Description

Technical Field

[0001] This application relates to the field of public transportation technology, and in particular to a method, apparatus, equipment and readable storage medium for evaluating transfer service capacity. Background Technology

[0002] Subway-bus transfer refers to the behavior of passengers switching between subway and bus modes of transportation during their journey. In related technologies, the evaluation of subway-bus transfer service levels mostly relies on survey data, and typically involves constructing evaluation models through case studies of selected sample stations, resulting in poor model applicability. While survey data can reflect actual transfer situations to a certain extent, evaluation results from only a few stations cannot represent the overall picture. Due to the complexity of passenger subway-bus transfer behavior and significant differences in characteristics across different time periods, on-site tracking surveys are difficult, easily overlooking the spatiotemporal differences in transfer levels between different rail stations, thus the reliability of the evaluation needs improvement. Summary of the Invention

[0003] This application provides a method, apparatus, equipment, and readable storage medium for evaluating transfer service capabilities, which can at least solve the problem that the reliability of subway-bus transfer service level evaluation needs to be improved in related technologies.

[0004] The first aspect of this application provides a method for evaluating transfer service capabilities, including:

[0005] Based on passenger flow data of all target stations within the target area and signaling data of the target area during a preset time period, the transfer demand evaluation parameters of the target subway station are calculated; among which, the target station includes the target subway station within the target area and at least one surrounding bus station;

[0006] Based on the transfer evaluation index values ​​of the target subway station, the evaluation parameters for the transfer supply capacity of the target subway station are determined; among which, the transfer evaluation index values ​​include the transfer cost index value and the transfer facility index value.

[0007] By combining the evaluation parameters of transfer demand and the evaluation parameters of each transfer supply capacity, the evaluation results of the public transport-subway transfer service capacity of the target area are generated.

[0008] A second aspect of this application provides an evaluation device for transfer service capability, comprising:

[0009] The first calculation module is used to calculate the transfer demand evaluation parameters of the target subway station based on the passenger flow data of all target stations in the target area within a preset time period and the signaling data of the target area; wherein, the target station includes the target subway station located in the target area and at least one surrounding bus station;

[0010] The second calculation module is used to calculate the evaluation parameters of the transfer supply capacity of the target subway station based on the transfer evaluation index values ​​of the target subway station; wherein, the transfer evaluation index values ​​include the transfer cost index value and the transfer facility index value.

[0011] The generation module is used to combine the transfer demand evaluation parameters and the transfer supply capacity evaluation parameters to generate the bus-subway transfer service capacity evaluation results for the target area.

[0012] A third aspect of this application provides an electronic device, including a memory and a processor, wherein the processor is configured to execute a computer program stored in the memory, and when the processor executes the computer program, it implements the steps in the evaluation method for transfer service capability provided in the first aspect of this application.

[0013] The fourth aspect of this application provides a computer-readable storage medium storing a computer program thereon. When the computer program is executed by a processor, it implements the steps in the evaluation method for transfer service capability provided in the first aspect of this application.

[0014] As can be seen from the above, based on the evaluation method, device, equipment, and readable storage medium for transfer service capacity provided in this application, the transfer demand evaluation parameters of the target subway station are calculated based on passenger flow data of all target stations within the target area and signaling data of the target area during a preset time period. The target stations include the target subway station within the target area and at least one surrounding bus station. Based on the transfer evaluation index values ​​of the target subway station, the transfer supply capacity evaluation parameters of the target subway station are determined. The transfer evaluation index values ​​include transfer cost index values ​​and transfer facility index values. Combining the transfer demand evaluation parameters and each transfer supply capacity evaluation parameter, the evaluation result of the bus-subway transfer service capacity of the target area is generated. Through the implementation of this application, demand assessment is conducted by combining bus passenger flow data and signaling data of the target area, and supply capacity assessment is conducted by combining the cost index of transfers between the target subway station and surrounding bus stations and the facility index of the target subway station. This allows for a more realistic and effective reflection of the subway-bus transfer level, providing a valid reference for identifying subway stations with mismatched transfer supply and demand or insufficient supply.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0023] To address the issue of insufficient reliability in evaluating the service level of subway-bus transfers in related technologies, the first embodiment of this application provides a method for evaluating transfer service capacity, such as... Figure 1This is a basic flowchart illustrating the evaluation method for transfer service capability provided in this embodiment. The evaluation method for transfer service capability includes the following steps:

[0024] Step 101: Based on the passenger flow data of all target stations in the target area within the preset time period and the signaling data of the target area, calculate the transfer demand evaluation parameters of the target subway station.

