Development and Evaluation of Vehicle Rear Lightining Systems

H. W. Case / S. F. Hulbert / O. E. Patterson / R. I. Emori / J. M. English

An analytical technique for developing vehicle rear lighting system requirements was formulated. The technique was utilized to generate preliminary performance requirements and to translate them into alternative design approaches. Two candidate rear lighting configurations were then designed and fabricated as scale models. A method of superimposing programmed images of candidate rear lighting configurations onto motion picture highway scenes in the Driving Simulation Laboratory was developed and evaluated. Preliminary evaluation of the two candidate configurations was conducted, utilizing the newly developed superimposition technique to present moving vehicle situations to drivers and compare their responses to a 'normal' taillight configuration. An instrumented vehicle system for field experimentation was designed, components acquired and/or fabricated, and assembly of the system conducted. A literature search was conducted, and a bibliography containing over five hundred entries was compiled. To facilitate utilization, the entries were also divided according to subject matter and according to author. A photometric investigation was also conducted. (Author)
