广州市内环路增槎路放射线合流段分车道信号控制设计

Design of Split-lane Signal Control for the Zengcha Radial Lane of Guangzhou Inner Ring Expressway

随着城市社会经济的快速发展,交通拥堵已成为大中型城市发展过程不可避免的难题,其中快速路合流段的拥堵问题越来越凸显,严重制约着城市路网的整体运行效率。为解决快速路合流段通行效率低下、交通秩序混乱等问题,提出在快速路匝道合流位置设置分车道信号控制的措施,针对路段内早晚高峰的流量特征,实行不同的信号控制方案,充分挖掘有限的道路空间,从而保证合流段整体的运行效率与交通秩序,并以广州市内环路增槎路放射线为例,介绍分车道信号控制作为快速路合流段拥堵的治理方法在实际应用过程中的实施条件、设计方案与实施效果。

With the rapid growth of economy and society,traffic congestion has become an inevitable problem during the development of large and medium-sized cities.The problem of traffic congestion at the on-ramp junction of city expressway is more and more prominent,which seriously restricts the overall operation of road network.In order to solve the problems like traffic inefficiency and disorder at the on-ramp junction of expressways,this paper puts forward the treatment measures of using split-lane signal control.According to the flow characteristics of morning and evening peak in the section,different signal control schemes are implemented to fully excavate the limited road space,so as to improve the overall operation efficiency and traffic safety at the junction.Taking the Zengcha Radial Lane of Guangzhou Inner Ring Expressway as an example,this paper introduces the implementation conditions,design scheme and implementation effect of split-lane signal control as a traffic congestion treatment at the on-ramp junction of expressway.
