基于交通仿真条件下多功能车道设置的必要性分析

选取天津市快速环路的路段为仿真背景,在主线为双向6车道和8车道时,分别进行多功能车道设置的必要性分析。采用VISSIM微观仿真软件,在主路车道数相同时,将设与不设多功能车道两种情况下事故车辆每车停车时间均取为15 min,仿真每种情况在事故停车率分别为0.05%、0.1%下的通行能力及延误。通过比较设置与不设置多功能车道在车辆紧急停靠时主线的通行能力及其它车辆延误,来分析多功能车道设置的必要性。

Analysis on Necessity of Installing Multi-function Lane Based on Traffic Simulation

Based on the simulation of the express ring road sections in Tianjin,the article analyzes the necessities of installing the multi-function lanes in the main line separately with 6 double-way lanes and 8 double-way lanes.VISSIM microcosmic simulation software is used to simulate the traffic capacity and delay of each situation under the accident run-out rates separately by 0.05% and 0.1% at the same lane number of the main road,each run-out time of accident vehicle by 15min under two conditions of installing and not installing the multi-function lane.The article analyzes the necessity of installing the multi-function lane by the comparison of the traffic capacity and the other vehicle delay of the main line if the installation and no installation of the multi-function lane when a vehicle emergently stops.
