SimTraffic, a companion tool for Synchro, is a microscopic and Final/Approved Schematics and Design-stage tool used to evaluate intersections and networks. SimTraffic inputs are similar to Preliminary Schematic-stage tools, with the addition of driver behavior parameters (deceleration rates, reaction time, gap acceptance factor, etc.). Driver behavior parameters are modified for each of 10 driver types. As vehicles are added to the simulation, they are randomly assigned a driver type. SimTraffic outputs include traffic and environmental MOEs. SimTraffic simulations can be exported as video files. Typical applications of SimTraffic include analyzing signalized and unsignalized intersections.
