TESTING MOTORIST UNDERSTANDING OF TRAFFIC CONTROL DEVICES

In an effort to improve the traffic control device (TCD) communication link between the road operator and the road user, the Transportation Research Board Committee on Traffic Control Devices sponsored Conference Session 43 at the 1986 Annual Meeting on "Testing Motorist Understanding of Traffic Control Devices". The Conference purpose was to present an overview of problems which motorists have in understanding traffic control devices; to examine various methods for evaluating traffic control device understanding, including discussions of past and potential future techniques; and to obtain audience input on evaluating the feasibility of developing a standardized testing procedure for motorist understanding of TCD's. The ultimate goal was to develop adequate techniques for measuring TCD understanding and to establish threshold values as a prerequisite to the adoption or revision of standards for uniform TCD's. The Session was attended by approximately 85 professionals representing human factors, engineering and enforcement disciplines in government, industry and academia. This Circular contains edited presentations from the Conference Session and a Research Problem Statement which addresses the development of a standardized motorist testing procedure for use in evaluating TCD effectiveness.
