Description

Technical Field

[0001] The present invention relates to a solution for correcting the clearing algorithm in the urban rail transit clearing center system. Background Art

[0002] Currently, most of the clearing algorithms applied in the urban rail transit network clearing system are based on a two-stage, double-proportion scheme; this scheme is based on an exhaustive search of the passenger's travel path, combined with several selected key parameters such as the total travel time, the number of transfers, the transfer walking distance, and then applying a normal distribution model to generate the theoretical clearing ratio between each path, and then combining the questionnaire survey data to adjust the algorithm parameters to fit the questionnaire statistical data.

[0003] For the subsequent inspection and adjustment of the clearing algorithm, generally consider methods of other technologies, such as the signal density based on communication base stations, and dedicated / shared sensors to count people; due to other defects, it is not widely used at present. For example, firstly, the technical methods adopted cannot be closely associated with the passenger's travel itinerary in the AFC system (Automatic Fare Collection System), and there are relatively large disturbing factors in sampling; secondly, the construction investment cost is relatively large, invested once in a project manner, and it is difficult to implement subsequently, and the investment cost has no sustainability and obvious cost-effectiveness; therefore, the recognition of rail transit operators is limited.

[0004] With the progress of technology and the development of the economy, the business of the AFC system is also evolving. The ride vouchers in most cities have been converted to real-name based on mobile personal terminals, and most rail transit operators have also introduced and used mobile applications such as mini-programs and APPs. Based on the positioning technology of mobile signals, the large-scale promotion of ride QR codes has also well cultivated the usage habits of passengers. Therefore, the conditions for proposing and applying this solution are available. Summary of the Invention

[0005] The main purpose of the present invention is to provide a solution for correcting the clearing algorithm of the urban rail transit clearing center system, aiming to solve the credibility test and subsequent adjustment problems of the current clearing algorithm.

[0006] To achieve the above object, the present invention provides a solution for correcting the clearing algorithm of the urban rail transit clearing center system, and the solution includes the following steps:

[0007] Before opening, conduct a passenger travel questionnaire survey, and generate the initial clearing algorithm path and clearing ratio in combination with the network topology;

[0008] Push notifications to each real-name passenger who checks in through the APP, suggesting that the passenger sign in at the transfer station, and giving points or designated rewards to the signed-in passengers in combination with subway commerce. The APP sign-in information includes the passenger information and the information of the sign-in station;

[0009] For each real-name passenger who has exited the station and whose travel route involves transfers, remind the passenger to register the transfer station, and give points or designated rewards to the registered passengers in combination with subway commerce. The APP registration information includes the passenger information and the information of the sign-in station;

[0010] Compose the travel route information of the passenger based on the entry information, sign-in / registration information, and exit information;

[0011] Conduct a rationality review of the composed travel route information and eliminate the unreasonable travel route information;

[0012] Compare the obtained travel route information of the trip with the travel routes for clearing fares of the existing clearing algorithm, and correct the travel route information of the clearing algorithm;

[0013] Regularly count and summarize the passenger flow ratio among the obtained travel route information of the trip; calculate the sampling rate of the transfer passenger flow based on the line network passenger flow, conduct a confidence evaluation of the statistical data of this round, and use the statistical ratio of the travel routes with the confidence reaching the threshold to correct the passenger flow distribution ratio and revenue distribution ratio among the travel routes for clearing fares of the existing clearing algorithm, and apply it to the clearing process;

[0014] Initiate various correction works regularly according to the line network construction situation, train operation situation, urban planning layout, and construction change situation to ensure the timely applicability of the clearing algorithm path and the clearing algorithm.

[0015] Before opening, conduct a passenger travel questionnaire survey, and generate the initial clearing algorithm path and clearing ratio in combination with the line network topology. The content includes:

[0016] This is the current common method for generating the clearing algorithm. First, according to the line network topology, use the exhaustive or graph theory method to find all transfer paths between all trips in the line network; then select the clearing influence factors, generally the total travel time, the number of transfers, and the transfer walking distance, and then apply the normal distribution model to generate the theoretical clearing ratio between each path. Then, combine the questionnaire survey data to adjust the parameters of the normal distribution model to fit the questionnaire statistical data.