[0025] Specifically, target stations include the target subway station and at least one nearby bus stop within the target area. The preset time period can refer to a week, a month, a quarter, half a year, a year, etc., without limitation. Passenger flow data can be obtained from bus card swipe data, or it can be determined by combining it with video surveillance data from buses, without limitation. Signaling data is a type of spatiotemporal trajectory big data, representing the spatiotemporal trajectory left by mobile phone users' activities in the mobile communication network. Signaling data for the target area within the preset time period can be obtained through mobile phone operators.

[0026] Step 102: Based on the transfer evaluation index values ​​of the target subway station, determine the evaluation parameters of the transfer supply capacity of the target subway station.

[0027] Specifically, the evaluation indicators for transfers include transfer cost indicators and transfer facility indicators.

[0028] Step 103: Combine the transfer demand evaluation parameters and the transfer supply capacity evaluation parameters to generate the bus-subway transfer service capacity evaluation results for the target area.

[0029] Specifically, a relationship table between evaluation parameters and evaluation levels can be pre-set and stored in the system. This allows for comparison of the transfer demand evaluation parameters and transfer supply capacity evaluation parameters with this relationship table to determine the evaluation levels of the transfer demand evaluation parameters and transfer supply capacity evaluation parameters. The evaluation results of the transfer service capacity between the target subway station and surrounding bus stations can then be generated by combining the evaluation levels.

[0030] In one embodiment of this example, before calculating the transfer demand evaluation parameters of the target subway station based on the passenger flow data of all target stations within the target area and the signaling data of the target area during the preset time period, the scope of the target area can also be determined based on the relevant passenger flow data.

[0031] Specifically, the transfer travel chain for each passenger can be generated based on the ID matching results of passenger card swipe data (bus card swipe data and subway card swipe data). Figure 2As shown, based on the transfer travel chain, information such as passenger transfer time, transfer distance characteristics (preceding and subsequent transfers), and overall travel distance characteristics (preceding and subsequent trips) can be determined. Then, by analyzing and statistically analyzing each transfer travel chain, the proportion of transfer passengers corresponding to different transfer distances can be confirmed. Based on the transfer distance corresponding to the proportion of target transfer passengers, the scope of the target area can be determined. The scope of the target area can include the first scope corresponding to the transfer demand evaluation and the second scope corresponding to the transfer supply evaluation.

[0032] As an example, if the target proportion of transfer passengers is set at 80%, and if 80% of metro-bus transfer passengers transfer at bus stops within 800 meters of the target metro station, and the actual straight-line distance between these transfer passengers' alighting points and the metro station is greater than 1.5 km, then the area with a radius of 800 meters centered on the target metro station can be defined as the first range mentioned above, and the area with a radius of 1.5 km centered on the target metro station can be defined as the second range mentioned above. That is, for the evaluation of transfer demand, it can be estimated based on the number of users whose destinations in the transfer travel chain are more than 1.5 km from the metro station; for the evaluation of transfer supply, it can be evaluated based on the number and frequency of bus stops within 800 meters of the metro station.

[0033] In one embodiment of this example, the step of calculating the transfer demand evaluation parameters of the target subway station based on passenger flow data of all target stations within the target area and signaling data of the target area during a preset time period includes: based on passenger flow data of all target stations within the target area during a preset time period, counting the actual number of transfers between the target subway station and surrounding bus stations and the number of exits from all target stations; based on signaling data of the target area during the preset time period, determining the transfer demand rate of the target subway station; and combining the number of exits, the actual number of transfers, and the transfer demand rate to calculate the transfer demand evaluation parameters of the target subway station.

[0034] Specifically, the aforementioned passenger flow data can include bus card swipe data from surrounding bus stops and card swipe data from the target subway station. The actual number of transfer passengers can be determined by analyzing and statistically analyzing each transfer travel chain.

[0035] Furthermore, in one embodiment of this example, the step of determining the transfer demand rate of the target subway station based on the signaling data of the target area within a preset time period includes: splicing travel chains based on the signaling data of the target area within a preset time period to determine the full travel chain of each traveler passing through the target area; identifying the dwell point for each full travel chain to determine the actual number of transfers between the target subway station and surrounding bus stations, as well as the target number of transfers with transfer needs; wherein, the passengers corresponding to the target number of transfers include passengers who have actually transferred and passengers who have transfer needs but have not actually transferred; and determining the transfer demand rate of the target subway station as the ratio of the target number of transfers to the number of exits.

