On Regional Rail Transit Travel Planning System Based On Passenger Flow Prediction

The travel planning system is an important reference tool for passengers to choose a travel route.A safe and efficient travel plan can improve ride safety and travel efficiency of passengers,and improve the service level of the rail transit system.Aiming at the lack of interaction research between travel planning information and passenger flow prediction information in existing systems and related research,a new regional rail transit travel planning system based on passenger flow prediction is studied and implemented in this thesis.This system makes short-term prediction of passenger flow based on individual travel planning information.The passenger flow prediction results are used to provide support for subsequent passenger travel planning.Firstly,the subjects in the rail transit system,the interrelationships between the subjects,and the respective needs of the subjects are analyzed,and then the overall functional requirements of the regional rail transit travel planning system are proposed to clarify the goals of the system.Secondly,the interactive relationship and interactive information between the system and the rail transportation companies and passengers are analyzed in this thesis,and then the design of system architecture,core module and interface are completed.In the core module design,the travel planning algorithm is designed by improving the existing time-expanded model and combining Dijkstra algorithm,the passenger induction mechanism is designed through the passenger score mechanism,and passenger flow prediction algorithm is designed based on the estimation of passenger trustworthy rate and application coverage rate.After that,the detailed design of each module in the system and the implementation of the prototype system are completed based on the object-oriented design method in this thesis.Finally,based on the railway network of the Chengdu-Chongqing area,the rail transit system simulation test environment including the basic railway network,trains and passengers is designed and developed in this thesis.The feasibility of the prototype system and the effectiveness of the algorithm are preliminary verified through simulation test environment.The regional rail transit travel planning system based on the interactive mechanism of travel planning information and passenger flow prediction information is researched and initially implemented in this thesis.The design of system architecture,core module and related algorithm are completed,and the prototype system and simulation test environment are realized.Finally,the feasibility and effectiveness of the system and related algorithms are preliminarily verified.
