【课程简介】

Specifying choice sets is a fundamental challenge in route choice modeling: routes must be identified from network links, their number grows exponentially with network size, and travelers may choose non-shortest alternatives. Conventional random utility models with unbounded error distributions assign positive probabilities to all routes in the choice set, regardless of their attractiveness. Congestion further complicates stochastic traffic assignment through interactions between route choices and flow-dependent travel times. This seminar presents a truncated choice model (TCM) for route choice and stochastic traffic assignment. The TCM assigns zero probability to routes whose travel costs exceed a threshold representing travelers’ maximum acceptable cost. By endogenizing this threshold, the truncation conditions can be equivalently formulated as a convex mathematical program, facilitating model property analysis and algorithm development. Extensions of the TCM and recent developments will also be briefly discussed.
