| Abstract: | Due to mixed traffic in most Chinese cities,it's necessary to research the characteristics of mixed traffic in China.The data collection was based on a trajectory capture system including video taping,video processing,trajectory capture and coordinate transformation.Data mining and regressing analysis is employed to figure out the position and speed distribution of traffic entities in mixed traffic.The interactions between traffic entities are discussed. |

| Keywords: | trajectories capture mixed traffic position speed |
