多目标优化问题在平面交叉口减排中的应用

Application of Multi-Objective Optimization Problem in Emission Reduction at Intersections

在道路的平面交叉口位置,多向机动车、非机动车车流和行人同时利用一个平面,容易造成通行能力的下降,严峻的交通状况使得车辆排放急剧增加,从而对大气环境造成恶劣影响,所以需要从多个层面对交叉口排放进行优化。本文通过介绍多目标优化问题的算法,归纳已经建立的同时兼顾交通流和机动车尾气排放情况的平面交叉口控制模型,了解交叉口效益与环境双优的发展进程以及多目标优化算法在实现双优中的应用,进而对未来的研究方向和技术创新提供建议。

At the intersection of the road,multi-directional motor vehicles,non-motor vehicles and pedestrians use the same plane at the same time,which is likely to cause a decline in traffic capacity.Severe traffic conditions cause a sharp increase in vehicle emissions,which has a bad impact on the atmospheric environment.So it is necessary to optimize the intersection emission from multiple levels.This paper introduces the algorithm of multi-objective optimization problem,summarizes the established level intersection control model that takes into account both traffic flow and motor vehicle exhaust emissions,understands the development process of the intersection benefit and environment,and the multi-objective optimization algorithm is achieving dual application of excellent quality,and then provides suggestions for future research directions and technological innovation.
