Beating the congestion in Dhaka
Nearly 17 million people live in Dhaka, the capital of Bangladesh. The majority of people live in the city centre and traffic congestion is a problem. However, there are many auto rickshaws (a small, three-wheeled vehicle, driven by a motorcycle engine) competing in the city centre to take passengers to their destinations. Fares tend to be cheaper in the city centre than they are outside the city centre and are usually agreed between passengers and drivers.
Dhaka has a large number of auto rickshaws competing for fares.
