A Microscopic Traffic Flow Model Characterization for Weather Conditions

Road surfaces are affected by rain, snow, and ice, which influence traffic flow. In this paper, a microscopic flow model based on weather conditions is proposed. This characterizes the severity index. The Intelligent Driver (ID) behavior constant acceleration exponent resulting in similar regardless of conditions, unrealistic. ID proposed models evaluated over circular road length 800 m. results obtained indicate that velocity density better than model. Further, variations with smaller during adverse weather, as expected. It also shown stable model, even weather.
