基于微观仿真的交叉口车辆能耗与排放研究

为了更加准确地模拟交叉口机动车能耗、排放情况,结合使用微观仿真模型VISSIM与微观能耗、排放模型PERE,构建能够模拟车辆瞬时运行状况与能耗、尾气排放关系的微观模拟平台。选取上海市西藏北路—海宁路交叉口进行实例仿真,通过设置交叉口锯齿形公交优先进口道及改变信号周期,来定量分析对交叉口车辆能耗和排放的影响。结果表明,设置公交专用进口道可使公交车辆总体排放明显下降,但是社会车辆的能耗和排放有所增加;对车均延误、停车次数、能耗与排放都合适的最佳信号周期范围是80～120s。

Investigating Vehicular Energy Consumption and Emissions at Intersections with Micro-Simulation Models

To accurately model vehicular energy consumption and emissions at intersection, this paper develops a micro-simulation platform based on VISSIM and PERE models to investigate the relationship between vehicular speed and energy consumption; vehicular speed and emissions. Taking the intersection of Xizang North Road and Haining Road in Shanghai as an example, the paper conducts a quantitative analysis on the impacts of the priority stop line for bus at intersection and signal cycle length on vehicular energy ...
