Field-test to determine the optimal traffic sign illumination based on glare-free high beam.

Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
At the Technische Universität Darmstadt a study is performed to find the optimal traffic sign illumination that does not result in glare (through an outshining of the traffic sign) and maximizes the identification distance. This is done by a dynamic field study, in which a vehicle with glare-free high beam passes with constant speed, traffic signs located to the left and right side but also in front of the driver, simulating a sign in a bend. After passing with low beam (lower limit) and high beam (upper limit), high beam is dimmed stepwise to simulate different levels of masking out traffic signs. To find the optimal masking level, identification tests are performed for each high beam intensity. By combining the identifi-cation distances with the identification luminance, the glare rating and brightness rating, the optimal traffic sign illumination can be found. Furthermore, illuminance is measured during each passing process, both at the traffic sign and at driver’s eye position. To receive a correlation between measured illuminance and distance, a GPS system is placed on both vehicle and traffic sign.
