This report describes the findings of a study evaluating a variety of proposed signs for the Manual on Uniform Traffic Control Devices (MUTCD). The sign investigated included: a series of light rail signs, Lane Ends, Cellular Phone Emergency Number, Rural Mail Delivery Route, Share the Road with Bikes, Electric Vehicle Charging Stations, and Scenic Byways Designation. The study included determination of comprehension and recognition distance for two versions of the signs under investigation, using 24 older (65+) and 24 middle-aged (21-45) licensed drivers. Recommendations are made for which signs should be considered for the MUTCD and for further research needed. |
