Title:

Identifying and Assessing Key Weather-Related Parameters and their Impacts on Traffic Operations using Simulation (Conference Paper)

Abstract:

This paper introduces a study conducted at Traffic Research Laboratory to identify how weather events impact traffic operations, assess the sensitivity of weather-related traffic parameters in the CORridor SIMulation (CORSIM) traffic microsimulation model, and develop guidelines for using the CORSIM model to account for the impacts of adverse weather conditions on traffic operations. A high-level conclusion from this project is that CORSIM can adequately be used to model the impacts 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 in-line with that expected from adverse weather.
