Familiarization with a Forward Collision Warning on driving simulator: cost and benefit on driversystem interactions and trust

Abstract : Introducing Advanced Driver Assistance Systems (ADAS) into the vehicle could improve drivers’ comfort and reduce road crashes. However, suitable methods are required to study driver/system interactions. In fact, ADAS generate critical use cases, i.e. situations where alarms, or absence of alarms, can be negative for safety. The present study aimed at evaluating the impact of getting familiar, by means of a driving simulator, with critical situations when using the Forward Collision Warning system (FCW). We hypothesized that experiencing the system’s function in critical situations would improve drivers’ performance and their trust in the FCW. We compared judgments and driving performance of three independent groups: a “control group” where drivers did not use the FCW, an “unfamiliarized group” where drivers used the FCW without having been familiarized with the system, and a “familiarized group” where drivers used the FCW after having been familiarized. Results showed that familiarization made driver/system interactions more effective and safer. Moreover, familiarized drivers rated the system more positively than unfamiliarized drivers. However, familiarization decreased drivers’ self-confidence and did not prevent from haste when overtaking slow vehicles. We discussed the relevance of using a driving simulator in FCW’s studies and the possibility to transfer skills and knowledge to field operational tests. Finally, we proposed possible improvements to make the familiarization with the system still more effective.
