高架桥下交叉路口交通放行时间和空间资源的综合利用

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。

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

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.
