[0017] In order to make the above and other features and advantages of the present application more clear, the present application is further described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are only exemplary and not restrictive.

[0018] In the following description, many specific details are set forth to provide a thorough understanding of the present application. However, it is apparent to those skilled in the art that specific details need not be adopted to practice the present application. In other cases, well-known steps or operations are not described in detail to avoid blurring the present application.

[0019] On the one hand, an embodiment of the present application provides an intelligent public transportation system. Figure 1 A schematic diagram of the structure of a bus dispatching system provided by an embodiment of the present application is shown as follows: Figure 1 As shown, the intelligent public transportation system 10 may include a public transportation management platform 11, a bus terminal 12 arranged on each bus, and an electronic bus stop sign 13 set up at each bus stop.

[0020] The bus management platform 11, the bus terminal 12 and the electronic bus stop 13 can communicate with each other. The bus management platform 11 can receive weather information from the weather forecast platform, filter and integrate it according to the bus's route, and generate weather information along the bus route.

[0021] The bus management platform 11 pushes weather information along the way to the bus terminal 12 and the electronic bus stop 13. The bus terminal 12 and the electronic bus stop 13 display the weather information along the way, so that passengers can understand the weather information along the way through the bus terminal and the electronic bus stop during riding or waiting, so as to make travel preparations in advance.

[0022] In addition, the electronic bus stop sign 13 can also be used to display the arrival information and route information of the bus.

[0023] In order to reduce the impact of weather on bus driving safety, in some embodiments, the bus management platform 11 can execute any bus scheduling method provided in the embodiments of the present application to match the optimal bus and driver according to the weather safety index of the target shift, thereby reducing the impact of weather on bus driving safety and improving travel safety.

[0024] On the other hand, an embodiment of the present application provides a bus dispatching method, which can be applied to a bus management platform 11. Figure 2 A schematic diagram of a process of a bus dispatching method provided by an embodiment of the present application is shown as follows: Figure 2 As shown, the bus scheduling method may include the following steps.

[0025] S21, determining the weather safety index of the target bus route based on the current weather forecast data and the departure time of the target bus.

[0026] The current weather forecast data involved in one embodiment of the present application may be the weather forecast data most recently acquired before the departure time. The weather safety index is a quantitative index that can be used to reflect the relative safety of a bus traveling on a specific route under predicted weather conditions. The target bus may refer to any bus whose departure time is after the time when the current weather forecast data is acquired. The travel time of the target bus is within the predicted time period in the current weather forecast data.

[0027] In an embodiment of the present application, the bus management platform 11 can query the weather forecast data within a preset period from the weather forecast platform, wherein the preset period can be set according to user needs, for example, the preset duration can be 12 hours. And according to the departure time of the target bus, the weather forecast data of the target bus time is selected from the queried weather forecast data, wherein the departure time of the target bus is the planned departure time. The target bus time can refer to the time period from the departure time to the time when the bus arrives at the final stop.

[0028] The bus management platform 11 analyzes the impact of the weather forecast data of the corresponding time period on the driving safety of the bus, and calculates the weather safety index of the bus on the driving route in the corresponding time period. The driving route can be the bus route corresponding to the target shift.

[0029] S22, obtaining the driving safety index of the available drivers of the target shift and the vehicle safety index of the available buses.

[0030] The target shift available driver involved in one embodiment of the present application may refer to a driver who is idle during the target shift time. The available bus may be a bus that is idle during the target shift time. The driving safety index may be used to reflect the driving ability and safety of the driver under various weather conditions. The vehicle safety index may reflect the reliability and safety of the bus.

[0031] In one embodiment of the present application, the bus management platform 11 can calculate a driving safety index for each driver based on the driving record of each driver. The driving record may include but is not limited to accident rates, driving skills, and bad driving behaviors under various weather conditions. In addition, the bus management platform 11 can calculate a vehicle safety index for each bus based on the vehicle information of each bus. The vehicle information may include vehicle type, age, failure rate, repair record, and maintenance status.

[0032] It should be noted that the higher the driving safety index, the higher the driver's driving ability and safety. The higher the vehicle safety index, the higher the reliability and safety of the vehicle.

[0033] In addition, the bus management platform 11 selects idle drivers and buses within the target shift time as available drivers and available buses for the target shift according to the bus attendance records.

[0034] S23, inputting the weather safety index, the driving safety index of the available drivers, and the vehicle safety index of the available buses into a pre-trained bus dispatching model to determine the buses and drivers used for the target shift.

[0035] The pre-trained bus dispatch model involved in one embodiment of the present application refers to a trained bus dispatch model. The bus dispatch model is a model constructed based on a dispatch algorithm combined with an optimization algorithm, and is trained based on a dispatch data set. The dispatch data set includes actual weather safety indexes in various time periods, driving safety indexes of multiple drivers and vehicle safety indexes of buses, and driver and bus combinations matched based on expert experience.

