基于通勤轨迹的潮汐交通拥堵路段识别与分析

提出一种基于通勤轨迹数据,结合地图匹配算法和潮汐交通特征计算的潮汐交通拥堵识别方法,轨迹数据具有时间和空间上的连续性,而道路流量受单条轨迹数据的缺失影响比较小.潮汐路段空间分布结果显示武汉市都市发展区的潮汐交通分布在环线之间的连接路、跨江通道的出入口路段以及重要交通枢纽附近.武汉市目前潮汐路段相对较多而可变车道数量较少...

Identification and Analysis of Tidal Congested Section Based on Commuter Trajectory

In this paper,we proposed a tidal traffic congestion identification method based on commuter trajectory data,which combined with map matching algorithm and tidal traffic feature calculation.The trajectory data has the continuity in time and space,and the road low is less affected by the lack of single track data.The results of spatial distribution of tidal sections show that the tidal traffic in Wuhan urban development zone is distributed in the connecting roads between loop roads,the entrance and exit sections of river crossing channels and the vicinity of important transportation hubs.At present,there are many tidal roads in Wuhan,but the number of variable lanes is relatively small.The identification results of this study are helpful for the relevant departments to plan the specific location of tidal lanes and predict the possible tidal congestion sections.
