Description

Technical Field

[0001] The invention belongs to the technical field of public transportation, and in particular relates to a system and method for identifying waiting time of public transportation passengers. Background Art

[0002] As traffic planning returns to the concepts of "public transport priority" and "people-oriented transport", informatization, intelligence and sustainable development are the key. In order to optimize the public transport management system, passenger information collection is particularly important, and passenger waiting time data is essential. At present, the data sources of public transport passenger waiting time generally adopt the following two collection methods: manual counting method. The defect of this method is that it requires personnel to be assigned to each station to count the time, the labor cost is too high, the data collection cannot achieve all-weather coverage, and the accuracy rate is low; model prediction method. This method infers the range of passenger waiting time based on correlation data, and its algorithm itself has limitations. Therefore, the accurate collection of passenger waiting time has become an inevitable trend. However, the existing passenger waiting data collection cannot accurately obtain the waiting time data of public transport passengers, so the contribution to public transport research is still lacking.

[0003] Patent CN105469602A discloses a method for predicting the waiting time range of bus passengers based on IC card data. The method can predict that the next bus will arrive at a certain station from a certain time to a certain time, filling the gap in the prediction of the arrival time range of buses. However, the invention obtains the headway time based on IC card data, the data collection is not comprehensive, and the waiting time of passengers who wait for the bus twice is omitted, so the waiting time range obtained is not comprehensive enough. Summary of the invention

[0004] The purpose of the present invention is to provide a system and method for identifying the waiting time of public transport passengers, which are conducive to accurately and reliably obtaining the waiting time of public transport passengers.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a bus passenger waiting time identification system, characterized in that it includes a station information collection device arranged at a bus station, an on-board information collection device arranged on a bus, and a central processing system;

[0006] The station information collection device includes a station panoramic camera, a station pressure sensor, a station control unit and a station wireless communication module. The station panoramic camera is used to detect and shoot images of waiting passengers on the waiting platform. The station pressure sensor is used to detect the weight of waiting passengers on the waiting platform. The station panoramic camera and the station pressure sensor are respectively connected to the station control unit, and wirelessly communicate with the central processing system via the station wireless communication module to upload the information collected at the bus station;

[0007] The vehicle-mounted information collection device includes a vehicle-mounted door opening and closing detector, a vehicle-mounted camera, a vehicle-mounted pressure sensor, a vehicle-mounted GPS locator, a vehicle-mounted control unit and a vehicle-mounted wireless communication module. The vehicle-mounted door opening and closing detector is used to detect the opening and closing of the bus door. The vehicle-mounted camera is used to take images of passengers in the boarding area after the bus door is opened. The vehicle-mounted pressure sensor is used to detect the weight of the passengers boarding the bus. The vehicle-mounted GPS locator is used to obtain GPS information of the bus. The vehicle-mounted door opening and closing detector, the vehicle-mounted camera, the vehicle-mounted pressure sensor, and the vehicle-mounted GPS locator are respectively connected to the vehicle-mounted control unit, and wirelessly communicate with the central processing system via the vehicle-mounted wireless communication module to upload the information collected on the bus;

[0008] The central processing system is used to identify the waiting time of passengers based on the information collected by the station information collection device and the vehicle-mounted information collection device.

[0009] Furthermore, the shooting direction of the station panoramic camera is toward the waiting platform to capture images of waiting passengers on the waiting platform; the station pressure sensor is installed on the ground of the waiting platform pressure sensing area to detect the weight of waiting passengers on the waiting platform.

[0010] Furthermore, the on-board door opening and closing detector is installed on the bus door to detect the opening and closing of the bus door; the shooting direction of the on-board camera is toward the boarding area to capture the image of passengers in the boarding area after the bus door is opened; the on-board pressure sensor is installed on the ground of the boarding area to detect the weight of the passengers boarding the bus.

[0011] The present invention also provides a method for identifying the waiting time of public transport passengers, comprising the following steps:

[0012] When waiting passengers step onto the waiting platform, they generate pressure. The station control unit records the start time of waiting. The station pressure sensor collects platform gravity data. The station panoramic camera takes images of waiting passengers. The station control unit uploads relevant information including the start time of waiting, platform gravity data, and images of waiting passengers to the central processing system. The central processing system extracts the characteristic attributes of waiting passengers through image recognition and numbers them, and then stores the characteristics of the passengers and the start time of waiting.

