[0002] Subway-bus transfer refers to the behavior of passengers switching between the subway and bus during their travel. In related technologies, the evaluation of subway-bus transfer service levels mostly uses survey data, and usually constructs an evaluation model by selecting some sample stations for case analysis, and the model has poor applicability. Although the survey data can reflect the actual transfer situation to a certain extent, the evaluation results of only a small number of stations cannot represent the overall situation. Due to the complexity of passengers' subway-bus transfer behavior and the large differences in characteristics in different time periods, it is difficult to conduct on-site tracking surveys, and it is easy to ignore the differences in transfer levels of different rail stations in time and space. The reliability of the evaluation needs to be improved. Summary of the invention

[0023] In order to solve the problem that the reliability of subway-bus transfer service level evaluation in the related art needs to be improved, the first embodiment of the present application provides a method for evaluating transfer service capability, such as Figure 1This is a basic flow chart of the transfer service capability evaluation method provided in this embodiment. The transfer service capability evaluation method includes the following steps:

[0024] Step 101: 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 during a preset period and the signaling data of the target area.

[0025] Specifically, the target site includes a target subway station and at least one surrounding bus station in 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 based on bus card swiping data, and can also be determined in combination with video image monitoring data on the bus, without limitation. Signaling data is a kind of spatiotemporal trajectory big data, which is the spatiotemporal trajectory left by mobile phone users' activities in the mobile communication network. The signaling data of the target area within the preset time period can be obtained through mobile phone operators.

[0026] Step 102: Determine the transfer supply capacity evaluation parameter of the target subway station based on the transfer evaluation index value of the target subway station.

[0027] Specifically, the transfer evaluation index value includes a transfer cost index value and a transfer facility index value.

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

[0029] Specifically, a relationship comparison table corresponding to the evaluation parameters and the evaluation levels can be pre-set and stored in the system, so that the transfer demand evaluation parameters and the transfer supply capacity evaluation parameters can be compared with the relationship comparison table respectively to determine the evaluation levels of the transfer demand evaluation parameters and the transfer supply capacity evaluation parameters, and the transfer service capacity evaluation results between the target subway station and the surrounding bus stations can be generated in combination with each evaluation level.

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

[0031] Specifically, the transfer travel chain of each passenger can be generated according to the ID matching result of the passenger card swiping data (bus card swiping data and subway card swiping data). Figure 2As shown, based on the transfer travel chain, the passengers' transfer time, transfer distance characteristics (front and back sequence transfers) and overall travel distance characteristics (front and back sequence travel) and other information can be determined, and then the proportion of transfer passengers corresponding to different transfer distances can be confirmed by analyzing and counting each transfer travel chain; the scope of the target area is determined according to the transfer distance corresponding to the target proportion of transfer passengers; wherein, the scope of the target area may include a first range corresponding to the transfer demand evaluation and a second range corresponding to the transfer supply evaluation.

[0032] As an example, the target number of transfer passengers is set to 80%. If 80% of the subway-bus transfer passengers transfer at the surrounding bus stops within 800m of the target subway station, and the actual straight-line distance between the alighting location of these transfer passengers and the subway station is greater than 1.5km, the area with the target subway station as the center and a radius of 800m can be determined as the above-mentioned first range, and the area with the target subway station as the center and a radius of 1.5km can be determined as the above-mentioned second range. That is, for the transfer demand evaluation, the number of users whose destination of the transfer travel chain is more than 1.5km away from the subway station can be used for calculation, and for the transfer supply evaluation, the number and frequency of bus stops within 800m from the subway station can be used for evaluation.

[0033] In one implementation of the present embodiment, the step of calculating the transfer demand evaluation parameters of the target subway station based on the passenger flow data of all target stations in the target area during a preset period and the signaling data of the target area includes: 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 the passenger flow data of all target stations in the target area during the preset period; determining the transfer demand rate of the target subway station based on the signaling data of the target area during the preset period; and calculating the transfer demand evaluation parameters of the target subway station based on the number of exits, the actual number of transfers and the transfer demand rate.

[0034] Specifically, the passenger flow data may include bus card swiping data at surrounding bus stations and card swiping data at the target subway station. The actual number of transfer passengers may be determined by analyzing and counting each transfer travel chain.

[0035] Furthermore, in one implementation of the present embodiment, the step of determining the transfer demand rate of the target subway station based on the signaling data of the target area within the preset time period includes: performing travel chain splicing based on the signaling data of the target area within the preset time period, and determining the full travel chain of each traveler passing through the target area; performing stay point identification on each full travel chain, and determining the actual number of transfer passengers between the target subway station and surrounding bus stops and the target number of transfer passengers with transfer needs; wherein, the target number of transfer passengers includes passengers who actually transfer and passengers who have transfer needs but do not actually transfer; and determining the ratio of the target number of transfer passengers to the number of exiting passengers as the transfer demand rate of the target subway station.

