Objectives:

A study of the influence of vehicle headlamps and roadway lighting on the ability of drivers to see pedestrians along crosswalks in roundabout intersections

Methodology:

An outdoor field experiment was conducted to assess observers’ ability to detect and identify the walking direction of pedestrian targets in the field of view.

Key Findings:

  • The results suggest that vehicle headlamps have a significant role to play in pedestrian detection along roundabout intersections.

  • Systems such as HID headlamps, which produce greater amounts of peripheral illumination can result in shorter identification times for pedestrians.
