Abstract:In February 2007, a winter storm comprised of rain, ice and snow caused multiple accidents on Pennsylvania’s interstate highway. Twenty five percent of interstate routes were closed for extended periods of time. Many motorists were stranded along interstate corridors. Local and state resources were diverted from their primary duties during the storm to remove motorists from traffic queues and to manage detour routes. This combination of incidents prompted the Pennsylvania Department of Transportation (PennDOT) to deploy a management system for temporary speed restrictions and vehicle restrictions along the interstate. The goal of this effort is to reduce accidents stemming from inclement weather on the state’s limited access highways.
