| 摘 要： | 提出并实现了一种基于手机定位轨迹数据的出行行程识别方法.通过速度对轨迹点进行划分,将低于一定速度阈值以下的轨迹点合并为候选停留位置,再利用距离阈值和时间阈值对候选停留位置进行合并,从而确定出真正的停留点,继而自动统计出行次数和出行时间.该方法解决了手机定位数据的定位漂移和抖动的问题,行程识别精度高,识别结果可为交通规划工作提供相关数据,并具有比传统交通调查方法更低的成本和更短的数据更新周期.

| Abstract: | A method to identify trip based on the mobile phone positioning data is proposed and implemented.According to their speed the track points are divided into two types,and these lower than a certain speed are merged to candidate stay position.In order to determine these real stay point,the distance threshold and time threshold are used to merge stay position,and then automatic statistics of travel times and travel time is followed.The method resolve the drift and jitter problem of mobile phone positioning data,and has high identification accuracy.The recognition results can provide relevant data for transportation planning,and has lower cost and shorter data update cycle than traditional traffic survey methods. |
