Video-based Conflict Analysis

Video-based conflict analysis is emerging as a promising approach for proactive traffic safety management. Unlike traditional crash data, which requires multiple years to accumulate, video-based measures such as Post-Encroachment Time (PET) and Time-to-Collision (TTC) can reveal risks in near real-time, enabling the North Carolina Department of Transportation (NCDOT) to act more quickly and effectively. Several state agencies have piloted such methods, but independent validation remains limited, and no standardized specifications or vendor prequalification procedures currently exist. This project will close these gaps by developing validated datasets, testing tools and methods, and producing practical guidance for NCDOT. A multi-stage methodology is proposed.
