Summary: Public transportation is benefiting from the open-environment information system. Transit schedule information, made available by Google Developers General Transit Feed Specification (GTF), helps passengers choose their preferred transit routes more reasonably. For transportation planners a range of questions emerge including how the behavior of passengers looks and how we model this behavior with transit schedule information, We may also ask: What is the transportation assignment? How do we assign the passengers on this public transportation system? How do passengers choose their routes to arrive at destinations? What if the transit vehicle is congested by passengers? How do we integrate this assignment model with other transportation models such as activity-based model (ABM) and dynamic traffic assignment (DTA) model?

 

This seminar will address these questions using a well-known traffic assignment foundation, Wardrop’s user equilibrium (UE) and some behavioral assumptions. To define route choice behavior of passengers, we will explore important path models on a transit schedule network considering deterministic and stochastic passenger behaviors. With this transit assignment model, we can think about possible integration of other transportation models such as DTA model and ABM in terms of providing a better transportation planning model.
