Dynameq Application to Evaluating the Impact of Freeway Reconstruction

This paper presents the first application of Dynameq to a freeway reconstruction impact study in the United States. Dynameq is a simulation-based equilibrium dynamic traffic assignment modeling software. The equilibrium solution property and the close to microscopic simulation traffic fidelity level make it an excellent tool in the traffic impact study. I-15 reconstruction project in Ontario, CA, involves mainline lane closure, ramp closure and freeway-to-freeway connector closure. The application model simulated the temporal effects of the closures on both freeways and arterials. The model development, calibration and reasonableness checking as well as the results from one of the construction scenarios, including the diversion routes and delays due to the construction, are presented in the paper.
