Incident detection on urban freeways
WebReal-time incident detection on freeways plays an important part in any modern traffic management operation by maximizing road system performance. The US Department of Transportation (US-DOT) estimates that over half of all congestion events are caused by highway incidents rather than by rush-hour traffic in big cities. WebFreeway management systems are planned for other major metropolitan areas in Texas such as Amarillo and Corpus Christi. An important goal of these systems is the rapid …
