摘要
车流波现象是城市交通流中一种不稳定状态。当城市快速路出现车流波现象时,车流运行的平稳性会明显降低,同时燃油消耗量和尾气排放量却随之上升。因此,对车流波状态下尾气排放进行研究是十分必要的,对于整个城市大气环境的改善意义重大,也更加有利于和谐、可持续交通的发展。
Shockwave is an unstable condition of urban traffic flow. When shockwave happen in urban expressway, the stability of traffic flow will decrease, and the oil exhaust and gas emission will increase. Therefore, study of gas emission under shockwave condition is very essential, which is of great significance for the improvement of the whole city atmosphere environment, and is helpful for harmous and sustainable traffic development.
