Abstract:

The objectives of this study were to identify how weather events affect traffic operations, to assess the sensitivity of weather-related traffic parameters in the CORridor SIMulation (CORSIM) traffic microsimulation model, and to develop guidelines for using the CORSIM model to account for the affects of adverse weather conditions on traffic operations. ; This report summarizes the methodologies, findings, and conclusions for each of these study objectives. A high-level conclusion from this project is that CORSIM can be used adequately to model the affects of weather events on traffic operations. This conclusion is based on the fact that a majority of the generic weather-related parameters identified are currently available in CORSIM, and that the key weather-related parameters are adequately sensitive in producing model outputs inline with that expected from adverse weather.
