Shenzhen_whole_day_Speeds

The data are composed by the coordinates of the intersection (NODES) of the road map (LINKS) of the downtown of Shenzhen, China. In the file SPEEDS there are the estimation of the space-mean links speed every 5 mins computed after a map matching algorithm of available of about 20,000 taxis' GPS points with the road map. The day taken in consideration are the 7th, 8th and 9th September 2011.

本数据集由中国深圳市中心城区道路路网（LINKS）的交叉口节点（NODES）坐标组成。在SPEEDS数据文件中，存储了通过对约20000辆可用出租车的GPS点位与该道路路网执行地图匹配算法后，计算得到的每5分钟级别的路段空间平均车速估计值。本次研究采用的日期为2011年9月7日、8日及9日。