[0017] The content of pushing notifications to each real-name passenger who checks in through the APP, suggesting that the passenger sign in at the transfer station, and giving points or designated rewards to the signed-in passengers in combination with subway commerce. The APP sign-in information includes the passenger information and the information of the sign-in station includes:

[0018] When passengers use the APP to check in and board the train with real names, a notification is pushed to the passenger APP, informing passengers that there are preferential activities for signing in at transfer stations. The preferential activities generally give points or specified rewards to passengers who sign in in combination with subway commerce.

[0019] The APP sign-in information includes passenger information and information about the sign-in station. The implementation methods include providing multiple methods for passengers to actively report transfer station information, including: Method 1, posting sign-in QR codes on advertisements and passenger information screens at prominent positions in the concourse and platform of transfer stations for transfer passengers to scan and sign in, and associating preferential information; Method 2, providing location-based sign-in services on the passenger APP; when passengers actually sign in at transfer stations, obtaining the passenger coordinate location or the station information scanned by the QR code, and generating and uploading the sign-in information by the APP.

[0020] In particular, the above sign-in information is collected in real time with real names, has a certain degree of credibility, and can truly reflect the actual transfer stations of passengers.

[0021] For each real-name passenger who has exited the station and whose travel route involves transfers, remind the passenger to register the transfer station, and give points or specified rewards to the registered passengers in combination with subway commerce. The APP registration information includes passenger information and information about the sign-in station. The content includes:

[0022] After the passenger exits the station, judge whether there is a transfer according to the travel itinerary information. If there is a transfer in the travel itinerary information, push a notification to inform the passenger that there are preferential activities for registering the transfer station; guide the passenger to register the transfer station information on the APP. When the passenger registers the transfer station information after exiting the station, the APP generates and uploads the registration information, and the APP registration information includes passenger information and information about the transfer station.

[0023] In particular, the credibility of the registration information is lower than that of the sign-in information, and there is a situation where passengers may register falsely at will. Subsequently, it is necessary to conduct data review in combination with the passenger's travel information to remove unreasonable registration information.

[0024] The travel route information of passengers is composed of the inbound information, sign-in / registration information, and outbound information; the content includes:

[0025] Obtain the travel itinerary information according to the inbound and outbound information of passengers saved in the automatic fare collection system, and then obtain the sign-in / registration information from the real-name information of passengers in the inbound and outbound information, so as to obtain the travel route information of the passenger.

[0026] In particular, when the road network scale is large, passengers may need to transfer multiple times, but they will not sign in every time they transfer. Therefore, it is necessary to combine the travel route information obtained by the existing fare clearing algorithm, the passenger's historical sign-in information and historical travel route information to obtain the travel route information of the passenger's current trip.

[0027] Perform a rationality review on the travel itinerary path information and eliminate unreasonable travel itinerary path information; the content includes:

[0028] Adopt the travel itinerary path information composed of check-in information, and conduct a rationality review on the travel itinerary path information composed of registration information. During the rationality review, make a matching judgment based on the passenger's entry information, exit information, and registration information. Judge the rationality of the registration information for this trip from aspects such as the transfer stations included in the matching path, the total travel time, and the passenger's personal habits. Do not adopt the travel itinerary path information that fails to pass the review.

[0029] Compare the obtained travel itinerary path information with the cleared travel paths of the existing clearing algorithm to correct the travel path information of the clearing algorithm; the content includes:

[0030] According to the cleared travel paths of the existing clearing algorithm, distinguish between the travel itineraries of passengers who do not need to transfer and those who need to transfer. For the travel itineraries of passengers who need to transfer, count the paths composed of the transfer stations given by the existing clearing algorithm, the paths composed of the stations included in the passenger's check-in information, and the paths composed of the stations included in the passenger's registration information. Obtain the union of the three as the transfer paths between all travel itineraries.

[0031] In particular, the transfer paths between the latter two travel itineraries are obtained through actual sampling and have a definite credibility, which has a corrective effect on the paths obtained by the initial clearing algorithm through theoretical calculations based on the line network topology and the normal distribution model.

