HUMAN FACTORS REQUIREMENTS FOR REAL-TIME MOTORIST INFORMATION DISPLAYS. VOLUME 11. HUMAN FACTORS EVALUATION OF ROUTE DIVERSION AND GUIDANCE VARIABLES

The document summarizes the laboratory research findings in nine topic areas dealing with message design criteria associated with route diversion and guidance. Several of the studies were replicated in different regions of the United States. The research objectives dealt with issues of content, format, and associated understanding of messages to be displayed both on static signs and changeable message signs (CMS). Among the issues explored were advanced signing upstream of an advisory CMS for diversion; understanding of major point diversion sign coding; the content and format of the advisory CMS message for diversion and secondary verbal messages for route assurance; the meaning conveyed by names given to the diversion route; techniques for guidance to multiple destinations and major generators and for guidance when the driver has passed the correct turn; and, finally, regional differences in names for frontage roads and freeways going around or to one side of a city.
