Summary
This paper presents a standardized procedure for validating fixed-base driving simulators, specifically addressing the need to verify their reliability for road safety studies and automotive development. The authors argue that while driving simulators offer significant advantages over real-world testing—such as safety and controlled conditions—rigorous validation is essential to ensure they accurately reproduce real behavioral environments. The study focuses on validating both absolute perceptivity (the ability to perceive motion and speed similarly to real driving) and relative perceptivity (the ability to respond to environmental changes, such as traffic volume, in a manner consistent with real-world behavior). The experimental design involved a comparative analysis between data collected from an instrumented vehicle driving on a real urban route and data collected from a fixed-base driving simulator reproducing the same route in virtual reality. The real-world tests utilized a Fiat Grande Punto equipped with an on-board diagnostic (OBD) interface to record kinematic parameters via the vehicle’s Controller Area Network (CAN) bus, including speed, steering angle, acceleration, and engine RPM. The simulator featured a static cockpit with a single front projection channel and a vehicle dynamic model developed in Matlab/Simulink. A sample of 93 volunteers, aged 18–35 and holding valid European licenses, performed driving tests on a 3.5 km urban route divided into eight homogeneous sections. For relative perceptivity validation, a subset of 47 drivers performed additional tests under varying traffic conditions. The validation methodology integrated conventional statistical tests (z-tests) with regression techniques. The z-tests compared instantaneous speed peak values between real and simulated drives to assess absolute perceptivity, while regression analysis quantified the systematic differences and behavioral variability between the two environments. The results indicated that residuals between simulated and real speed data followed a normal distribution. Statistical analysis revealed that the null hypothesis of no difference was rejected for six of the eight homogeneous sections, indicating statistically significant differences in absolute speed perception. However, the regression techniques successfully quantified these differences, demonstrating that the simulator reliably reproduced the relative variations in driver behavior caused by environmental changes. The study concludes that the proposed procedure, which combines statistical hypothesis testing with regression analysis, is an effective tool for validating fixed-base driving simulators. It allows researchers to not only detect differences between real and simulated driving but also to quantify the magnitude of these differences and evaluate the simulator’s potential for specific applications. The authors assert that this method has general validity and can serve as a standard protocol for validating similar simulation systems, ensuring that data derived from simulators are reliable for use in traffic safety research and vehicle subsystem development.