[0013] When the bus arrives at the station and the door opens, the on-board door opening and closing detector detects that the door is opened, and the on-board pressure sensor collects gravity data on the bus, the on-board camera captures the image of the boarding passenger, and the on-board control unit records the boarding time. The on-board control unit uploads the relevant information including the boarding time, gravity data on the bus, the image of the boarding passenger, and the GPS information of the bus to the central processing system; the central processing system extracts the characteristic attributes of the boarding passenger through image recognition and numbers them, and then stores the passenger characteristics and boarding time;

[0014] The central processing system matches the locations of different bus stops with the GPS information of the bus, and then matches the matching waiting platforms with the passenger characteristics of the bus, and subtracts the matching passenger's boarding time from the starting waiting time to obtain the passenger's waiting time data.

[0015] Furthermore, the central processing system divides passengers into waiting passengers, non-waiting passengers and lost passengers; for passengers who get on the bus, if the characteristic attributes of the boarding passengers match the characteristic attributes of the waiting passengers, the passenger is judged to be a waiting passenger, that is, a passenger who gets on the bus after waiting; for passengers who get on the bus, if the characteristic attributes of the boarding passengers cannot match the corresponding characteristic attributes of the waiting passengers, the passenger is judged to be a non-waiting passenger, that is, a passenger who arrives at the bus stop as soon as the bus arrives and can get on the bus without waiting; for the station information collection device records the characteristic attributes of the waiting passengers, but there is no matching characteristic attributes of the boarding passengers within the set time, the passenger is judged to be a lost passenger, that is, a passenger who gives up waiting and leaves the bus stop after waiting.

[0016] Furthermore, the site pressure sensor continuously detects the total weight on the pressure sensing area. When the total weight increases by one human weight level, the site panoramic camera is triggered to capture images of waiting passengers, and the relevant information is uploaded to the central processing system through the site control unit. The central processing system extracts the characteristic attributes of waiting passengers through image recognition, compares them with the recorded characteristic attributes of waiting passengers, and determines whether the passenger is standing on the platform for the first time within the time period. If so, the system records and stores the information with a number.

[0017] Furthermore, when a passenger walks down the pressure sensing area of ​​the waiting platform, the station pressure sensor detects a decrease in the total weight on the pressure sensing area and filters this change; when the passenger walks down the pressure sensing area of ​​the waiting platform and then walks up again, the station panoramic camera takes an image of the waiting passenger and uploads it. The central processing system determines through comparison that this is not the first time the passenger has stepped onto the platform within this time period, and the record is not renumbered and stored.

[0018] Furthermore, after the on-board door opening and closing detector detects that the door is opened, the on-board pressure sensor starts to detect the weight change in the boarding area. When the weight increases by one human weight level, the on-board camera captures the image of the boarding passenger, the on-board control unit records the boarding time, and uploads the relevant information to the central processing system through the on-board control unit; when the on-board door opening and closing detector detects that the door is closed, the on-board camera stops shooting.

[0019] Furthermore, the central processing system uses the door opening time during the working hours of the bus as the time node, queries the GPS information of the bus at the time node, and compares and matches it with the location information of the bus stop, finds the bus stop with a matching location, and calls the passenger arrival timetable of the bus stop. The timetable captures a certain time range before the time when the first passenger gets on the bus, mainly based on the passengers getting on the bus, matches the passenger characteristics, subtracts the boarding time of the same passenger from the starting waiting time, and records it as the waiting time of the passenger, and combines the passenger's number at the bus stop and the number on the bus as its ID for easy reference.

[0020] Compared with the prior art, the present invention has the following beneficial effects: a system and method for identifying the waiting time of bus passengers are provided. The system and method utilize a variety of detection technologies installed at bus stops and on buses to accurately obtain information related to passengers waiting and boarding, and then match passengers through image recognition and matching technologies, thereby automatically, efficiently, accurately and reliably calculating the waiting time of passengers, thus overcoming the problem that the prior art cannot accurately obtain the waiting time of bus passengers, and has strong practicality and broad application prospects.

[0027] like Figure 1As shown, this embodiment provides a system for identifying waiting time for public transportation passengers, including a station information collection device arranged at a public transportation station, a vehicle-mounted information collection device arranged on a bus, and a central processing system.

[0028] The station information collection device includes a station panoramic camera, a station pressure sensor, a station control unit and a station wireless communication module. The station panoramic camera is used to detect and shoot images of waiting passengers on the waiting platform. The station pressure sensor is used to detect the weight of waiting passengers on the waiting platform.

