Samenvatting
Typical night vehicle meeting engagements on unlighted two-three- and four-lane highways were simulated. Vision tasks for subject drivers were provided utilizing common highway visual objects are targets. Various vehicle headlight systems including standard low and high beam, high intensity and polarized lamps were studied under varied conditions of vehicle speed and separation distances between opposing single and multiple vehicles with respect to the vision targets with drivers having varied glare adaption response. Measurements were made of detection distance capabilities of the observers and their steering response to targets and oncoming glare vehicles.
