ADAS Crash Safety Analyses via OBMS Data


Project Goal:

To Perform empirical analyses of onboard monitoring system (OBMS) data from commercial motor vehicles (CMVs) to determine the safety impact of advanced driver assistance systems (ADAS).



The National Transportation Safety Board (NTSB), the Trucking Alliance, and other organizations have recommended the adoption of ADAS by motor carriers, touting the associated safety benefits. In September 2017, the American Automobile Association Traffic Safety Foundation (AAATSF) produced a series of reports titled “Leveraging Large- Truck Technology and Engineering to Realize Safety Gains.” However, while these reports corroborate the benefits of installing automatic emergency braking, air disc brakes, lane departure warning systems, and video-based onboard safety monitoring systems on large trucks, the benefits data are estimates based on past field operational tests with 50-150 trucks per test and anecdotal data from fleets.



The existing research on the potential safety benefits of ADAS does not rely on OBMS data. Currently there is only anecdotal and estimated data on the safety impact and effectiveness of ADAS systems. This research project will evaluate available OBMS data from ADAS-equipped CMVs to determine the safety impacts of ADAS. De-identified OBMS data will be obtained from vendors such as Lytx, SmartDrive, and Teledyne. This effort will use a dataset with billions of miles, thousands of trucks with and without ADAS, and tens of thousands of crashes that will provide empirical data on ADAS safety effectiveness and therefore be a substantial resource for fleets and State/Federal public sector decision makers.
