摘要
在城市道路网中,平面交叉口是城市道路通行能力和交通安全的瓶颈。由于社会经济、文化背景、道路环境等的不同,不同地区的交通活动表现出不同的行为特征。本文采用视频技术和人工观测技术,研究了重庆市机动车在市政道路信号平面交叉口时的交通特征,为交叉口立体空间设计和信号配时优化提供了基础数据。
In urban road network, the intersections are bottlenecks of capacity and traffic safety. Because of the different socio-economic, cultural backgrounds, road environment, the transport activities showed different behavioral characteristics in different regions. In this paper, we used video technology and artificial observation techniques to study the traffic characteristics of motor vehicle at Signalized Intersections in Chongqing, which can provide basic date for three-dimensional design and signal matching of intersections.
