Bangladesh, a South Asian Country with a large population of about 130 million people in a small land area of about 144000 sq. km. Dhaka, the capital city. is the centre of all administrative, economic and cultural activities. The city has a population of about 10 million people in an area of about 2000 sq.kms. The total road length of the city is about 3000 kms.
The city is divided into two parts i.e. Old Dhaka and New Dhaka. In the Old part roads are narrower and most of them are not accessible to buses and some of them are not even accessible to motorized vehicles. In the New part the roads are comparatively wider and the movement of traffic is better. There are some negative impacts of City's transportation system on human health and environment due to pollution and road accidents. In this paper focus will be on air pollution due to auto-mobile emission in Dhaka City and the measures taken for the control and management of automotive air pollution.
