A high-precision vehicle trajectory dataset in Shanghai

This is a dataset containing measurement trajectory data from a drone, as well as high-precision trajectory data with an error less than 5cm collected by centimetre-level progressing GNSS receivers. The sample size (number of trajectories of the experimental vehicle inside the intersection) of each measure method is 70, including 27 left-turn trajectories, 27 through trajectories and 16 right-turn trajectories.

本数据集涵盖两类轨迹数据：一类为无人机采集的测量轨迹数据，另一类为厘米级演进型全球导航卫星系统（GNSS）接收机采集的误差小于5厘米的高精度轨迹数据。每种测量方法的样本量（即实验车辆在交叉口内的轨迹条数）均为70条，其中包含27条左转轨迹、27条直行轨迹与16条右转轨迹。