[0036] Specifically, transfer data for the target area can be obtained from mobile operators (e.g., China Mobile, China Unicom, China Telecom, etc.). By analyzing the signal and time information of mobile phones accessing different base stations in mobile signaling data, the user's entire travel chain can be identified and extracted. If the mobile signaling stays at the same location for more than a preset time threshold (e.g., 30 minutes), that location can be identified as a dwell point. The base station location between two consecutive dwell points can be identified as the intermediate travel chain. Rail stations are equipped with dedicated mobile base stations, which can effectively identify users' rail travel process data. Based on this, the entire travel chain of all rail users can be extracted from the mobile signaling data, identifying the distance characteristics between the travel origin and destination and the subway entrance / exit stations. Then, the transfer demand rate of the target area can be calculated based on these distance characteristics. In one specific implementation, the proportion of passengers exiting surrounding bus stations whose destination is more than 1.5km away from the target subway station can be determined as the transfer demand rate of the target subway station.

[0037] Furthermore, in one embodiment of this example, the transfer demand evaluation parameters include the potential transfer demand between the target subway station and each surrounding bus station, and the corresponding transfer demand gap parameters; the step of calculating the transfer demand evaluation parameters of the target subway station by combining the number of exiting passengers, the actual number of transfer passengers, and the transfer demand rate includes: calculating the number of exiting passengers B0 and the transfer demand rate R. L The product of these two factors yields the potential transfer demand M (M = B). 0* R L ); Calculate the potential transfer demand M and the actual number of transfer passengers B. t The difference is used to obtain the transfer demand gap parameter G (G = MB). t ).

[0038] Furthermore, after determining the potential transfer demand and the corresponding transfer demand gap parameters, the corresponding potential transfer demand level and transfer demand gap level can be found based on the system's preset transfer demand level comparison table (as shown in Table 1).

[0039] Table 1:

[0040] Number of people Below 1000 1000～5000 5000 and above Potential demand level for transfers Low middle high Transfer demand gap level Low middle high

[0041] In one embodiment of this example, the step of calculating the transfer supply capacity evaluation parameter of the target subway station based on the transfer evaluation index value of the target subway station includes: standardizing each transfer evaluation index value of the target subway station to obtain the corresponding standardized index value; and calculating the transfer supply capacity evaluation parameter of the target subway station by combining each standardized index value.

[0042] Specifically, after standardizing the various transfer evaluation indicators, the entropy weight-TOPSIS model can be used to evaluate the metro-bus transfer supply level of the target metro station. In other words, the entropy weight method and the TOPSIS method can be combined to efficiently evaluate the transfer supply capacity between the target metro station and the surrounding bus stations.

[0043] Further, in one embodiment of this example, the transfer cost index value includes at least one of the average transfer time and average transfer distance between surrounding bus stops and the target subway station, and the transfer facility index value includes at least one of the number of entrances and exits of the target subway station, the number of surrounding bus stops, the number of all target bus routes corresponding to the surrounding bus stops, and the service area area of ​​the target bus routes; the step of standardizing each transfer evaluation index value of the target subway station to obtain the corresponding standardized index value includes: standardizing the transfer facility index value of the target subway station based on the first calculation formula to obtain the first standardized index value; wherein, the first calculation formula is expressed as:

[0044]

[0045] Based on the second calculation formula, the transfer cost index value of the target subway station is standardized to obtain the second standardized index value; wherein, the second calculation formula is expressed as:

[0046]

[0047] Z′ j Z″ represents the first standardized index value. j x represents the second standardized index value. j Let x represent the value of the j-th transfer evaluation index, where 2 ≤ j ≤ 7. max x represents the maximum value among all transfer evaluation index values. min This represents the minimum value among all transfer evaluation index values.

[0048] Specifically, standardization can eliminate the different dimensions and units of measurement for different transfer evaluation indicators. For transfer facilities, which are positive indicators, the higher the calculated value of the first standardized indicator, the better; for transfer costs, which are negative indicators, the lower the calculated value of the second standardized indicator, the better.

[0049] Furthermore, in one embodiment of this example, the above-mentioned calculation of the transfer supply capacity evaluation parameters of the target subway station by combining each standardized index value includes: calculating the objective weight of each standardized index value respectively; combining each standardized index value and the corresponding objective weight to calculate the positive ideal solution distance and the negative ideal solution distance of the transfer evaluation index; calculating the relative proximity of the positive ideal solution distance and the negative ideal solution distance, and determining the relative proximity as the transfer supply capacity evaluation parameter of the target subway station.

