摘要

This research paper presents an overview of controlling methods of engine emissions related to automotive fleet and road traffic characteristics. As urban populations expand and city roads become increasingly congested, city planners need comprehensive urban development and transport strategies to address deep-seated social and demographic change. Effective policies must meet multiple objectives:rn? Establishing a balance between different modes of transport: public transport, cars, motorcycles, bicycles, and pedestrians;rn? Providing security, safety and optimum service for transport system users;rn? Maintaining the urban mobility that entails economic development;rn? Reducing urban pollution caused by motor vehicles by controlling emissions.rnNowadays, urban pollution exposure from road transport has become a great concern in major cities throughout the world, these are the reasons for which the most used active and passive methods for controlling the motor vehicle emissions are presented.
