Book excerpt: "The next generation motor vehicle emission rate model used in the US, the United States Environmental Protection Agency's Motor Vehicle Emmission Simulator (MOVES), requires second-by-second vehicle data in order to fully utilize model capabilities. However, field data collection of this type of data is resource intensive and frequently not realistic for local agencies. Some microsimulation models have the capability of outputting instantaneous speed and acceleration, which can be used in MOVES. With these capabilities, microsimulation offers a valuable tool to conduct analysis requiring a large number of data. ... Two case studies were used to assess the utility of the microsimulation model, Vissim, in developing output that can be used as input to MOVES. In one scenario, drivers were selected to drive an instrumented test vehicle along a test corridor. In another scenario, five drivers drove through a roundabout in the University of Iowa national Advanced Driving Simulator (NADS). Models for each scenario were also developed in Vissim. Model output was compared to field collected speed/acceleration profile data to assess the accuracy of microsimulation models in providing realistic estimates of vehicle activity as input to MOVES. Results were summarized to demonstrate the applicability of linking microsimulated vehicle activity data with emissions models to better estimate the emission impacts of different transportation strategies" (page vii).
