Abstract:

ABSTRACT

This study explores how "No Turn on Red" (NTOR) signs impact driver compliance and behavior at signalized intersections using a driving simulator. Data from 67 participants, navigating three scenarios (No sign, Static sign, and Dynamic sign), were analyzed to assess driver performance. The primary aim was to understand driver behavior concerning various NTOR signs, evaluating their speed profiles when approaching and turning at signalized intersections. Statistical and compliance analyses were conducted to assess driver performance. Results indicated that male drivers exhibited lower speeds in the presence of Dynamic signs, suggesting heightened attention and compliance. Compliance analysis revealed a higher adherence rate in the Dynamic sign scenario, emphasizing the effectiveness of its clear and easily understandable message in influencing driver behavior. These findings have implications for road safety, NTOR sign design, and educational strategies, offering valuable insights for future research and decision-making in these domains.

Learning Objectives:

Attendees can expect to learn the following from this session:

Identify the impact of "No Turn on Red" (NTOR) signs on driver compliance and behavior at signalized intersections
Analyze driver performance based on speed profiles when approaching and turning at signalized intersections in the presence of different NTOR signs
Evaluate the effectiveness of Dynamic NTOR signs in influencing driver compliance at signalized intersections