[0032] Regularly statistically summarize the passenger flow ratios among the obtained travel itinerary path information; calculate the sampling rate of the transfer passenger flow based on the line network passenger flow, conduct a confidence evaluation of the statistical data for this round, and use the statistical ratio of the travel paths with a confidence level reaching the set threshold to correct the passenger flow distribution ratio and revenue distribution ratio between the cleared travel paths of the existing clearing algorithm, and apply them to the clearing process; the content includes:

[0033] For the travel itineraries of passengers who need to transfer, count the total number of transfer passenger flows, the number of transfer passenger flows on each path with check-in information, and the number of transfer passenger flows on each path with registration information according to the obtained travel itinerary paths. Evaluate the confidence level of the sampled information based on the ratio of the check-in / registration passenger flow to the total passenger flow. If the sampled passenger flow ratio reaches the set confidence threshold, calculate the ratio of the passenger flow on each path to the transfer passenger flow between travel itineraries according to the statistical data on each path of the sampled data, and use it as the correction data for the clearing ratio this time, which is applied to subsequent passenger flow clearing and revenue clearing; if the sampled passenger flow ratio does not reach the set confidence threshold, refer to the transfer paths between sampled travel itineraries and the data ratio of the sampled passenger flow between each path, adjust the factors for calculating the clearing travel itinerary paths and clearing ratios of the existing algorithm, and fit and generate a new ratio for subsequent clearing.

[0034] According to the line network construction situation, train operation situation, urban planning layout, and construction change situation, initiate various correction works regularly to ensure the timely applicability of the clearing paths and clearing ratios of the clearing algorithm; the content includes:

[0035] In the case of the opening and operation of new lines or new stations, the adjustment of the train operation diagram, and the completion and commissioning of new residential areas or commercial areas near stations, initiate various correction works in a timely manner; and during the operation period, in combination with the operation of subway commerce, continuously or regularly initiate various correction works to test the rationality of the clearing paths and clearing ratios in the clearing system and carry out corrections.

[0036] The solution to the clearing algorithm correction problem proposed by the clearing center system of urban rail transit of the present invention, in response to the current business transformation situation of the AFC system and combined with the development and application of the current subway TOD construction model (Transit-Oriented Development), can comprehensively achieve multiple objectives such as business expansion, passenger flow investigation, and revenue clearing. Brief Description of the Drawings

[0037] Figure 1 It is a schematic diagram of obtaining the clearing travel itinerary paths, passenger flow clearing ratio, revenue clearing ratio, and application of the clearing ratio through the operation of the clearing algorithm applied in the current rail transit network clearing system involved in the embodiment solution of the present invention;

[0038] Figure 2 It is a schematic flowchart of the embodiment of the present invention.

[0039] The realization, functional characteristics, and advantages of the objectives of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiments

[0040] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] like Figure 1 As shown, Figure 1 It is a schematic diagram of the clearing algorithm used in the current rail transit network clearing system involved in the embodiment of the present invention, for obtaining the clearing travel route, passenger flow clearing ratio, revenue clearing ratio and the application of the clearing ratio. Figure 1 The content is a prerequisite for the implementation of the present invention and is only briefly explained here.

[0042] like Figure 1 As shown, Figure 1 The path damping described in S10 includes a variety of influencing factors, and the most commonly used ones are the shortest path (shortest total travel time), the number of transfers, and the transfer distance. The travel path search algorithm generally sets the maximum number of transfers to reduce the time required for the algorithm to run. The choice of the travel path of the clearing algorithm will present different results under different conditions.

[0043] like Figure 1 The parameter selection of the normal distribution function described in S11 will affect the obtained results. Generally, the actual route selection intention is obtained by relying on the questionnaire survey before opening. The principle of selecting parameters is that the passenger flow distribution result obtained by calculation should fit the distribution of the questionnaire survey results as much as possible.

[0044] like Figure 1 The travel route parameters described in S11 may be the total distance or number of stations for each route, and the revenue is distributed among the routes (operators) according to the proportion of the selected parameters.

[0045] like Figure 1 The clearing algorithm described in S1 focuses on the calculation of the clearing ratio of freight charges, while other charges, such as service charges, are based on the agreement between rail transit automatic ticket vending and checking operators and are cleared according to the number of stations or other parameters.

[0046] like Figure 1 The clearing application process described in S2 is a process of allocating the passenger flow and revenue of barrier-free transfer to each line and each operator based on the passenger flow clearing ratio and the revenue clearing ratio.

[0047] Those skilled in the art will understand that Figure 1 The clearing algorithm shown in the figure generates a clearing ratio and applies the clearing ratio to perform clearing. The process is only used to illustrate the processing process of a general rail transit clearing system, and is not used to limit the method and application process of generating the initial clearing ratio involved in the present invention.

