Abstract

This paper describes how accident data and travel data can be combined to provide a basis for setting priorities and evaluating safety effects of new vehicle-based roadway illumination specifications.

Methods for making distinctions between daylight and darkness are applied to both accident tabulations and vehicle miles of travel tabulations. Exposure-based accident rates are calculated for several types of accidents and roadways.

Measures for improvements in safety are discussed in terms of reductions in nighttime exposure-based rates as related to improvements in visibility of signs, road markings and general aspects of the roadway environment.
