Passenger Path Identification In Subway Stations Based On WIFI Probe

Along with the advance of society,urban rail transit network of transport capacity is stronger,the residents’ travel gave us a great convenience,and for urban rail transit passenger station go bad behavior in the network environment,traditional methods because of the lack of time and space dimensions of detailed data,the results and the actual situation there is a deviation.However,in the positioning service,the most extensive satellite positioning system is suspended.Due to the factors such as blocking and interference of signals,the positioning application in subway stations is greatly restricted,and accurate location information cannot be obtained,so it is difficult to meet people’s needs.In this paper,a new communication device--WIFI probe is used to locate passengers in subway stations,and the method of route identification of passengers in subway stations based on WIFI probe data is deeply studied.First of all,the key nodes of passengers’ travel paths in the station are analyzed,and the travel paths in the station are predicted based on the key nodes passed by passengers.The indoor positioning algorithm is used to confirm the actual positions of passengers at different times so as to correct the errors of passengers’ paths and improve the accuracy of passengers’ paths in the station.The results of this paper aim to lay the theoretical method and method foundation for subway station passenger path identification,and provide theoretical and technical support for the analysis of urban rail transit passenger flow and the runoff density of each road.
