Readability Impact of Symbols Displayed on Variable Message Sign

It is challenging for drivers to interpret the symbols currently displayed on variable message signs (VMS) used on Japan’s intercity expressways. Most people have expressed the need for symbols that are easy to see and understand. Thus, this study proposes symbols and examines their use on roads and in tests on a driving simulator. The effect of the legibility of complex symbols displayed on VMS at expressway junctions is also discussed.
