Abstract:

Transport affects the local and global environment in many ways and for a number of pollutants the road transport sector is one of the most significant contributors to environment externalities. The transportation activities particularly related to motor vehicle have been closely identified with increasing air pollution levels in various urban centres of the world. Urban development is primarily linked with high vehicular density in urban areas which ultimately impacts air pollution. As most of the motor vehicles are found in urban cities and the trends is towards increasing urbanization specially in developing countries like India, it is expected that the vehicular air pollution related problems will further increase in future in these urban cities.