[0048] Reference Figure 2 The embodiment of the present invention provides a solution for correcting the sorting algorithm of the urban rail transit sorting center system, and the solution includes:

[0049] Step S30, the passenger enters the station with real-name authentication through the APP. Here, the APP is a general term for mobile applications, which can be mini-programs or independent applications of each rail transit company.

[0050] Specifically, the APP has multiple functions and is a client that combines customers, users, and accounts, and requires real-name registration; the associated functions of the APP generally include supporting post-payment ride codes, online purchase of virtual tickets, binding account payments, and itinerary inquiries; the APP runs on personal mobile terminals, which generally have the functions of QR code display, QR code scanning, and face photography.

[0051] Specifically, the passenger's entry into the station here refers to the process in which the passenger shows the boarding pass and passes through the automatic ticket inspection equipment at the entrance to enter the paid area of the rail transit. The automatic ticket inspection equipment obtains the information of the boarding pass during this process, combines the information of the station where the equipment is installed and the time when the ticket inspection occurs, and organizes the entry information to be uploaded to the rail transit clearing center through the automatic fare collection system. The boarding pass shown by the APP for the passenger contains the identification information of the passenger.

[0052] Step S31, push a notification to the passenger APP to inform the passenger that there is a preferential activity for signing in at the transfer station on the APP. Here, the notification push is an active operation of the APP background management system and requires the APP to implement receiving and displaying.

[0053] Specifically, since it is impossible to determine the passenger's travel destination when the passenger enters the station, and further, it is also impossible to determine whether the passenger's itinerary this time requires a transfer, so the message push here is for all passengers who enter the station and pass the ticket inspection through the APP. However, passengers are not obliged to actively sign in at the transfer station. It is necessary to attract passengers to participate in the signing in through preferential methods. The preferential activity can be combined with subway commerce or can be used as the cost for the inspection and correction of the clearing algorithm, and is approved for payment processing.

[0054] Step S32, the passenger signs in at the transfer station, and the APP scans the QR code or locates by coordinates.

[0055] Specifically, at the transfer station, multiple methods are adopted for passengers to actively sign in and report the transfer station information. For example: Method 1, post advertisements at prominent positions in the concourse / platform of the transfer station, such as on the media like the passenger information screen, provide a signing-in QR code for transfer passengers to use the APP to scan and sign in, and associate preferential information on the APP signing-in page; the signing-in QR code contains the station information of this transfer station; Method 2, provide a location-based signing-in page on the passenger APP, obtain the passenger's location information when the passenger signs in, and display the associated preferential information; the APP background management system obtains the station information where the passenger signs in according to the passenger's location information. When the passenger actually signs in at the transfer station, the APP generates and uploads the signing-in information.

[0056] Specifically, when passengers sign in using location information in this embodiment, there are cases where the actual location is not at the transfer station, or even not within the rail transit line. Therefore, it is necessary to associate the sign-in information with the ticket inspection information of the AFC system subsequently to screen out unreasonable and messy data. The sign-in information contains the identification information of the passengers, which can identify the source of the location information, and passengers with false sign-in information will be marked.

[0057] Step S33, when the passenger exits the station, determine whether there is a transfer according to the travel itinerary. If there is a transfer, push a notification to inform the passenger that there are preferential activities at the registered transfer station.

[0058] Specifically, the passenger exiting the station here refers to the process in which the passenger shows the travel voucher and passes through the outbound automatic ticket inspection equipment to leave the paid area of the rail transit. The outbound automatic ticket inspection equipment obtains the information of the travel voucher during this process, and combines the information of the station where the equipment is installed and the time of ticket inspection to organize the outbound information and upload it to the clearing center system through the AFC system. The travel voucher shown in the APP contains the identification information of the passenger.

[0059] The preferential notification information pushed here is the same as the preferential notification information described in S31.

[0060] Particularly, the determination of whether there is a transfer according to the travel itinerary here has various different situations in various rail transit network topologies. Here, the travel itinerary with only one path is determined as a travel itinerary without transfer.

[0061] Step S34, the passenger registers the transfer station.

[0062] Specifically, the passenger enters the operation interface on the APP, selects the transfer stations passed by during this trip and submits them, and the APP generates and uploads the registration information.

[0063] So far, the process of passenger investigation is completed. The correction process of this embodiment will be described below.

[0064] Step S40, match the AFC inbound transaction (S30), AFC outbound transaction (S33), sign-in transaction (S32) / registration transaction (S34) according to the passenger information to form the passenger travel path information.

