As part of a comprehensive program to explore driver-vehicle system response in lateral steering tasks, describing functions and dynamic data have been gathered in several milieu. These milieu include a simple fixed-based simulator with only an elementary roadway delineation display; a fixed-based statically operating automobile with terrain displayed by a wide-angle projection system; and a full-scale moving-base automobile operating on the road. Dynamic data with the two fixed-base simulators compared favorably and implied that the impoverished visual scene, lack of engine noise, and simplified steering wheel characteristics in the simple simulator did not induce significant driver dynamic behavior variations. The fixed-base versus moving-base comparisons showed that the moving base had substantially greater crossover frequencies on the road course; this frequency can be ascribed primarily to a decrease in the driver's effective latency. When considered with previous data, the moving-base full-scale versus fixed-base simulator differences are ascribed primarily to the motion cues present on the road course rather than to any visual field differences. /Author/
