This report summarizes work on developing simulation databasing tools and procedures to support driving human factors experiments. The simulator requirements are specified, and a complete description of the resulting Iowa Driving Simulation facility are provided. The specification and description of the visual features of the ORCHIDS data base illustrate the capabilities generated. Subsystems necessary to support simulation are described. Experimental design procedures are outlined. An example scenario illustrates the potential for applying driving simulation as a research tool to examine driver performance and vehicle design issues.
