Research on Bi-Level Dynamic Traffic Assignment

In this dissertation, the model of bi-level optimization of dynamic traffic assignment has been presented. This model makes dynamic system optimum under the precondition of ensuring dynamic user optimum. In other words, it makes the travel fee in the system as cheap as possible, while reducing every user cost. As we set up the theoretic model of dynamic traffic assignment, we consider the optimization of the traveler's route as the basic element. We consider not only the travel impedance of the vehicle but also the delay in the traffic queue caused by signal control in the intersection. After setting up the model of the bi-level dynamic traffic assignment, the authors give the algorithm.
