Assessment of Target Visibility in a Scale-Model Simulator Under Different Layouts of Conventional Fixed Lighting
Quantitative measures have been made of the visibility o sample target objects under each of five layout arrangements of fixed highway luminaires, with each of two pavement surfaces. The study was conducted in a model simulation of an eight-lane urban freeway, constructed at a scale of 1:15. Targets included a human figure, an unlighted vehicle, and a white line marker. Luminaires resembled the conventional Type III Medium Semi-Cutoff variety, and were placed at a 35-foot mounting height. Pavement surfaces resembled Portland Cement concrete and bituminous concrete. Visibility was assessed by a combination of psychophysical and physical measurement procedures in terms of the effective visibility level. (Modified author abstract)
