Summary
This report evaluates the performability of five draft research test procedures developed by the National Highway Traffic Safety Administration (NHTSA) to assess the test track performance of Advanced Driver Assistance Systems (ADAS). The study addresses the need to verify that these procedures—released in November 2019 under Docket No. NHTSA-2019-0102—can be executed as written without ambiguity. The five systems evaluated are Active Park Assist (APA), Intersection Safety Assist (ISA), Blind Spot Intervention (BSI), Traffic Jam Assist (TJA), and Opposing Traffic Safety Assist (OTSA). The experimental design utilized two subject vehicles: a 2017 Mercedes-Benz E300 for APA tests and a 2019 Audi A6 for the remaining evaluations. Tests were conducted at the NHTSA Vehicle Research and Test Center using robotic steering and brake/accelerator controllers, inertial/GPS data collection, and surrogate pedestrians. The APA assessment involved automated parking maneuvers into perpendicular and parallel spaces, including scenarios with encroaching pedestrians, obstructing vehicles, and manual system overrides. The ISA evaluation tested responses to principal other vehicles in intersection scenarios, though speeds were reduced to 6 mph to accommodate the Audi’s system limits. BSI tests assessed lane-change interventions with constant or closing headways, while TJA trials evaluated car-following behaviors in low-speed scenarios. OTSA tests examined responses to unintended and intended lateral deviations toward oncoming traffic. The results indicated that all five draft procedures were performable and satisfied specified validity conditions. For APA, the Mercedes-Benz successfully detected pedestrians and obstructing vehicles but failed to meet performance criteria for system override tests, often failing to abort or stop correctly. ISA interventions occurred in only one crash-imminent scenario; the report recommends adding acceleration tolerances for vehicles moving from rest, as none were specified in the draft. BSI tests yielded no activations because the system was inadvertently disabled by the deactivation of a related lane departure feature, highlighting the need for careful vehicle configuration. TJA performance was largely successful, with the Audi avoiding collisions in most trials, though one impact occurred during a complex lane-change braking scenario. OTSA tests were performed as described, though the Audi lacked the specific OTSA hardware, resulting in no expected interventions. The study concludes that the draft procedures are technically viable for research purposes. However, it identifies specific areas for refinement, such as the need for acceleration tolerances in ISA tests and the importance of verifying ADAS enablement states to prevent confounding results. These findings support the continued development of standardized testing protocols for ADAS technologies.
Key finding
All five draft research test procedures for ADAS technologies were found to be performable with all validity conditions satisfied, though a tolerance for vehicle acceleration during intersection safety assist tests starting from rest is recommended.
