Traffic signs, markings and signals recommeded for a manual on uniform traffic control devices were evaluated both in the laboratory and on the road to measure the recognizability of both standard and experimental signs. Visual presentation was chosen as the independent variable. An important conclusion is that road testing and laboratory testing can complement one another. A questionnaire was designed to provide information about population stereotypes as to the meaning of the traffic control device as a symbol, the implication of this meaning for action, and, the preference for one control device over another. The document is volume one of a two volume report.
