The movement of residential locations to suburban areas to obtain cheaper land results in increasing mobility and infrastructure problems. One of the important infrastructures is transportation, which determines the level of accessibility of people and commodities from one place to another. Therefore, Transportation Demand Management (TDM) measures are important in providing an optimal transit route to increase accessibility of public transportations. In the past, several researchers have developed various TDM programs, including public transport improvement as a strategy to encourage a more transit-oriented society. This study attempts to create a methodology of identifying bus links between urban centers and newly developed urban expansion areas using Geographical Information Systems by considering reduction of route overlapping. A TAZ-based analysis is undertaken to identify the demand responsive bus routes, which maximize population coverage, minimize travel time, and reduce duplicating routes.
