EVALUATION OF TECHNIQUES TO IMPROVE THE LEGIBILITY OF BILINGUAL VARIABLE MESSAGE SIGNS

This study compared the legibility of several Variable Message Signs (VMS) configurations in a controlled laboratory setting using a tachistoscope to record reading response times. The signs were viewed by monolingual (English) and bilingual (Welsh and English) participants under ideal viewing conditions. Results from the study suggest that embedding text in a bilingual road sign increases reading time, compared to a situation where the text was presented separately in a monolingual sign. This increased reading time represents an increase in the search time required to locate the relevant information and could have implications for driver distraction. A number of demarcation techniques were found to aid drivers in their visual search, with the proviso that, if used, these techniques should be implemented at a national level so as to minimize driver confusion. Further work should concentrate on systematically incorporating the task of sign reading into the driving task in order to evaluate various sign configurations.
