Testing environment and verification procedure for in-car tasks with dynamic self-paced driving scenarios

The Visual-Manual NHTSA Driver Distraction Guidelines for In-Vehicle Electronic Devices were published in 2013. The NHTSA testing scenario comprises of driving with a steady speed on a straight highway while keeping a constant distance to a lead vehicle. However, the distraction effects of, for instance, navigation aids cannot be reliably tested within the scenario. Real-world driving scenarios with guidance include turns as well as lane selections with the associated deceleration and acceleration behaviors. In addition, the safety risk of a 2-second in-car glance (NHTSA criterion) is highly dependent on the driving speed. Consequently, we created an alternative test environment and in-car glance duration verification criteria for dynamic and self-paced driving scenarios. By the means of visual occlusion, we collected the preferred occlusion distances of 97 drivers with varying backgrounds in a driving simulator simulating real Finnish suburban and highway roads. The results indicate that for each point of the road, it is possible to define occlusion distances that drivers are not willing to exceed while fully concentrating on the driving. We show that these dynamic verification limits and the generic method can be used for testing in-car tasks in dynamic driving scenarios where the drivers can freely adjust their speeds.
