特定城市汽车尾气PM2．5控制办法研究

摘要

特定城市具有特定的地理环境和气候条件，不同城市的道路交通设计和交通管理水平不尽相同，因此不同城市的汽车尾气中PM2．5颗粒物扩散的速度和叠加效应各具特点。文中创新性地从汽车尾气排放PM2．5与气候及车辆行驶速度的关联性角度分析，找出特定城市汽车尾气PM2．5的控制办法，为特定城市找到一条适合自己的汽车尾气PM2．5治理办法提供思路。在解决思路中，文中创新性地提出“车联网”的概念，使城市交通做到双向主动管理。%Specific city is with specific geographical and climatic conditions,and the roads design and traffic management levels vary in different cities too,so the spread velocity and the superimposed effect of PM2.5 particulate matter of vehicle exhaust in different cities is characteristic.This article analyzes innovatively the relevance between vehicles PM2.5 and vehicle speed,as well as climate,find control methods for PM2.5 of vehicle exhaust for specific city,provide idea for suitable management methods for PM2.5 for specific city.In solving ideas,this paper propose innovative concept of“networked car”,it leads bidirectional and active management for urban transport.
