高架桥下交叉路口交通放行时间和空间资源的综合利用

An Analysis and Utilization for the Time-Space Resource at an Intersection with a Wider Separation Band

本文对高架桥下交叉口的时空资源进行了分析综合利用，提出了一种多相位半幅路权系统。该系统通过对高架桥下交叉口路面的道路渠划，把各种交通流通过交叉口路面的道路划分为上下两个半幅路面，并使半幅车道数大于进口处的车道数；由信号机控制信号灯以半幅路面路权为单位放行交通流，巧妙安排相位和相位顺序；在整幅放行前的前半幅路权放行时，可以使车流缓慢、安全地分流在较多的放行车道上排成车队形式；待后半幅路权放行时，以多路车队形式集中通过路口。缩短过路时间，提高通行效率，充分利用时间和空间资源。

In this paper, an analysis and utilization for the time-space resource at an intersection with a wider separation band is given. In an half-roadway right traffic control system at an intersection with a wider separation is given. In this system, different roadway for different traffic flow could be channelized at the intersection, the intersection corresponding the wider separation band. The roadway could be separated two half-roadway： front-way and behind-way. Some traffic flows could be permitted to through the whole roadway half-roadway by half-roadway by given half-roadway right from the half-roadway traffic signal to be turn on one by one. By this method, the intersection traffic control could be designed carefully, the time-space resource utility could be double. The ability of through the intersection and the city road network could be double too.
