Texas freeways experience considerable traffic congestion—sometimes from high traffic volumes and others from minor or major traffic incidents. Whether from minor (e.g., crashes, stalls, and road debris) or major (e.g., vehicle rollovers, chemical spills, flooding, and hurricane evacuations) incidents, freeway systems can come to a complete standstill, which results in significant economic impacts for Texas drivers and businesses. Quick response and clearance of traffic incidents through traffic incident management (TIM) practices is a proven method of restoring roadway capacity and increasing mobility on urban freeways. Transportation agencies and emergency responders are continually seeking new technologies and systems (especially for major incidents) that can improve response times, monitoring, and clearance. One such system/technology under consideration is unmanned aircraft systems (UAS). Commonly referred to as drones in military applications, public and civil UAS could prove to be a flexible and useful tool for transportation agencies and emergency responders. |
