Rapid economic development and urbanisation cause serious traffic problems. To combat the traffic issue, many countries have begun to implement Transit Oriented Development (TOD). TOD can not only promote the development of public transport and alleviate traffic congestion but can also effectively curb urban sprawl and urban land problems, which have an impact on urban social development. This paper will use the city of Chengdu as an example to study the social impact of TOD on urban development.
