Statewide Mesoscopic Simulation for Wyoming.

摘要

This study developed a mesoscopic simulator which is capable of representing both city-level and statewide roadway networks. The key feature of such models are the integration of (i) a traffic flow model which is efficient enough to scale to large regions, while realistic enough to represent traffic dynamics, including queue growth and dissipation and intersection control; and (ii) a user behavior model in which drivers choose routes based on minimizing travel times. Integrating these models is nontrivial, because route choices depend on route travel times, but route travel times are determined from route choices through the traffic flow model. An iterative approach is used to seek a consistent solution to this problem, using the cell transmission model as the traffic flow model.
