The purpose of this project is the design and testing of improved marking and lighting systems for large commercial vehicles. Results of Task I are presented covering: (1) U.S. Truck population characteristics; (2) Analysis of vehicle-into-truck accidents; (3) Analysis of driver capabilities; (4) Analysis of FMVSS 108; (5) Development of functional requirements for marking and signalling systems; and (6) Analysis of retroreflective materials. An extensive bibliography is included. Fleet operational experience with retroflective markings and the results of a pilot study of car and truck rear-light intensities are also reported. It is concluded that improved marking and signalling have a high probability of reducing vehicle-into-truck accidents.
