PARTS: Market Penetration of Advanced Driver Assistance SystemsDecember 2021
The Partnership for Analytics Research in Traffic Safety (PARTS) is made up of automobile manufacturers and the U.S. Department of Transportation National Highway Transportation Safety Administration (NHTSA). Participants voluntarily share applicable safety-related data for collaborative safety analysis. The goal of this government-industry initiative, which is operated by MITRE as an independent third party, is to gain real-world insights into the safety benefits and opportunities of emerging advanced driver assistance systems (ADAS) and automated driving systems (ADS).
As of December 2021, participating automobile manufacturers submitted vehicle equipment data for approximately 47 million passenger vehicles sold in the United States—representing 93 different models from model years 2015–2020 and covering seven vehicle segments. Vehicle equipment data allows for the identification of various ADAS features that were present on the vehicle at the time of manufacture. This data is then merged with police-reported crash data provided by the NHTSA and used to analyze the effectiveness of ADAS features in real-world conditions. Because PARTS industry partners account for a large share of the U.S. automobile market, PARTS vehicle data can provide an improved understanding of how quickly ADAS systems are penetrating the U.S. car market.
This report provides key findings on penetration rates for several ADAS features. To learn more about PARTS, visit NHTSA.gov/PARTS.
