摘　　要：设置综合待行区的信号交叉口评价指标多以体现交通运行状态为主,难以体现交通环保的影响。本文通过实地调查,根据交叉口综合待行区设置条件和设置原理,在东西主干道上设置了综合待行区,运用VISSIM仿真软件输出相关数据值,选取了排队长度、平均信号控制延误、平均停车次数、一氧化碳、氮氧化物、总悬浮颗粒物作为评价指标,基于专家评分和优序图法对实际交叉口综合待行区设置前后进行综合评价,结果显示,设置综合待行区使得交叉口运行效率有所改善,但考虑环保后的评价结果有所下降。交叉口综合待行区的设置能够为分析解决交叉口交通问题提供借鉴。The evaluation indexes of signalized intersections with comprehensive waiting areas mainly reflect the traffic operation status,which is difficult to reflect the impact of traffic environmental protection.In this paper,according to the setting conditions and principles of comprehensive waiting areas at intersections,comprehensive waiting areas are set up on east and west main roads.VISSIM simulation software is used to output relevant data values,and queue length,average signal control delay,average parking times,carbon monoxide,nitrogen oxides and total suspended particulate matter are selected as evaluation indicators.Based on expert scoring and priority diagram method,comprehensive evaluation is made before and after setting up comprehensive waiting areas at actual intersections.The results show that setting up comprehensive waiting areas can improve the operation efficiency of intersections.The setting of comprehensive waiting area at intersections can provide reference for analyzing and solving traffic problems at intersections.
