Title: Design and Evaluation of Signs and Pavement MarkingsUsing Driving Simulators
Abstract: Drivers rely on traffic control devices for guidance, regulatory, and warning information while traveling. These devices, primarily signs and pavement markings, must be easily seen and comprehended in order to be most effective. Driving simulators offer a safe and low-cost environment in which to test the effectiveness of traffic control devices in a variety of roadway conditions. They provide repeatability for experimental control and flexibility to quickly evaluate numerous alternative designs. Driving simulator studies have provided useful evaluations of dynamic message sign cycle time, guide sign designs, pavement marking designs, and work zone devices. These results have been implemented through traffic engineering guidelines and manuals. Typical traffic control device scenarios include normal driving, with and without other traffic present, in rural and urban scenes. Dependent variables include lane keeping, speed, reading time, comprehension, navigation to a specified destination, and subjective preference measures. Graphics resolution limits the ability of many simulators to render the fine detail of some traffic signs at realistic sizes and viewing distances. The dynamic range of projection and computer screens limits the ability of all simulators to accurately re-create a night-time driving environment and the luminance changes which occur with vehicle headlamps and retroreflective traffic control device materials.
