The report reviews an experiment undertaken to examine the effectiveness of five sign treatments for controlling driver speeds in the vicinity of hazardous horizontal curves on rural two-lane highways. Signs examined ranged from the standard curve warning arrow to a regulatory speed zone sign in conjunction with a curve warning sign. Data collected during the experiment included both the following electronic and manual data: speeds of motorists as they approached and negotiated two horizontal curves, vehicle classification and registration information, and whether vehicles crossed over center and edge line markings.

Warrants and guidelines for warning and regulatory signs and markings in the Manual on Uniform Traffic Control Devices (MUTCD) are evaluated for functional, economical, and aesthetical applicability to low volume rural roads. The research involves classifying the types of low volume rural roads and identifying driver information needs on the various classifications. Supplemental guidelines to the MUTCD based on safety, costs, and aesthetics are developed and validated.
