The report describes the design, performance, and operation of a driving simulator for use in vehicle rear lighting and related studies. The results of two simulator validation studies are also described. The purpose of the simulation was to represent a straight, two-lane road with a lead vehicle in the lane being driven. The test subject has accelerator and brake controls only, steering not being provided. Car-following tasks or overtaking without passing can be simulated, in day or night driving conditions. Approximations to rear vehicle acceleration and braking dynamics are used. Scaling and control of lamp intensity and color is achieved, with flexibility in varying rear lighting system display and operational characteristics. Lead car speed and signaling can be controlled manually or by magnetic tape records. The latter reproduces the speed-time history and signal actuations from a real vehicle under the highway and traffic conditions existing when the recordings were made. A digital computer interface provides system control, storage or rear lighting systems, and real time data acquisition and analysis.
