Abstract

This investigation evaluated the effectiveness of specific sign installations in reducing reported accidents. The before and after study method was used to evaluate 34 sign installations. Accident predictive methods were investigated for curve warning, advisory speed, special combination advisory speed, and 4-way stop sign installations. Since the costs of the signs are very small, this kind of safety improvement can be made at bargain rates. (Author/publisher)
