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.本数据集包含中国深圳市中心城区道路路网（LINKS）的交叉口节点（NODES）坐标。在SPEEDS数据文件中，存储了依托地图匹配算法，将约20000辆出租车的GPS轨迹点与该道路路网完成匹配后计算得到的、每5分钟更新一次的路段空间平均车速估算值。本次数据集覆盖的日期为2011年9月7日、8日及9日。
