基于运动轨迹采集的混合交通特性研究

Research of Mixed Traffic Based on Trajectories Capture

为研究中国城市交通的混合交通特性,通过视频采集、视频处理、运动轨迹提取和坐标转化等一系列处理手段,提出了获取混合交通流中各类运动实体的轨迹线的基本方法.通过对轨迹数据的数据挖掘和回归分析,研究混合交通流中各类运动实体的空间位置和速度分布,分析了混合交通流中机动车和非机动车相互影响的成因和表现.

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 video processing, trajectory capture and coordinate a trajectory capture system including video taping, 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.
