“…An example of the first type of evidence would be total number of safety errors or demerit points in one platform shows significant positive correlations with comparable measures in the other platform [ 7 ]. An example of the second type of evidence would be to show similar inferences for any between-subject characteristics such as age group [ 4 ] and within-subject differences such as reduced driving safety while distracted compared to baseline driving [ 8 ]. In this second case, relative validity can be understood as replication of findings across the two platforms for similar performance metrics.…”

Forty-two younger (Mean age = 35) and 37 older drivers (Mean age = 77) completed four similar simulated drives. In addition, 32 younger and 30 older drivers completed a standard on-road drive in an instrumented vehicle. Performance in the simulated drives was evaluated using both electronic drive data and video-review of errors. Safety errors during the on-road drive were evaluated by a certified driving instructor blind to simulator performance, using state Department of Transportation criteria. We examined the degree of convergence in performance across the two platforms on various driving tasks including lane change, lane keeping, speed control, stopping, turns, and overall performance. Differences based on age group indicated a pattern of strong relative validity for simulator measures. However, relative rank-order in specific metrics of performance suggested a pattern of moderate relative validity. The findings have implications for the use of simulators in assessments of driving safety as well as its use in training and/or rehabilitation settings.
