Abstract

It is well recognized that inclement weather conditions can severely affect mobility and safety. According to the Federal Highway Administration (FHWA), adverse weather is the second largest cause of nonrecurrent congestion. Thus, rain can increase travel time delay by 12% to 20%. Nevertheless, there is no real implementation of weather-responsive traffic management tools except for winter operations and maintenance systems. Indeed, road managers and operators continue to apply traffic management strategies that are still not sensitive to weather conditions. At the same time, advances in sensor technologies enabling real time monitoring of roadway and environmental conditions offer ways to create better decision-support tools for road managers. Although much is known about weather effects on traffic, little has been achieved to date. This work aims at contributing to design and developing weather-responsive traffic management strategies for urban and interurban motorways.
