With the progress of modern society and the vigorous development of the automobile industry, traffic congestion occur continuously in urban roads. In addition, with the acceleration of the urbanization process in our country, the number of urban population and the number of cars are increasing constantly, which leads to the increasingly serious traffic congestion, and a series of traffic problems and environmental problems. The project selected Hanjiang Road in Yangzhou as the research object, and compared the current city fast track intersection vehicle exhaust emissions with green wave traffic signal control vehicle exhaust emissions under uniform traffic to highlight its energy saving effect, the benefit and improvement of the air environment. It also provided a theoretical reference to promote green traffic signal control for the construction of ecological society.%随着现代社会的进步以及汽车工业的蓬勃发展,城市道路不断出现交通拥挤、阻塞现象.加之我国城市化进程速度的日益加快,城市人口数量和汽车保有量不断增加,致使道路拥堵现象日益严重,同时引发一系列交通问题和环境问题.本项目选取扬州市邗江中路为研究对象,将当前城市快速通道的交叉口汽车尾气排放与绿波交通信号控制下匀速行驶的汽车尾气排放进行对比,突出其节能减排的效益和改善空气环境的作用,为建设生态社会,推广绿波交通信号控制提供理论参考.
