Vehicle trajectory
We have selected three intersections within Xi'an, Shaanxi Province, China for data collection. These include the intersection of Taibai South Road and Keji Road, the intersection of Chang'an North Road and Yanta West Road, and the intersection of Yanta North Road and Youyi Road. The UAV for the purpose of video data collection is employed to investigate intersections, with a high-definition video resolution of 4096 * 2160. The spatiotemporal position information of target vehicles was tracked and labeled using Datafromsky software.

The extraction and construction of high-precision and long-distance vehicle trajectory data and microscopic traffic flow characteristics are critical for traffic safety studies. Current research typically relies on a limited number of datasets which suffer from vehicle detection inaccuracy and limitation of the coverage area. Therefore, we establish a high-precision and long-distance vehicle trajectory dataset of urban scenarios, which is also named as WUT-NGSIM.
