Abstract

TRL carried out a number of off-road research trials to investigate the legibility and comprehension of traffic messages showing text and pictograms. This involved both trials at motorway driving speed (dynamic) to establish the comprehension of text messages and pictograms and stationary trials at fixed distances from the MS4 (static) to investigate text message and pictogram legibility. Discusses the results of these trials and offers recommendations for adoption into future practice.
