EVALUATION OF REAL-TIME VISUAL INFORMATION DISPLAYS FOR URBAN FREEWAYS WITH DISCUSSION

A QUESTIONNAIRE AND SLIDE PRESENTATION, DESIGNED BY A MULTIDISCIPLINARY TEAM, WERE ADMINISTERED FOR THE PURPOSE OF DETERMINING DRIVER PREFERENCES FOR REAL-TIME VISUAL INFORMATION DISPLAYS FOR URBAN FREEWAYS. A TOTAL OF 505 EMPLOYEES OF 17 ORGANIZATIONS IN THE CITIES OF HOUSTON AND DALLAS PARTICIPATED IN THE SURVEY. EVALUATION OF THE RESPONSES PROVIDED DESIGN INPUTS FOR THE DEVELOPMENT OF A REAL-TIME FREEWAY INFORMATION SYSTEM. IT WAS FOUND THAT PARTICIPATING MOTORISTS PREFERRED REAL-TIME INFORMATION DISPLAYS THAT WERE SIMPLE IN NATURE OVER DESIGNS CONTAINING DIAGRAMS THAT ORIENT THEM TO THE FREEWAY ARTERIAL STREETS. THEY ALSO INDICATED A PREFERENCE FOR UNIQUE DESIGN FEATURES, SUCH AS THE USE OF COLOR, TO DISTINGUISH BETWEEN USUAL AND ABNORMAL TRAFFIC CONDITIONS. IN ADDITION, THE SURVEY INDICATED THAT THE MOTORISTS FAVORED A DESIGN THAT EXPLICITLY DISTINGUISHES REAL-TIME VISUAL DISPLAYS FROM OTHER TYPES OF FREEWAY SIGNING. EVALUATION OF SYMBOLS (CIRCLE, ARROW, OR BAR) THAT COULD BE USED AS PART OF A REAL-TIME VISUAL DISPLAY INDICATED NO PREFERENCE FOR ANY OF THESE SYMBOLS. /AUTHOR/
