4 has a restriction information notification unit 19 that notifies trains of operation restriction information. This allows the traffic control system 1 to notify trains of operation restriction information according to the status of the line.
[0125] The configurations described in the above embodiments are examples of the contents of the present disclosure. The configurations of the embodiments can be combined with other known technologies.
