Travel route identification method of subway passengers based on mobile phone location data

Abstract

Traditional theory-deduced route choice always has large deviation from the actual one in complex rail transit network.The signaling data were collected from the passengers' mobile phone in rail wireless communication network.According to these data,a new travel route identification algorithm was proposed based on normal location update.Meanwhile,concerning the data missing,a repair algorithm was also put forward by using other signaling data of users to deduce their actual travel route by the K shortest paths.And the route validity would be checked to get the actual travel route.Finally,typical application in Beijing rail transit network was selected to validate this algorithm.The application results show that the algorithm has a good performance in illustrating the actual travelers' travel behaviors.
