Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating the Oregon State University Driving Simulator based on speed, acceleration, and deceleration data. The validation effort consisted of a road test and a simulator test. The road test was completed on a five-lane urban principal arterial in Corvallis, Oregon, and the simulated environment matched the field conditions as closely as possible. Ten subjects participated in both tests. Minimum speed, maximum speed, average speed, 85th-percentile speed, maximum acceleration and maximum deceleration data variables were analyzed using graphical comparisons as well as two-sample paired t-tests. With the exception of minimum speed, all data variables showed statistically significant differences on at least one of the three test sections. However, the researchers considered the magnitude of these differences to be insignificant in a practical setting (on average, 3.5 mph for speed variables and 0.80 ft/s�� for acceleration and deceleration variables). Thus, the results of this research confirm the validity of the OSU driving simulator with regards to speed and acceleration. / Graduation date: 2013
