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.

摘要： 针对复杂轨道网络环境的下出行路径选择问题，传统方法采用理论推算往往与实际偏差较大。基于手机定位信息的出行路径辨识方法，利用手机用户在无线通信网络中产生的信令事件数据，根据其在地铁中的正常位置更新规则得到出行路径，针对信令数据存在缺失的情况，以用户的其他信令事件数据及K短路校核法，对路径的有效性进行检测，进而得到实际出行路径。实测结果表明，用该方法得到的用户出行路径与真实路径偏差较小。。