[0065] Specifically, the AFC inbound transaction (S30) and AFC outbound transaction (S33) here are both travel itinerary information possessed by the AFC system itself. Under the condition of barrier-free transfer, it is impossible to judge the actual travel path of the passenger when there are multiple reachable paths.

[0066] Particularly, in this solution, in the case of having a sign-in transaction (S32) / registration transaction (S34), according to the information of the APP passenger, the actual travel path of the passenger can be matched.

[0067] Specifically, based on the information of the APP passenger, the above related information is searched to form a data set, and then the entry site included in the AFC entry transaction (S30) is used as the starting point, and it is determined one by one whether the sites included in the check-in transaction (S32) / registration transaction (S34) are on the path to the sites included in the AFC exit transaction (S33), and they are sorted in the order passed. After the sorting is completed, preliminary itinerary path information is formed.

[0068] In particular, in a travel itinerary that includes multiple transfers, the sign-in transaction (S32) / registration transaction (S34) may only include some of the intermediate transfer stations. If the sign-in transaction (S32) / registration transaction (S34) can determine the complete path, it is necessary to complete it based on the above preliminary itinerary path information. If the sign-in transaction (S32) / registration transaction (S34) cannot confirm the complete path, it is completed according to the optimal path in the clearing path of the existing clearing algorithm.

[0069] Step S41, judging the rationality of the travel route information in S40, and eliminating unreasonable travel itinerary transfer routes (false registration of passengers or low-probability passenger behavior).

[0070] Specifically, in the data set of step S40, if it is determined that the site information included in the check-in transaction (S32) / registration transaction (S34) is not on the path to the site included in the AFC outbound transaction (S33), or the site in the registration transaction (S34) cannot constitute this trip, it is marked as false information and will not be accepted.

[0071] In particular, there are cases where passengers are unfamiliar with the subway network or choose less efficient or multiple-turn routes just to enjoy the scenery of the subway stations, and sign in completely each time; such information will also be treated as false information here.

[0072] Step S42, adjusting the travel path selected by the existing clearing algorithm, adding a reasonable new travel transfer path in S41, and marking the transfer station group of the travel path.

[0073] Specifically, the travel itinerary transfer path information obtained in step S41 and the travel itinerary clearing path selected by the existing clearing algorithm are combined into a data set as a new travel itinerary path set; the travel itinerary path set includes new paths and no new paths.

[0074] Step S43, counting the proportion of passengers between the marked transfer paths of each travel itinerary.

[0075] Specifically, for the travel itinerary information without check-in transactions (S32) / registration transactions (S34) or the travel itinerary information that is not credible, the clearing path ratio obtained by applying the existing clearing algorithm is used for clearing operations to obtain the cleared passenger flow data for each travel itinerary path; for the travel itinerary information with check-in transactions (S32) / registration transactions (S34), the passenger flow data for each travel itinerary path is statistically calculated based on the data processed in step S42; the passenger flow information of passengers without check-in / registration is superimposed to obtain the aggregated passenger flow statistical data.

[0076] Furthermore, the aggregated passenger flow statistical data for each travel itinerary path is calculated with the total passenger flow of this travel itinerary to obtain the proportion of passengers among the transfer paths of each travel itinerary.

[0077] Step S44, perform confidence judgment based on the proportion of passenger flow. Compare the proportion with a set threshold in the confidence level in the statistics of S43 with the passenger flow distribution ratio of the algorithm, and adjust the clearing algorithm parameters to correct the passenger flow clearing ratio.

[0078] Specifically, calculate the statistical data of the travel itinerary information with check-in transactions (S32) / registration transactions (S34) and the cleared passenger flow data of the travel itinerary information without check-in transactions (S32) / registration transactions (S34) described in step S43 to obtain the ratio of the sampled passenger path information among the paths of this travel itinerary. Use this ratio as the confidence level. If this ratio reaches or exceeds the set threshold, then use the operation result of step S43 as the clearing ratio for subsequent clearing; if this ratio does not reach or exceed the set threshold, then output this confidence level, analyze the reasons, and formulate measures to strengthen the sampling guidance for the next step.

[0079] Step S45, correct the clearing ratio of revenue distribution.

[0080] Specifically, use the travel itinerary transfer paths and the passenger flow clearing ratios among the paths obtained in steps S40~S44, combined with the parameters of revenue clearing, to recalculate and correct the revenue clearing ratio for subsequent use in clearing operations.