[0029] The vehicle-mounted information collection device includes a vehicle-mounted door opening and closing detector, a vehicle-mounted camera, a vehicle-mounted pressure sensor, a vehicle-mounted GPS locator, a vehicle-mounted control unit and a vehicle-mounted wireless communication module. The vehicle-mounted door opening and closing detector is used to detect the opening and closing of the bus door. The vehicle-mounted camera is used to capture the image of passengers in the boarding area after the bus door is opened. The vehicle-mounted pressure sensor is used to detect the weight of the passengers boarding the bus. The vehicle-mounted GPS locator is used to obtain the GPS information of the bus. The vehicle-mounted door opening and closing detector, the vehicle-mounted camera, the vehicle-mounted pressure sensor, and the vehicle-mounted GPS locator are respectively connected to the vehicle-mounted control unit, and wirelessly communicate with the central processing system via the vehicle-mounted wireless communication module to upload the information collected on the bus.

[0030] The central processing system is used to identify the waiting time of passengers based on the information collected by the station information collection device and the vehicle-mounted information collection device.

[0031] In this embodiment, the shooting direction of the site panoramic camera is toward the waiting platform to capture images of waiting passengers on the waiting platform; the site pressure sensor is installed on the ground of the waiting platform pressure sensing area to detect the weight of waiting passengers on the waiting platform.

[0032] In this embodiment, the on-board door opening and closing detector is installed on the bus door to detect the opening and closing of the bus door; the shooting direction of the on-board camera is toward the boarding area to capture the image of passengers in the boarding area after the bus door is opened; the on-board pressure sensor is installed on the ground of the boarding area to detect the weight of the passengers boarding the bus.

[0033] This embodiment also provides a method for identifying the waiting time of public transportation passengers based on the above system, and its implementation principle is as follows: Figure 2 The method comprises the following steps:

[0034] 1) When waiting passengers step onto the waiting platform, they generate pressure. The station control unit records the start time of waiting. The station pressure sensor collects platform gravity data. The station panoramic camera captures images of waiting passengers. The station control unit uploads relevant information including the start time of waiting, platform gravity data, and images of waiting passengers to the central processing system. The central processing system extracts the characteristic attributes of waiting passengers through image recognition and numbers them, and then stores the characteristics of the passengers and the start time of waiting.

[0035] 2) When the bus arrives at the station and the door is opened, the on-board door opening and closing detector detects that the door is opened, and the on-board pressure sensor collects gravity data on the bus, the on-board camera captures the image of the boarding passenger, and the on-board control unit records the boarding time. The on-board control unit uploads the relevant information including the boarding time, gravity data on the bus, the image of the boarding passenger, and the GPS information of the bus to the central processing system; the central processing system extracts the characteristic attributes of the boarding passenger through image recognition and numbers them, and then stores the passenger characteristics and boarding time;

[0036] 3) The central processing system matches the locations of different bus stops with the GPS information of the bus, and then matches the matching waiting platforms with the passenger characteristics of the bus, and subtracts the matching passenger's boarding time from the starting waiting time to obtain the waiting time data of the passenger.

[0037] In this embodiment, the central processing system divides passengers into waiting passengers, non-waiting passengers and lost passengers; for passengers who get on the bus, if the characteristic attributes of the boarding passengers match the characteristic attributes of the waiting passengers, the passenger is judged to be a waiting passenger, that is, a passenger who gets on the bus after waiting; for passengers who get on the bus, if the characteristic attributes of the boarding passengers cannot match the corresponding characteristic attributes of the waiting passengers, the passenger is judged to be a non-waiting passenger, that is, a passenger who arrives at the bus stop and the bus arrives without waiting; for the station information collection device records the characteristic attributes of the waiting passengers, but there is no matching characteristic attributes of the boarding passengers within the set time, the passenger is judged to be a lost passenger, that is, a passenger who gives up waiting and leaves the bus stop.

[0038] In this embodiment, the site pressure sensor continuously detects the total weight on the pressure sensing area. When the total weight increases by one human weight level, the site panoramic camera is triggered to capture images of waiting passengers, and the relevant information is uploaded to the central processing system through the site control unit. The central processing system extracts the characteristic attributes of waiting passengers through image recognition, compares them with the recorded characteristic attributes of waiting passengers, and determines whether the passenger is standing on the platform for the first time within the time period. If so, the system records and stores the information with a number.

