Human Factors Design of Dynamic Visual and Auditory Displays for Metropolitan Traffic Management. Volume 3: Highway Advisory Radio

摘要

This study was concerned with the development of recommendations for the design of dynamic visual displays (Changeable Message Signs) and auditory displays (Highway Advisory Radio) for use in managing traffic in metropolitan areas. This volume presents the results and recommendations of in-situ and field studies aimed at validating findings from previous HAR laboratory studies. Specific areas investigated were as follows: language style, information load (message length and number of components), redundancy, description of alternate routes, and advance road sign for radio tuning. In-situ studies were conducted in San Antonio, Texas using 6-, 8-, and 10-unit diversion routes. Field studies were conducted in New Braunfels, Texas during the annual Wurstfest Festival. The event attracts people from several cities in Texas. An HAR system was used to divert Wurstfest traffic to a less congested route.
