前置虚拟作业区对高速公路施工路段交通运行的影响研究

Research on Influence of Front Virtual Work Zone on the Traffic Operation on Expressway Construction Sections

提出了一种不同于传统作业区交通组织方案的全新的交通组织方案,研究了高速公路作业区上游前置虚拟作业区对交通运行产生的影响。高速公路作业区上游设置虚拟作业区,目的在于强制部分车辆在上游转弯,降低它们的速度,防止侵略性驾驶行为的发生。通过方案比选,基于VISSIM微观交通流仿真技术得到:设置虚拟作业区在通行效率和速度一致性两方面均优于不设置虚拟作业区,是一种值得推广的作业区空间布局方式。

In this paper a new traffic organization plan which is different from traditional schemes is proposed. The influence of front virtual work zone in the upstream of expressway work zone on the traffic operation is studied. The front virtual work zone is set up in the upstream of the expressway work zone, aiming at forcing part of vehicles to turn in the upper stream, reduce their speed and prevent aggressive driving behaviors. In this paper, through comparisons of schemes, based on VISSIM microscopic traffic flow simulation technology, it is drawn that setting the virtual work zone in the upstream of the freeway is superior than not setting virtual work zone in terms of traffic efficiency and speed consistency, which is agood spatial layout of work zone and worthy to be popularized.