[0036] The bus and driver used for the target shift involved in one embodiment of the present application refer to the optimal bus and driver that match the weather conditions corresponding to the target shift time. Among them, the optimal bus and driver may refer to the bus and driver combination with the highest driving safety during the driving process.

[0037] In one embodiment of the present application, the weather safety index, the driving safety index of available drivers and the vehicle safety index of available buses are used as inputs of the bus dispatch model. The bus management platform 11 inputs various safety indexes into the bus dispatch model to calculate the bus and driver combination with the best target shift.

[0038] In the above embodiments, the weather safety index of the target bus route is determined based on the current weather forecast data and the departure time of the target bus, so that the impact of the weather conditions along the target bus route on the driving safety can be quantified. The driving safety index of the available drivers of the target shift and the vehicle safety index of the available buses are obtained, and the weather safety index, the driving safety index of the available drivers and the vehicle safety index of the available buses are input into the pre-trained bus scheduling model to determine the bus and driver used for the target shift. In this way, by comprehensively considering the weather safety index, the driving safety index of the driver and the vehicle safety index of the bus, the operating conditions of the target bus can be evaluated more comprehensively and accurately, so as to select the optimal bus and driver combination, effectively reduce the risk of traffic accidents, improve the accuracy of scheduling, and make full use of weather forecast data and real-time bus operation data, so as to flexibly schedule buses and drivers according to specific predicted weather conditions to ensure the effective use of resources.

[0039] In some embodiments, the dispatching target of the bus dispatching model may be the highest safety. S23, inputting the weather safety index, the driving safety index of the available drivers, and the vehicle safety index of the available buses into the pre-trained bus dispatching model to determine the bus and driver used for the target shift, may include: inputting the weather safety index, the driving safety index of the available drivers, and the vehicle safety index of the available buses into the bus dispatching model; determining the safety scores of multiple driver and bus combinations that match the weather safety index through the bus dispatching model; and selecting the bus and driver combination with the highest score as the bus and driver used for the target shift.

[0040] In one embodiment of the present application, the bus dispatch model first matches each available driver with each available bus to generate all available combinations. A safety score is calculated for each combination based on the driving safety index of all available drivers, the vehicle safety index of all available buses, and the weather safety index. Based on the safety score of each combination, the bus and driver combination with the highest score is selected as the bus and driver used for the target shift.

[0041] In one embodiment of the present application, the calculation formula for the safety score of the driver and bus combination may be the following formula.

[0042] S=α×W+β×D-γ×V (1)

[0043] Among them, S represents the safety score, W represents the driving safety index, D represents the vehicle safety index, V represents the weather index, and α, β, and γ represent the weight coefficients of the three. It should be noted that the weight coefficients are obtained through pre-training.

[0044] In one embodiment of the present application, when the safety scores of two combinations are the same, the combination with the lowest cost of driver and bus is selected as the bus and driver used for the target shift. The combination cost can be calculated based on the cost of using the bus and the salary of the driver.

[0045] In the above embodiment, the bus dispatching model can effectively select the bus and driver combination that best suits the current weather conditions according to the weather safety index, the driver's driving safety and the bus vehicle safety index, thereby improving driving safety.

[0046] In some embodiments, since the mileage of the bus route is relatively long, the weather conditions of each road section are comprehensively considered when evaluating the weather of the bus route.

[0047] S21, based on the current weather forecast data and the departure time of the target bus, determining the weather safety index of the target bus route, may include: determining the time for the target bus to travel to each section in the route based on the departure time of the target bus and the location of each station on the route; based on the time for the target bus to travel to each section in the route, obtaining the weather forecast data for each section at the corresponding time from the current weather data; based on the weather forecast data, using a weather safety index evaluation model to determine the weather safety index of the target bus route.

[0048] The road section involved in an embodiment of the present application may be a road between adjacent stations. The weather safety index evaluation model is used to evaluate the impact of weather on the entire bus route.

[0049] In one embodiment of the present application, the bus management platform 11 can obtain the bus stop schedule, and query the time it takes for the target bus to travel to each section of the route based on the departure time of the target bus and the location of each stop on the route.

[0050] In another embodiment of the present application, the bus management platform 11 can obtain the departure time of the target bus, the location of each station on the bus route and the bus speed without obtaining the bus station schedule. The relative mileage between each section can be calculated based on the location of each station, and the travel time of each section can be estimated based on the bus speed. Based on the historical waiting time and travel time of each section, the time for the target bus to travel to each section in the route can be obtained, so that a more accurate arrival time can be obtained, so as to obtain a more accurate weather forecast later.

