Abstract

This paper investigates Braess-like paradox phenomenon in a transit network using activity-based approach. A time-dependent activity and travel choice equilibrium in terms of trip chain, departure time, route, and activity timing and duration over the time of day is formulated as an equivalent variational inequality problem to model the users' daily choices. This paper shows that when the supply side or demand side changes, the Braess-like paradox phenomenons would be different between activity-based model and trip-based model. The reason is that the activity-based model generates origin-destination pair demand according to activity trip chain flow, but the trip-based model doesn't. Numerical example is used to highlight the importance and advantages of the activity-based approach for modeling the Braess-like paradox problem in transit network. And the effects of demand side and supply side on the paradox occurrence are also presented in this paper.