[0050] Furthermore, when there are multiple target subway stations (e.g., n stations), the following calculation formula can be used:

[0051] (1) Calculate the objective weights of each standardized indicator value:

[0052]

[0053] D j =1-E j

[0054]

[0055] Where i represents the i-th subway station; P represents the characteristic value of the evaluation index; E represents the information entropy value of the evaluation index; D represents the information utility value; and W represents the objective weight mentioned above. The larger the objective weight, the more important the index.

[0056] (2) Determine the positive and negative ideal solutions and calculate the distance:

[0057] Multiply each of the first and second standardized index values ​​by its corresponding objective weight to obtain the ideal solution C. Then, calculate the distance between the evaluation index of each target subway station and the positive and negative ideal solutions:

[0058] The distance to the ideal solution:

[0059] Distance to negative ideal solution:

[0060] Among them, C + =(maxC i1 maxC i2 ..., maxC i7 C - =(minC i1 minC i2, ..., minC i7 ).

[0061] (4) Calculate the relative closeness between the comprehensive evaluation index of each target subway station and the ideal solution, that is, calculate the evaluation parameter F of the transfer supply capacity:

[0062]

[0063] A higher F-value indicates a better level of transfer supply. Therefore, the F-value can be used to determine the evaluation level of transfer supply capacity between the target subway station and surrounding bus stations. For example, the transfer supply levels of each target subway station can be ranked, and the evaluation level of transfer supply capacity can be divided into three levels according to the size of the F-value: low transfer supply level (0-0.3), medium transfer supply level (0.3-0.5), and high transfer supply level (0.5-1).

[0064] In one embodiment of this example, the above-mentioned combination of transfer demand evaluation parameters and transfer supply capacity evaluation parameters to generate service capacity evaluation results between the target subway station and surrounding bus stations includes: based on a preset subway-bus transfer supply and demand matching evaluation table (as shown in Table 2), combined with the above-mentioned potential transfer demand level, transfer demand gap level and transfer supply capacity evaluation level, to generate service capacity evaluation results between the target subway station and surrounding bus stations, thereby determining the transfer optimization strategy for the target subway station based on the above-mentioned service capacity evaluation results.

[0068] The technical solution of this application, based on passenger flow data of all target stations within a target area and signaling data of the target area over a preset time period, calculates the transfer demand evaluation parameters of the target subway station. The target stations include the target subway station within the target area and at least one surrounding bus station. Based on the transfer evaluation index values ​​of the target subway station, the transfer supply capacity evaluation parameters of the target subway station are determined. The transfer evaluation index values ​​include transfer cost index values ​​and transfer facility index values. Combining the transfer demand evaluation parameters and each transfer supply capacity evaluation parameter, the bus-subway transfer service capacity evaluation result of the target area is generated. By implementing this solution, demand assessment is performed by combining bus passenger flow data and signaling data of the target area, and supply capacity assessment is performed by combining the cost index of transfers between the target subway station and surrounding bus stations with the facility index of the target subway station. This allows for a more accurate reflection of the subway-bus transfer level and provides an effective reference for identifying subway stations with mismatched transfer supply and demand or insufficient supply.

[0069] Figure 3 The method described in the second embodiment of this application is a refined method for evaluating transfer service capabilities, which includes:

[0070] Step 301: Obtain passenger flow data and signaling data of all target stations within the target area during the preset time period.

[0071] Specifically, the target stations include the target subway station and at least one nearby bus station within the target area.

[0072] Step 302: Based on passenger flow data, count the actual number of transfers between the target subway station and surrounding bus stations, as well as the number of passengers exiting all target stations.

[0073] Step 303: Determine the transfer demand rate of the target subway station based on the signaling data of the target area within the preset time period.

[0074] Step 304: Calculate the product of the number of people exiting the station and the transfer demand rate to obtain the potential transfer demand of the target subway station.

[0075] Step 305: Calculate the difference between potential transfer demand and actual number of transfers to obtain the transfer demand gap parameter of the target subway station.

[0076] Step 306: Standardize the values ​​of each transfer evaluation index of the target subway station to obtain the corresponding standardized index values.

[0077] Specifically, the transfer evaluation index values ​​include transfer cost index values ​​and transfer facility index values. The transfer cost index value includes at least one of the average transfer time and average transfer distance between the surrounding bus stations and the target subway station. The transfer facility index value includes at least one of the number of entrances and exits of the target subway station, the number of surrounding bus stations, the number of all target bus routes corresponding to the surrounding bus stations, and the service area area of ​​the target bus routes.

[0078] Step 307: Calculate the evaluation parameters of the transfer supply capacity of the target subway station by combining the values ​​of each standardized indicator.

