ABSTRACT
Urban travel in Asian cities is predominantly by walking, cycling and public transport. The motorized and non-motorized paratransit services play an important role in providing affordable mobility to a large section of the citizens and form a large proportion of public transport trips. The formal public transport system has been replaced by an informal system where safety concerns have been compromised. Poor families, who are also transport-poor, are then denied accessibility to economic opportunities and have the burden of reduced mobility imposed upon them. If the informal sector is considered an integral sector of the urban economy then the improvement in transportation involves changing the design criteria for urban arterials. Delhi is showing declining trends in three-wheeler numbers because of restrictions on fuel and the age of public transport vehicles. The public transport fleet in Delhi has been converted to run on compressed natural gas.
