多路交叉口分散交通组织方法研究

Research on Dispersed Traffic Organization Method of Multi-Intersection

针对多路交叉口交通转向数量多、总交通流量大的特点,提出了将一个大交叉口分解为数个微型交叉口进行分散组织的方法,给出了转向交通流线组织、信号灯协调控制、微型交叉口之间连接道路设计的方法。以五路、六路相交道路为例,给出了交叉口信号配时、延误时间、连接道路长度及渠化车道数等计算参数。可弥补五路及以上交叉口设计方法的缺少,为类似项目提供借鉴。

The multi-intersection has many traffic diversions and large traffic flow. It is divided into several micro-inter-section to organize traffic dispersedly. The method of steering traffic streamline organization, signal coordinated controland the connected road between micro-intersections is proposed. Taking five and six road intersection as examples, theparameters of signal timing, delay times, the length of connected road and the number of channelization lanes are given.It can make up for the lack of design methods for multi-intersection of five or more roads, and provide reference for similarprojects.
