Project Abstract:
Autonomous vehicle (AV) stakeholders continue to seek assurance of the safety performance of this new technology through ways that include AV testing on in-service roads, AV-dedicated road networks and AV test tracks. Driving simulation can be used to test AV scenarios in a safe environment. This project proposes the use of a driving simulator to address specific issues associated with autonomous vehicles. The proposed research addresses five aspects associated with human take over from AV: (1) characterizing the level of risk in the driving environment, as a function of the traffic conditions, roadway design features, road environment conditions, and AV passenger attributes, (2) establishment of take-over warrants, that is, the given combinations of risk factors that will require take over, (3) take-over alerts, specifically, evaluating the efficacy of various alert alternatives: visual, auditory, tactile, and any combination of these, (4) assessing the propensity of an AV operator to take over the vehicle control, as a function of the nature of perceived risk and the prevailing levels of the risk factors (attributes of the driver, vehicle, the road design, and the road environment), (5) measuring and modeling the effective response time, in other words, the time taken for the operator to take over the vehicle (from the time of receipt of the AV’s alert to take over or the operator’s self-recognition of driving hazard without receiving alert) to the time the operator is in full control.
