MOTORISTS' COMPREHENSION OF REGULATORY, WARNING, AND SYMBOL SIGNS. FINAL REPORT. VOLUME II: TECHNICAL REPORT

The purpose of this project was to identify, from existing research on warning, regulatory, and symbol signs, where deficiencies in motorists' understanding may pose safety or operational problems and to define acceptable levels of motorists' comprehension. The study developed alternative designs to remedy the identified deficiencies. These proposed alternatives were laboratory tested, and final sign designs were evaluated in a simulated highway environment. The results of the simulator evaluation were verified in closed field tests. See also Volume I: Executive Summary - FHWA/RD-86/111 and Volume III: Appendices - FHWA/RD-86/113
