Summary
This report presents findings from a project aimed at understanding glare from vehicle lighting on UK roads. The project involved two primary activities: on-road data collection and a survey of UK drivers. The on-road data collection utilized an instrumented vehicle equipped with a luminance camera to measure glare and luminance levels during nighttime driving. Observers recorded instances of glare that interfered with their driving experience. The survey, conducted with a nationally representative sample of 1,850 drivers, gathered self-reported experiences regarding glare from vehicle headlamps. The findings indicate that many drivers perceive glare as a significant issue, particularly from bright headlamps, with over half reporting they have reduced or stopped driving at night due to glare concerns. The report also discusses the influence of vehicle types, road geometry, and environmental factors on glare experiences, suggesting that regulatory improvements and further research are needed to address this issue effectively.
