Description of Paper:
Traffic simulation models should reflect a wide variety of operating and environmental conditions in order to be useful in estimation and prediction of real world traffic behavior. One area that traffic simulations have to accurately model is the effect that weather has on driver behavior and traffic flow characteristics. Recently, the Northwestern University and the University of Virginia have addressed this deficiency by investigating observed impacts of weather on both the supply and demand of traffic networks. This paper has two research purposes: to present the methodology for incorporating weather impacts into the DYNASMART-P traffic estimation and prediction tool and to assess the relative accuracy and fidelity of the developed weather module.
