Summary

This report evaluates the efficacy of driving simulators as a training tool for ground-vehicle operators at airports, specifically to reduce vehicle-pedestrian deviations (VPDs) and improve runway safety. Sponsored by the Federal Aviation Administration (FAA) and conducted by the Volpe National Transportation Systems Center, the study addresses the challenge of training authorized drivers who often cause incursions due to disorientation, unfamiliarity with airport layouts, or misinterpretation of signs. The research aimed to determine if simulator-based training could effectively replace or supplement conventional methods, which typically involve lengthy passenger rides with experienced operators, by offering a safer, more cost-effective alternative for practicing spatial awareness and operational procedures. The evaluation focused on a simulator facility at Minneapolis-St. Paul International Airport (MSP), featuring a generic truck cab with a 150-degree field of view and realistic controls. The methodology comprised two main phases: simulator validation and training assessment. Validation studies compared the virtual environment against the real-world airport surface across four dimensions: visual accuracy, position and information awareness, navigation, and distance legibility. Visual accuracy was assessed via expert opinion from experienced drivers, while position awareness and navigation were measured using performance-based tasks. In the "drop-point task," participants were placed at various locations (e.g., taxiway intersections, runways) in both the simulator and a real vehicle to answer questions regarding their spatial orientation, landmarks, and signage. Navigation tasks involved route-finding exercises. Additionally, the study evaluated training outcomes for both inexperienced and experienced drivers, analyzing the impact of structured simulator practice on procedural retention and safety awareness. The findings indicated that the simulator provided sufficient fidelity for training purposes, though it was not a perfect replica of reality. Participants demonstrated high levels of position and information awareness in both environments, with only slightly better performance observed in the real world. The visual accuracy was deemed adequate for training, provided trainers were aware of specific discrepancies, such as sign placement errors, which could be mitigated during instruction. However, the distance legibility task revealed limitations in the simulator’s graphics, highlighting that perfect visual replication is not necessary if the specific training objectives do not require long-distance reading. Regarding training efficacy, the simulator proved valuable for inexperienced drivers by facilitating structured practice of infrequently used procedures, aiding memory and execution. For experienced drivers, the simulator offered meaningful scenarios for advanced training, allowing them to safely experience complex or dangerous situations, thereby increasing situational awareness. The study concludes that driving simulators are a viable component of comprehensive ground-vehicle operator training programs, offering significant safety and cost benefits over traditional methods. It emphasizes that simulator fidelity requirements should be tailored to specific training goals rather than seeking universal perfection. The report also addresses simulator sickness, recommending strategies such as minimizing session duration, gradually increasing exposure, reducing navigation speed, and ensuring participants have active control over movement. Finally, the authors suggest future research into low-cost simulator hardware, investigating whether reduced field-of-view displays or simplified controls like joysticks could achieve comparable training outcomes, potentially lowering the barrier to entry for airports seeking to implement such safety programs.

Key finding

Simulator-based training for inexperienced drivers significantly improved performance on specific procedures, and validation studies confirmed the simulator's fidelity was sufficient for training spatial awareness and navigation tasks comparable to real-world performance.
