Abstract

The purpose of the study was to determine the cost-effectiveness of widening lanes and shoulders on rural, two lane roads. Information concerning geometrics, accidents, and traffic volumes was obtained for over 15 000 km of roads. Reductions in accident rates occurred as lane and shoulder widths increased.
