STOCHASTIC NETWORK EQUILIBRIUM MODELS CONSIDERING BOTH STOCHASTIC TRAVEL DEMAND AND ROUTE CHOICE

Abstract

Under the ordinary circumstance without any accidents and disasters, the main causes of transportation network’s uncertainty are variations of travel demand and route choice behavior. We assume that travel demand and route choice are stochastic, and develop stochastic network equilibrium models. In the models, network flows and travel times are also stochastic due to stochastic travel demand and route choice. The models are promising for assessing uncertainty or travel time reliability of transportation network and analyzing its stochastic properties theoretically.
