Stochastic Equilibrium Assignment with Variable Demand: Theoretical and Implementation Issues

This paper will discuss how it has recently been pointed out that transport models should reflect all significant traveler reactions. In particular, trip generation, trip distribution, modal split and route choice should be modeled in a consistent process based on the equilibrium between transport supply and travel demand. Such an issue is all the more significant when congestion of the transport network is not negligible and when several alternative modes/routes are available. In this paper a general fixed-point modeling framework is presented that allows dealing with stochastic user equilibrium assignment with variable demand. The focus of this paper is on model solution following the so-called “internal” approach as well as the “external” one. Algorithms are proposed and their effectiveness are investigated in the paper.
