• Abstract:
  Weather causes a variety of impacts on the transportation system. While severe winter storms, hurricanes, or fl ooding can result in major stoppages or evacuations and cost millions of dollars, the day-to-day weather events such as rain, fog, snow, and freezing rain can have a serious impact on the mobility and safety of users. The application of IntelliDriveTM technologies, Road Weather Information Systems (RWIS), and weather/traffi c data collection and forecasting technologies, presents new opportunities to improve the safety and mobility of the traveling public through improved knowledge and understanding of how individual drivers behave during adverse weather, and analyzing how their decisions collectively impact traffi c fl ow. This information can then be used to support weather-responsive traffi c management strategies such as real-time modifi cation of traffi c signal and ramp meter timings, automated deicing systems, and variable speed limits. Despite the documented impacts of adverse weather on transportation, understanding the linkages between inclement weather conditions and traffi c fl ow remain tenuous.
