Abstract: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.
These features have been implemented in a software program, for which source code and tutorials have been
provided as appendices to this report. Additional modules are provided for generating graphical views of networks,
performing warrant analysis based on MUTCD procedures (either to assist with network creation, or as a postprocessing
step), and a spreadsheet interface to the program itself. Ready-to-use networks have been provided
representing the city of Casper and the state of Wyoming.