[0051] In one embodiment of the present application, the bus management platform 11 selects weather forecast data for the corresponding time of each section from the current weather forecast data according to the time when the target bus arrives at each section in the route and the location of each section.

[0052] In one embodiment of the present application, the bus management platform 11 can use the weather safety index evaluation model to perform weather safety evaluation on each road section based on the weather forecast data at the corresponding time of each road section, and comprehensively evaluate the weather safety of each road section to obtain the weather safety index of the entire target bus route.

[0053] In the above embodiment, by determining the time when the target bus will arrive at each section of the road, obtaining the weather forecast data for each section within the corresponding time, and using the weather safety index assessment model to conduct a safety assessment on the weather conditions of the entire driving route based on the weather data of each section, a weather safety index that can reflect the weather conditions of the entire driving route is obtained, thereby providing favorable support for subsequent bus scheduling.

[0054] In some embodiments, based on weather forecast data, using a weather safety index assessment model, determining the weather safety index of a target bus route includes: inputting the weather forecast data for the corresponding time of each road section into the weather safety index assessment model; converting the weather forecast data for the corresponding time of each road section into a weather index corresponding to each road section through a weather coefficient conversion module of the weather safety index assessment model; and determining the weather safety index of the target bus route based on the mileage and weather index of each road section through a weather safety index calculation module of the weather safety index assessment model.

[0055] In one embodiment of the present application, Figure 3 A schematic diagram showing the structure of a weather safety index evaluation model provided by an embodiment of the present application is shown as follows: Figure 3 As shown, the weather safety index evaluation model 30 may include a weather coefficient conversion module 31 and a weather safety index calculation module 32. The weather coefficient conversion module 31 is used to convert weather data into a weather index related to weather safety. The weather index reflects the safety of the road section under specific weather conditions.

[0056] The weather safety index calculation module 32 can be used to calculate the weather safety index of the entire driving route according to the weather index of each road section and the corresponding mileage.

[0057] In an embodiment of the present application, the weather coefficient conversion module 31 can convert various types of weather data into weather indices according to preset conversion rules. The preset rules can be set based on the degree of influence of weather data on bus driving safety. For example, the preset conversion rules may include clear corresponding to 0, cloudy corresponding to 0, light snow corresponding to 1, moderate snow corresponding to 2, heavy snow corresponding to 3, and blizzard corresponding to 4, etc.

[0058] In the above embodiment, the weather index of each road section is obtained based on the weather data of each road section at the corresponding time through the weather coefficient conversion module, and the weather index of each road section and the corresponding mileage are integrated through the weather safety index calculation module 32 to calculate the weather safety index of the entire driving route, thereby improving the accuracy and practicality of the weather safety index.

[0059] In some embodiments, determining the weather safety index of the target bus route based on the mileage and weather index of each road segment includes: calculating the weather safety index using the following formula.

[0060]

[0061] Among them, L i represents the mileage of the i-th road section, Ki represents the weather index of the i-th road section, and n represents the total number of road sections on the driving route.

[0062] That is to say, the weather safety index calculation module 32 obtains the weather safety index of the target bus route by using an additive fusion method, that is, the product of the weather index and the mileage of each section is added to obtain the weather safety index of the entire route.

[0063] In the above embodiment, the product of the weather index and mileage of each road section is added to obtain the weather safety index of the entire driving route. The weather safety index comprehensively considers the impact of weather conditions and mileage on the safe driving of the bus, providing strong support for subsequent bus scheduling strategies.

[0064] In some embodiments, the weather safety index calculation module 32 may also obtain the weather safety index of the target bus route by weighted fusion, that is, according to the road type of each road section, obtain the corresponding road section weight coefficient.

[0065] It should be noted that the conversion rules between road types and road section weighting coefficients are determined according to the degree to which the safety of different types of roads is affected by weather. For example, the safety of bridge decks is easily affected by weather, and the road section weighting coefficient is relatively large.

[0066] The calculation formula of the weather safety index can also be expressed as the following formula.

[0067]

[0068] Wherein, ωi represents the link weighting coefficient of the i-th link.

[0069] In the above embodiment, the weather index, mileage and product of the section weighted coefficient of each road section are added together to obtain the weather safety index of the entire driving route. The weather safety index comprehensively considers the impact of road type, weather conditions and mileage on the safe driving of buses, providing strong support for subsequent bus scheduling strategies.

[0070] In some embodiments, the bus dispatching method further includes: during the driving process of the bus used for the target shift, obtaining weather forecast data for each section of the driving route according to a preset time frequency.

