This report reviews the inconsistency between various state laws and the Uniform Vehicle Code regarding lighting systems for special vehicles and school buses. Accident data are cited that may have pertinent implications to the problem of lighting systems design for these vehicles. Driver behavior problems that may be associated with the ambiguity of current signal messages are dicussed. Subsequently, an analysis of the signal messages that are necessary to conduct particular vehicular missions is presented. A review of lighting devices available disclosed that there is a diverse array of lighting devices available. Psychophysical visual and applied research was reviewed for information on the advantages and disadvantages of various coding parameters. An analysis of color, intensity, and flash rate summarized the information available that is applicable to special vehicle signaling systems. From this information was developed a set of recommended signals to transmit the messages deemed necessary for the efficient and safe conduct of various vehicular missions. These recommendations took into account current legal, stereotype, and changeover constraints. School bus signaling procedures were also reviewed and specific recommendations are made for new signals, usage procedures, legal language, and research.
