This is a report of an investigation of the effects of different rear lighting and signaling configurations on measures felt to be important in determining traffic flow characteristics. Three studies are reported: two conducted during the night and one during the day. The two nighttime studies employed three different rear lighting configurations. The first study was carried out with a two-car platoon and the second with a three-car platoon. The only significant differences were in reaction time measures. A configuration having separation of function and color coding produced shorter reaction times than the other systems tested. The daytime study was conducted primarily to investigate the value of high-mounted signal lamps. It was found that the high-mounted signal lamps significantly shortened reaction times in multiple car-following situations.
