TL;DR: This paper takes a first step towards formulating and solving a class of discrete time, nonlinear models that are extensions of those in Carey (1987), and its effects on traffic flow are analyzed using small traffic networks.
Abstract: Although several optimization models have been proposed for the dynamic traffic assignment problem, little computational experience is available. In this paper, we take a first step towards filling this gap by formulating and solving a class of discrete time, nonlinear models that are extensions of those in Carey (1987). An exit function is proposed, and its effects on traffic flow are analyzed using small traffic networks. The performance of three widely available optimizers in solving these models is described. Solution features of both nonlinear and piecewise linear versions of the model are presented and compared with simulation results generated using the Dynasmart simulator.
