    • Abstract:
      The purpose of this study was to develop and test word and symbol traffic control and hazard warning messages for use on portable changeable message signs (PCMSs). The literature was reviewed, State highway engineers were interviewed, PCMS manufacturers were surveyed, and motorists were questioned to develop an extensive list of candidate PCMS messages for subsequent evaluation during the laboratory and field testing. More than 800 messages were identified for 30 situations. The laboratory studies were conducted to identify those key words or phrases that the motorist felt were most effective. Field tests, both daytime and nighttime, were conducted for candidate messages that lacked a clear winner during the laboratory studies. Also six symbol messages were shown during the field tests to evaluate motorist comprehension of these messages. This summary report presents some of the research results. The full report, which has the same title as this summary report, is FHWA-RD-95-171 (TRIS 00720253).
