Confronting the Challenges in This Information Age: Towards a New Transit Modeling Approach

Abstract

Information is affecting our life in significant ways. Transit planners have a dream that one day they can fully utilise all available information as the model input, and the planning tool is also able to provide valuable information for policy making.

All is dream in the past in view of the lack of information (such as the detailed time-dependent origin-destination (O-D) demand information), as well as the limitation of computation power. As such, the conventional transit models often simplify the real situation or ignore some of the system/passenger behavior. With the advent of the information age, the introdu...