[0039] Since passengers are active, when a passenger walks down the pressure sensing area of ​​the waiting platform, the station pressure sensor detects the decrease in the total weight on the pressure sensing area and filters this change; when a passenger walks down the pressure sensing area of ​​the waiting platform and then walks up again, the station panoramic camera takes an image of the waiting passenger and uploads it. The central processing system compares and determines that this is not the first time the passenger has stepped onto the platform within this time period, and does not renumber the record and store it.

[0040] In this embodiment, after the on-board door opening and closing detector detects that the door is opened, the on-board pressure sensor starts to detect the weight change in the boarding area. When the weight increases by one human weight level, the on-board camera captures the image of the boarding passenger, the on-board control unit records the boarding time, and uploads the relevant information to the central processing system through the on-board control unit; when the on-board door opening and closing detector detects that the door is closed, the on-board camera stops shooting.

[0041] In this embodiment, the central processing system uses the door opening time during the working hours of the bus as the time node, queries the GPS information of the bus at the time node, and compares and matches it with the location information of the bus stop, finds the bus stop with a matching location, and calls the passenger arrival timetable of the bus stop. The timetable captures the one-hour range before the time when the first passenger gets on the bus, mainly based on the passengers getting on the bus, matches the passenger characteristics, subtracts the boarding time of the same passenger from the starting waiting time, and records it as the waiting time of the passenger, and combines the number of the passenger at the bus stop and the number on the bus as its ID for easy reference.

[0042] Figure 3 The following is a flow chart showing an implementation process of an embodiment of the method for identifying waiting passenger information and waiting time. Figure 3 As shown, the method comprises the following steps:

[0043] S101: The application scope of the present invention is within the working hours of buses on the bus route, and passengers before the departure of the first bus are not within this scope.

[0044] S102: Obtain the gravity data change of the pressure sensor at the current station, that is, the total weight of the pressure passengers on the bus station and their belongings.

[0045] S103: Determine whether the gravity data is in an increasing state.

[0046] S104: When a passenger gets on the bus stop, it is generally considered as the beginning of waiting for the bus. However, a passenger may leave the bus stop while waiting for the bus, but this does not affect the overall waiting time. Therefore, the gravity data is in a descending state and this change can be filtered.

[0047] S105: When the gravity data is in an increasing state, the characteristic attributes of the passenger causing the state change at this time node are compared with the record to determine whether the passenger is a newly added waiting passenger.

[0048] S106: If the passenger information has been recorded, by default, the passenger information has been recorded within 1 hour, then filter it.

[0049] S107: If the passenger is a new waiting passenger, record his information, number him and store him, as shown in Table 1.

[0050] S108: After the bus door opens, start recording.

[0051] S109: Determine whether the bus door opening time is within the working hours.

[0052] S110: If the bus door opening time is not within the working hours, for example, a bus is scheduled to depart at 9:00 and the previous task is completed at 8:30, then the bus door opening and closing changes are filtered in the time period between the two times; in addition, the bus status after get off work is also filtered.

[0053] S111: If the bus door opening time is within the working hours, the vehicle GPS information is recorded, which belongs to the bus stop information, so as to match it with the corresponding bus stop information.

[0054] S112: Obtaining gravity data changes of a vehicle-mounted pressure sensor installed in the vehicle boarding area.

[0055] S113: Determine whether the gravity data is in an increasing state.

[0056] S114: When the gravity data is not in an increasing state, it may be that passengers leave the boarding area in a crowded state and are filtered.

[0057] S115: When the gravity data is in an increasing state, the information of the boarding passengers is recorded, numbered and stored, as shown in Table 2.

[0058] S116: Compare the bus stop and bus information of the same GPS information. Generally, the passenger record of the bus stop within 1 hour before the first passenger of the bus is compared with the passenger information of the bus boarding within the time range from the opening to the closing of the bus door. The boarding passenger information is checked one by one to reduce the checking time.

[0059] S117: Determine whether the passenger is the same passenger, that is, whether the boarding passenger exists in both the bus stop record and the bus record.

[0060] S118: Determine whether the passenger information is only recorded at the bus stop but not recorded by the bus.

[0061] S119: The passenger information is only recorded at the bus stop but not by the bus. This means the passenger is a lost passenger and can be filtered.

[0062] S120: The passenger information is only recorded by the bus party, not by the bus station. The passenger is filtered out because he does not need to wait for the bus.

[0063] S121: When it is determined that the two passengers are the same, the passenger's waiting time is calculated.

[0064] S122: The passenger's waiting time is stored, and the passenger's waiting station and boarding bus information are recorded as a new table for storage, as shown in Table 3.
