| Abstract | This project investigated how driver expectations about Level 2 ADAS systems affect driver engagement and performance. Many vehicles available to consumers offer some level of automated driving functionality, but the capabilities of these vehicles vary widely among makes and models. Drivers may have preconceived expectations about how these driver assistance systems function. This project tested 96 participants in low- and high-capability SAE Level 2 vehicles. Participant training evaluated if driver was in agreement with the vehicles actual capabilities (high or low) or not (i.e., they were told the vehicle had highly functioning ADAS systems when it fact it only had low, or vice versa). Testing was conducted on both public roads and on the Virginia Smart Road test track. While on the test track, participants were asked t completed non-driving tasks while driving, and mid-way through the driving session experienced a surprise event (crash imminent scenario). |
