A Network Signal Timing Design Bilevel Optimization Model with Traveler Trip-Chain Route Choice Behavior Consideration

Abstract

This study proposed a bilevel optimization model for the network signal timing design problem by considering the link flows reflected by the trip-chain route choice behaviors of road users. The bilevel programming model is formulated based on the interactions between signal timing control and trip-chain behavior, and a solution algorithm by combining variational inequality sensitivity analysis, the generalized inverse matrix method, and a gradient projection approach revised for trip-chain user equilibrium is developed for the transportation design problem. The performance of the developed model framework was verified through numerical analysis under different test scenarios.
