Assessment and Improvement of Motorist Understanding of Traffic Control Devices

摘要

A three-year study of motorist understanding of traffic control devices iscurrently under 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 would be evaluated for possible improvement through revision to standards or public education. The interim report outlines research activity directed to literature assimilation, selection methodology for traffic control devices of study, development of survey instrument and administration procedures, pilot survey results, and continuation of study. Survey data collection, analysis and evaluation for comprehension improvement will continue in the second and third years of effort. Results and recommendations will be part of the final report, published at the conclusion of the study.
