Paradoxes of Network Expansion with Simultaneous Departure Time and Route Choices
Some new dynamic phenomena of Braess's paradox are investigated considering simultaneous departure time and route choices in transportation networks. The traditional bottleneck models with deterministic queues are employed to describe user's departure time choice behavior, and the Wardropian UE principle is used to characterize route choice behavior. Novel dynamic paradigms of Braess's paradox have been found with both point queue and physical queue assumptions, and the mechanisms of such paradoxes are analyzed in details. And it is revealed that paradoxes are more likely to happen in networks with physical queues than point queues. Then we examine under what conditions the paradox may happen in some typical networks. Finally, appropriate approaches are proposed to resolve paradoxes, such as link closing, ramp metering, time-varying road pricing, lane partitioning, and adaptive traffic control etc.
