Issue/Challenge
The National Highway Traffic Safety
Administration (NHTSA) estimates
that 2.38 million people were injured
in traffic crashes on U.S. roadways
in 2022. Advanced driver assistance
systems (ADAS) in cars and trucks
have the potential to reduce traffic
crashes, prevent serious injuries, and
save thousands of lives each year. But
increasing safety on our nation’s roads
requires analysis of enormous amounts
of data from industry and government
stakeholders.
The Partnership for Analytics Research
in Traffic Safety (PARTS), a unique data-
sharing model, meets this critical need.
Members voluntarily share proprietary
and safety-related data with MITRE,
as the operator/integrator, knowing the
information is secure, aggregated, and
never used for competitive advantage.
MITRE’s Solution
As PARTS’ technical lead, MITRE
recently paired auto manufacturer
equipment information with police crash
report data covering 98 million vehicles
and 21.2 million crashes to identify trends
and the safety benefits and potential
limitations of ADAS technologies.
Nine major auto manufacturers—
Ford, Hyundai, General Motors, Honda,
Mazda, Mitsubishi, Stellantis, Subaru,

MERGING AUTO TECHNOLOGIES WITH
CRASH DATA SAVES LIVES ON U.S. ROADS
Auto manufacturer-government partnership meets critical need for data sharing and analytics.
and Toyota—and the U.S. Department
of Transportation’s NHTSA contributed
comprehensive datasets to MITRE for
analysis. It is the largest study of ADAS
to date.
Results
Our findings offer valuable insights
into how, where, and when ADAS
technologies are most effective—helping
automakers identify opportunities to adopt
best practices and make improvements
to manufacture and field safer vehicles.
Key insights from “A Study on
Real-world Effectiveness of Model
Year 2015–2023 Advanced Driver
Assistance Systems” include:
③ A 49% reduction in front-to-rear
crashes for vehicles equipped with
automatic emergency braking (AEB)
across all vehicle segments and
model years.
③ An improvement in AEB’s ability
to prevent rear-end crashes from
46% across model years 2015–2017
to 52% across model years 2021–
2023, translating into substantial
safety enhancements and economic
benefits.
③ A 9% reduction in single-vehicle
frontal crashes with non-motorists,
including pedestrians, cyclists,
scooters, and wheelchairs, for vehicles
equipped with pedestrian automatic
emergency braking (PAEB) systems.
Pedestrian crashes are among the
most severe forms of traffic crashes,
with deaths accounting for 18% of all
traffic fatalities, according to NHTSA.
