Driver behavior was analyzed using video data, and local residents/frequent users were surveyed about their perceptions and experiences.

ContextRural intersection safety and traffic engineering.

Variables

IVPresence and activation of the active LED warning system.

DVDriver behavior (e.g., speed, reaction time, gap acceptance), perceived safety, awareness.

CVIntersection geometry, existing traffic control devices, time of day, weather conditions.

Strengths & Limitations

Strengths