[0071] In an embodiment of the present application, the preset time frequency may be the time frequency at which the weather forecast platform updates the weather forecast. For example, the preset time frequency may be 1 hour. During the driving process of the bus used for the target shift, the bus management platform 11 obtains updated weather forecast data from the weather forecast platform according to the preset time frequency, and then screens the weather forecast data of each road section according to the location of each road section and the corresponding time, so as to timely release the updated weather forecast data on the driving route, so that passengers can prepare countermeasures in advance.

[0072] In some embodiments, after obtaining weather forecast data for each section of the driving route at a preset time frequency, the bus scheduling method also includes: comparing the difference between the most recent weather forecast data for each section and the previous weather forecast data for each section to determine weather difference information; updating the weather difference information to the bus terminal of the bus used by the target shift and / or updating it to the electronic bus stop sign of each station corresponding to the difference information.

[0073] In one embodiment of the present application, since the weather forecast data between two consecutive times will not change on a large scale, the public transportation management platform 11 compares the difference between the most recent weather forecast data of each road section and the previous weather forecast data of each road section to determine the weather difference information. The difference information includes the station and the latest weather data of the road section where the weather data has changed.

[0074] The bus management platform 11 pushes the weather difference information to the bus terminal 12 of the bus used by the target shift, or to the electronic bus stop 13 of each station corresponding to the weather difference information, or to the bus terminal of the bus used by the target shift and the electronic bus stop 13 of each station corresponding to the weather difference information.

[0075] Since the public transportation management platform 11 sends the corresponding weather forecast data to the electronic stop board of each station corresponding to the weather difference information, the weather forecast data of the electronic stop board of each station corresponding to the weather difference information changes, while the weather forecast data of the electronic stop board of other stations except the electronic stop board of each station corresponding to the weather difference information does not change.

[0076] In the above embodiment, the weather difference information is updated to the bus terminal and / or updated to the electronic stop board of each station corresponding to the difference information, which can facilitate the bus terminal to timely update the weather forecast data of the corresponding road section based on the weather difference information, so that the driver and passengers can view the latest weather forecast data in real time, and facilitate the electronic stop board to timely update the weather forecast data of the corresponding station based on the weather difference information, ensuring that passengers can also obtain the latest weather conditions when waiting for the bus. In addition, since the amount of difference information data is small, the time required for the bus management platform 11 to transmit the difference information is relatively short, so that the bus terminal and the electronic stop board can quickly complete the weather forecast update.

[0077] On the other hand, an embodiment of the present application provides a bus dispatching device that can be applied to a bus management platform 11. Figure 4 FIG. 1 is a schematic diagram showing the structure of a bus dispatching device provided by an embodiment of the present application.

[0080] The bus and driver determination module 43 is used to input the weather safety index, the driving safety index of the available drivers and the vehicle safety index of the available buses into the pre-trained bus scheduling model to determine the bus and driver used for the target shift.

[0081] In the above embodiment, the weather safety index of the target bus route is determined based on the current weather forecast data and the departure time of the target bus, so that the impact of the weather conditions along the target bus route on the driving safety can be quantified. The driving safety index of the available drivers of the target shift and the vehicle safety index of the available buses are obtained, and the weather safety index, the driving safety index of the available drivers and the vehicle safety index of the available buses are input into the pre-trained bus scheduling model to determine the bus and driver used for the target shift. In this way, by comprehensively considering the weather safety index, the driving safety index of the driver and the vehicle safety index of the bus, the operating conditions of the target bus can be evaluated more comprehensively and accurately, so as to select the optimal bus and driver combination, effectively reduce the risk of traffic accidents, improve the accuracy of scheduling, and make full use of weather forecast data and real-time bus operation data, so as to flexibly schedule buses and drivers according to specific predicted weather conditions to ensure the effective use of resources.

[0083] The index input unit is used to input the weather safety index, the driving safety index of available drivers, and the vehicle safety index of available buses into the bus dispatch model.

[0084] The score determination unit is used to determine the safety scores of multiple driver-bus combinations matching the weather safety index through a bus dispatch model.

[0092]

[0093] Among them, Li represents the mileage of the i-th road section, and Ki represents the weather index of the i-th road section.

[0094] In some embodiments, the bus dispatching device 40 may include a weather data periodic acquisition module for acquiring weather forecast data for each section of the travel route at a preset time frequency during the travel of the bus used for the target shift.

[0095] In some embodiments, the bus dispatching device 40 may also include an updating module for obtaining weather forecast data for each section in the driving route at a preset time frequency, comparing the difference between the most recent weather forecast data for each section and the previous weather forecast data for each section, and determining weather difference information; updating the weather difference information to the bus terminal of the bus used for the target shift and / or updating it to the electronic bus stop sign of each station corresponding to the weather difference information.
