Drowsy & Distracted Drivers
• National Highway Traffic Safety Administration (NHTSA) estimates that approximately 100,000 police-reported crashes annually (about 1.5% of all crashes) involve drowsiness/fatigue as a principal causal factor
• A conservative estimate of related fatalities is 1,500 annually or 4% of all traffic crash fatalities.
• At least 71,000 people are injured in fall-asleep crashes each year.
• NHTSA estimates these crashes represent $12.5 billion in monetary losses each year.

Drowsy & Distracted Drivers
Sleepiness leads to crashes because:
• Slower reaction time
• Reduced vigilance
• Deficit’s in information processing

NHTSA NCAP Proposal
Investigate rating system for crash avoidance technologies
• A step beyond Passive Safety only rating
Primarily address the four most significant crash modes
• Run off road – 27% MAIS 3+ injuries• Rear End – 19% of MAIS 3+ injuries• Lane change – 6% of MAIS 3+ injuries• Crossing path (intersection) – 30% of MAIS 3+ injuries
Recognition of Active Safety Technology

Integrated Safety
• Driver support & collision mitigation will drive advanced sensor development, but….
• The greatest opportunity for the future is driven by combining Active Safety Systems & Passive Safety Systems
Passive Safety will still be the dominating system in saving lives for the foreseeable
future

Integrated Safety Priorities
• Maintain safe speed & distance
• Stay in lane and avoid dangerous passing maneuvers
• Safely pass intersections
• Avoid collisions with vulnerable road users
• Reduce severity of accidents
• Improve occupant protection beyond current ratings and regulations

Integrated Safety
Sensing• How do we know we have an issue?
• Driver• Drowsiness, alcohol, attention to the road
• Vehicle• Lane Departure, collision warning, path estimation, GPS tracking, stability, closing velocity
Actuation• What do we do about it?
• Reduce driver workload/ increase awareness• Night Vision, Speed Sign Recognition, Intersection Awareness, Adaptive cruise control,
Queue assist, blind spot detection, Stop & Go
• Warn driver – raise awareness of Drowsiness issue• HMI, buzzers, chimes, lights, haptic warning on seat belts, vibrating seat, vibrating steering
wheel, pedal resistance
• Take action – vehicle control• Stability control, collision mitigation by braking, Safety System pre-trig

NCAP Proposals
Highlight Crash Avoidance Technologies to the consumer – what is the benefit?Crash Avoidance rating
• Option 1 – 1 grade for each technology adopted (e.g. C grade for 1 technology, B grade for 2 etc)
• Option 2 – Letter grade based on total points earned using assigned weighting (points) for each technology according to its overall effectiveness
