Summary
This paper summarizes three studies conducted at the Western Transportation Institute (WTI) to demonstrate the utility of immersive driving simulators for the formative evaluation of engineering designs and human factors issues. The authors argue that iterative evaluation using high-fidelity simulations allows for cost-effective validation of design concepts and user interfaces before physical implementation. The WTI laboratory utilizes a DriveSafety® 500C fixed-base simulator featuring a 160-degree field of view, physics-based vehicle dynamics, and eye-tracking capabilities to replicate realistic road geometries, traffic flows, and driver perception tasks. The first study evaluated Intelligent Transportation System (ITS) deployments on US Highway 191, a rural highway with frequent crash clusters attributed to speed variance and distraction. Fifteen drivers were tested in scenarios with no posted speed limits, a 60-MPH limit, or a 50-MPH limit displayed on dynamic message signs (DMS). Results indicated that drivers with no limit and those with a 60-MPH limit exhibited similar speeds (85th percentile speeds of 53.15 MPH and 53.65 MPH, respectively). However, drivers exposed to the 50-MPH limit reduced their speeds by approximately 6 MPH (85th percentile speed of 47.65 MPH), with greater reductions observed on straight sections than on curves. Simulator speeds correlated well with real-world spot speed studies, validating the simulation’s realism. The second study assessed human factors principles of haptic and auditory cues for lane departure warning systems. Fifteen drivers performed a secondary task while a simulated wind gust caused lane departures. Warnings were delivered via haptic (seat vibration), auditory (alarm), or combined modalities. Haptic warnings produced significantly faster reaction times than auditory or combined warnings. Auditory warnings resulted in more erratic steering responses and longer times to return to a steady state. Approximately 27% of participants initially corrected toward the centerline (potentially into oncoming traffic) regardless of the warning mode. While haptic warnings were the least annoying and most effective for safety, the combined modality was the most preferred by users. The third study evaluated a Cooperative Advanced Warning System (CAWS), which uses flashing pink strobe lights to alert drivers to hazards such as pedestrians or animals. Thirty drivers were tested in scenarios involving hazards, with half receiving prior training on the CAWS system. In a nighttime rural scenario involving a deer herd, 64% of untrained drivers collided with the hazard, compared to only 20% of trained drivers. Trained drivers began slowing significantly earlier, maintaining a mean approach distance of 24.1 meters versus 5.6 meters for the control group. The findings highlight that training is critical for the effectiveness of cooperative warning systems. The authors conclude that immersive simulation is a valuable tool for the formative evaluation of transportation infrastructure and safety systems. It enables the safe, controlled testing of innovative designs and user interfaces, allowing for the identification of negative aspects and the refinement of concepts before real-world deployment.