[0036] Specifically, the transfer data of the target area can be obtained from operators (for example, China Mobile, China Unicom, China Telecom, etc.). Through the signal and time information of the mobile phone accessing different base stations in the mobile phone signaling data, the user's full travel chain can be identified and extracted. If the mobile phone signaling stays at the same location for more than the preset time threshold (for example, 30 minutes), the location can be determined as a residence point; the base station positioning between the two front and rear residence points can be determined as the travel intermediate chain; among them, the rail station is equipped with a dedicated mobile base station, which can effectively identify the user's rail travel process data. Based on this, the full travel chain of all rail travel users in the mobile phone signaling data can be extracted, and the distance characteristics between the travel start and end points and the subway entry and exit stations can be identified; and then the transfer demand rate of the target area can be converted according to the distance characteristics. In a specific implementation, the proportion of passengers whose destination is more than 1.5 km away from the target subway station among all passengers leaving the surrounding bus station can be determined as the transfer demand rate of the target subway station.

[0037] Further, in one implementation of this embodiment, 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 parameter; the above-mentioned 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 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 between 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 out based on the system preset transfer demand level comparison table (as shown in Table 1).

[0039] Table 1:

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

[0041] In one implementation of the present embodiment, the step of calculating the transfer supply capacity evaluation parameters 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 respectively to obtain a corresponding standardized index value; and calculating the transfer supply capacity evaluation parameters of the target subway station in combination with each standardized index value.

[0042] Specifically, after standardizing each transfer evaluation index, the entropy weight-TOPSIS model can be used to evaluate the subway-bus transfer supply level of the target subway station. That is, the entropy weight method and the TOPSIS method can be combined to efficiently evaluate the transfer supply capacity between the target subway station and the surrounding bus stations.

[0043] Further, in one implementation of this embodiment, the transfer cost index value includes at least one of the average transfer time and the average transfer distance between the 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 of ​​the target bus route; the above-mentioned step of standardizing the transfer evaluation index values ​​of the target subway station to obtain the corresponding standardized index value includes: based on the first calculation formula, standardizing the transfer facility index value of the target subway station 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 a second standardized index value; wherein the second calculation formula is expressed as:

[0046]

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

[0048] Specifically, through standardization, different dimensions and dimensional units of different transfer evaluation indicators can be eliminated. The transfer facility indicator is a positive indicator, and the larger the calculated first standardized indicator value, the better; the transfer cost indicator is a negative indicator, and the smaller the calculated second standardized indicator value, the better.

[0049] Furthermore, in one implementation of the present embodiment, the above-mentioned calculation of the transfer supply capacity evaluation parameter of the target subway station in combination with each standardized indicator value includes: respectively calculating the objective weight of each standardized indicator value; calculating the positive ideal solution distance and the negative ideal solution distance of the transfer evaluation indicator in combination with each standardized indicator value and the corresponding objective weight; 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 (for example, n), the following calculation formula may be used for calculation:

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

[0052]

[0053] D j =1-E j

[0054]

[0055] Among them, 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 above objective weight. The larger the objective weight, the more important the index is:

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

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

[0058] Positive ideal solution distance:

[0059] Negative ideal solution distance:

[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 transfer supply capacity evaluation parameter F:

[0062]

[0063] The larger the F value, the better the transfer supply level. Therefore, the transfer supply capacity evaluation level between the target subway station and the surrounding bus stations can be determined according to the F value. For example, the transfer supply level of each target subway station can be ranked, and the transfer supply capacity evaluation level 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 implementation of the present embodiment, the above-mentioned combination of transfer demand evaluation parameters and each transfer supply capacity evaluation parameter generates a service capacity evaluation result between the target subway station and the surrounding bus stations, including: 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, generating a service capacity evaluation result between the target subway station and the surrounding bus stations, so that the transfer optimization strategy of the target subway station can be determined according to the above-mentioned service capacity evaluation result.

[0068] Through the technical solution of the embodiment of the present application, based on the passenger flow data of all target stations in the target area during a preset period and the signaling data of the target area, the transfer demand evaluation parameters of the target subway station are calculated; wherein the target station includes the target subway station and at least one surrounding bus station in the target area; based on the transfer evaluation index value of the target subway station, the transfer supply capacity evaluation parameters of the target subway station are determined; wherein the transfer evaluation index value includes the transfer cost index value and the transfer facility index value; combined with 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 the solution of the present application, the demand assessment and judgment are carried out in combination with the bus passenger flow data and the signaling data of the target area, and the supply capacity assessment and judgment are carried out in combination with the cost index of the transfer between the target subway station and the surrounding bus stations and the facility index of the target subway station, so as to more truly reflect the level of subway-bus transfer, and provide an effective reference for identifying subway stations with misaligned transfer supply and demand and insufficient supply.

[0073] Step 303: Determine the transfer demand rate of the target subway station based on the signaling data of the target area within a 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 the potential transfer demand and the actual number of transfer passengers to obtain the transfer demand gap parameter of the target subway station.

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

[0077] Specifically, the transfer evaluation index value includes a transfer cost index value and a transfer facility index value; the transfer cost index value includes at least one of the average transfer time and the average transfer distance between the surrounding bus stops 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 stops, the number of all target bus routes corresponding to the surrounding bus stops, and the service area area of ​​the target bus routes.

[0078] Step 307: Calculate the transfer supply capacity evaluation parameters of the target subway station in combination with the standardized index values.

[0079] Step 308: Generate a bus-subway transfer service capacity evaluation result for the target area by combining the potential transfer demand, the transfer demand gap parameter, and the transfer supply capacity evaluation parameter.

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

[0081] It should be understood that the size of the serial number of each step in this embodiment does not mean the order of execution of the steps.
