Motor Vehicle Safety Challenge
• 32,719 highway fatalities in 2013 • 5.67 million reported crashes in 2013 • Leading cause of death for ages 4, 11-27
• Vehicle-to-vehicle communications technology can address a large majority of these crashes. Key types of crashes address by V2V include:
Rear-end and head-on collisions
Lane change related (blind spot warning)
Intersection related
Turning across path (left hand turns)

NHTSA Agency Decision on Light Vehicle V2V
"Vehicle-to-vehicle technology represents the next generation of auto safety improvements …" U.S. Transportation Secretary Anthony Foxx.
February, 2014
U.S. Department of Transportation Announces Decision to Move Forward with Vehicle-to-Vehicle Communication Technology for Light Vehicles
August, 2014 : NHTSA releases ANPRM and “Readiness Report” on V2V technology
May, 2015: “The Department wants to speed the nation toward an era when vehicle safety isn’t just about surviving crashes; it’s about avoiding them;”
“Connected, automated vehicles that can sense the environment around them and communicate with other vehicles and with infrastructure have the potential to revolutionize road safety and save thousands of lives.”

• Human drivers: – Over 90% of police reported crashes involve some type of driver error.
[http://www-nrd.nhtsa.dot.gov/pubs/812115.pdf]
• Safety benefits and potential: – Data indicates there are safety benefits for driver assistance systems,
i.e. “smart” technologies;
– NHTSA is researching to quantify the potential safety impacts for concept automation functions.
Safety Enhancement Opportunities

Automated Vehicle Levels
Level 0 No Automation
Level 1 Function- Specific Automation
Level 2 Combined Function Automation
Level 3 Limited Self-Driving
Level 4 Full Self-Driving Automation
No steering or braking/ throttle control e.g. crash warning systems
Braking/Throttle or Steering control, but not in combination e.g. automatic braking systems
• Integration of braking, throttle, and steering control • Driver available at all times to retake control
• Integration of braking, throttle, and steering control • Driver expected for occasional control • Driver can cede full monitoring and control authority
• Integration of braking, throttle and steering control • Driver NOT expected for control • Safety of operation is solely handled by the vehicle
• A Research Framework!

• Still much room to improve
• Need realistic safety impact metrics to guide priorities
• “Safety enhancement” versus “Safety preservation”
Focus on Safety is essential
• Human factors Principles around control handoff; Driver engagement in the driving task; potential misuse, abuse, unreasonable risk taking
• System requirements; functional safety requirements; impacts of levels
• Artificial Intelligence complexity and sufficiency
• Objective test procedures; Test domain for reasonable assurance
• Cybersecurity needs; Software safety assurance needs
Various key Challenges remain
• Automated Vehicles; Automotive Cybersecurity; Electronics Reliability
