Abstract:A three-year study of motorist understanding of traffic control devices is currently in progress. The objective of the study is to conduct a detailed assessment of motorist comprehension of signs, signals, and markings utilizing a statistically valid survey of Texas motorists. Those traffic control devices determined to be less than adequately understood will be evaluated for possible improvement through revision to standards or public education. This interim report presents survey results and research directed to evaluation of motorist comprehension of selected traffic control devices. In-depth study findings and recommendations for improvement in understanding and response by motorists to specific traffic control devices will be addressed in the final report, to be published at the conclusion of the study.
