摘　　要：为了便于分析、研究城市微观混合交通特性,把视频分析系统引入到微观交通分析领域。分析了视频分析系统应用于微观交通特性分析的适用性,以北京市平乐园路口为例,对高峰时段的非机动车道混合交通特性进行了分析,通过视频分析结果可以发现,非机动车道混合流具有明显的2阶段性质,在第1个阶段以一个团体形式通过,第2个阶段则是随机通过路口。To analyze the microscopic traffic characteristic, this paper applies the technique of video analysis to the microscopic traffic. First, the applicability of video analysis system in the microscopic traffic was analyzed. By taking Pingleyuan Crossing in Beijing as an example, the mixed traffic flow of the crosswalk of the peak hour was analyzed. The result of the video analysis shows that the mixed traffic flow of the crosswalk has the characteristic of two processes. In the first process the mixed traffic flow goes through the crossing as a group, and in the second process the mixed traffic flow goes through the crossing stochastically.