[0079] Step 308: Combine the potential transfer demand, transfer demand gap parameters, and transfer supply capacity evaluation parameters to generate the evaluation results of the public transport-subway transfer service capacity of the target area.

[0080] By implementing this embodiment, signaling data, passenger flow data, and transfer cost and transfer facility indicators between the target subway station and surrounding bus stations are combined to comprehensively evaluate the bus-subway transfer service level from the perspectives of transfer demand and subway station supply capacity. The data is more comprehensive, the analysis is more objective, and the evaluation results are more reliable.

[0081] It should be understood that the sequence number of each step in this embodiment does not imply the order in which the steps are executed. The execution order of each step should be determined by its function and internal logic, and should not constitute a unique limitation on the implementation process of this application embodiment.

[0087] Furthermore, in some embodiments of this example, when the first calculation module performs the function of determining the transfer demand rate of the target subway station based on the signaling data of the target area within a preset time period, it is specifically used to: splice travel chains based on the signaling data of the target area within a preset time period to determine the full travel chain of each traveler passing through the target area; identify the dwell point for each full travel chain to determine the target number of transfer passengers with transfer needs; wherein, the passengers corresponding to the target number of transfer passengers include passengers who have actually transferred and passengers who have transfer needs but have not actually transferred; and determine the transfer demand rate of the target subway station as the ratio of the target number of transfer passengers to the number of passengers exiting the station.

[0088] Furthermore, in some embodiments of this example, the transfer demand evaluation parameters include the potential transfer demand between the target subway station and surrounding bus stations and the corresponding transfer demand gap parameters. Accordingly, when the first calculation module performs the function of calculating the transfer demand evaluation parameters of the target subway station by combining the number of exits, the actual number of transfers, and the transfer demand rate, it is specifically used to: calculate the product of the number of exits and the transfer demand rate to obtain the potential transfer demand; and calculate the difference between the potential transfer demand and the actual number of transfers to obtain the transfer demand gap parameters.

[0090] Furthermore, in some embodiments of this example, the transfer cost index value includes at least one of the average transfer time and average transfer distance between surrounding bus stations and the target subway station, and the transfer facility index value includes at least one of the number of entrances and exits of the target subway station, the number of surrounding bus stations, the number of all target bus routes corresponding to the surrounding bus stations, and the service area area of ​​the target bus routes; correspondingly, when the second calculation module performs the function of standardizing each transfer evaluation index value of the target subway station to obtain the corresponding standardized index value, it is specifically used to: standardize the transfer facility index value of the target subway station based on the first calculation formula to obtain the first standardized index value; wherein, the first calculation formula is expressed as:

[0091]

[0092] Based on the second calculation formula, the transfer cost index value of the target subway station is standardized to obtain the second standardized index value; wherein, the second calculation formula is expressed as:

[0093]

[0094] Z′ j Z″ represents the first standardized index value. j x represents the second standardized index value. j Let x represent the value of the j-th transfer evaluation index, where 2 ≤ j ≤ 7. max x represents the maximum value among all transfer evaluation index values. min This represents the minimum value among all transfer evaluation index values.

[0095] Furthermore, in some embodiments of this example, when the second calculation module performs the function of calculating the transfer supply capacity evaluation parameters of the target subway station by combining the standardized index values, it is also specifically used to: calculate the objective weight of each standardized index value respectively; combine each standardized index value and the corresponding objective weight to calculate the positive ideal solution distance and negative ideal solution distance of the transfer evaluation index; calculate the relative proximity of the positive ideal solution distance and the negative ideal solution distance, and determine the relative proximity as the transfer supply capacity evaluation parameter of the target subway station.

[0096] According to the evaluation device for transfer service capacity provided in this embodiment, based on passenger flow data of all target stations within a target area and signaling data of the target area during a preset time period, the transfer demand evaluation parameters of the target subway station are calculated. The target stations include the target subway station within the target area and at least one surrounding bus station. Based on the transfer evaluation index values ​​of the target subway station, the transfer supply capacity evaluation parameters of the target subway station are determined. The transfer evaluation index values ​​include transfer cost index values ​​and transfer facility index values. Combining the transfer demand evaluation parameters and each transfer supply capacity evaluation parameter, the bus-subway transfer service capacity evaluation result of the target area is generated. Through the implementation of this embodiment, demand assessment is performed by combining bus passenger flow data and signaling data of the target area, and supply capacity assessment is performed by combining the cost index of transfers between the target subway station and surrounding bus stations and the facility index of the target subway station. This allows for a more realistic reflection of the subway-bus transfer level and provides an effective reference for identifying subway stations with mismatched transfer supply and demand or insufficient supply.
