Human Factors Design of Dynamic Visual and Auditory Displays for Metropolitan Traffic Management. Volume 1. Summary Report

摘要

This report summarizes the findings and design implications of a series of research studies with respect to parameters of dynamic visual displays (Changeable Message Signs) and auditory displays (Highway Advisory Radio). Laboratory, proving ground and field studies were conducted. Dynamic visual display factors investigated have been classified into five areas: message factors, character factors, accentuation factors, dynamic factors, and visibility factors. In-situ controlled field studies were conducted to validate findings from previous HAR laboratory studies. Specific areas investigated were: language style, information load, redundancy, description of alternate routes, and advance road sign for radio tuning.
