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。
Proposed a new traffic organization scheme different from the traffic organization scheme of the traditional operation area and studied the impact of the front virtual working area in the upper reaches of the expressway on the traffic operation. The virtual work area is set up upstream of the expressway work area in order to force some of the vehicles to make turns in the upper reaches to reduce their speed and prevent aggressive driving behavior. Based on the VISSIM micro traffic flow simulation technology, this paper shows that setting the virtual work area is better than not setting the virtual work area in terms of traffic efficiency and speed consistency, which is worth promoting a space layout of the work area.
