In order for a traffic micro-simulation model to be effective, it must be able to replicate both supply and demand characteristics, as well as their interaction. That is, the simulation model must be properly calibrated. The recent widespread deployment of ITS in North America has provided an opportunity to obtain significant amounts of traffic related data on a point, link, and trip basis. In addition, there has been a corresponding increase in the quality and quantity of micro-simulation models that can be used to model transportation systems. A methodology for calibrating traffic micro-simulation models so that the simulation results, such as travel time, represent the observed distributions obtained from the field will be presented. The focus of the talk will be on lessons learned from various calibration-related research projects over the past ten years. The seminar will conclude with a discussion of current and future research initiatives in this area.
