  1. The Automated Highway System (AHS)andThe Intelligent Vehicle Initiative (IVI)

  2. AHS – The Vision

  3. AHS – The Vision • Removal of human error from the task of driving • Efficiency improvements (increased flow) • Safety improvements (decreased accidents) • Environmental improvements (decreased fuel use and emissions)

  4. AHS – The Vision (California Style) • Dedicated AHS lanes • Cars following in closely spaced platoons • Automated merging / diverging • Increased lane capacity x 2

  5. AHS – The Vision • HOW? • Technology to allow removal of reaction time and distance • Decrease in following distance = increase in capacity • Safety maintained by technology • Internal platoons = low speed differential crashes • Space between platoons = decrease in severity of crash between platoons

  6. AHS Platooning Concept AHS Lane Regular Lane

  7. AHS – The Technology • Automated Check-in • Automated Check-out • Lateral and Longitudinal Controls • Malfunction Management and Analysis • Commercial (& transit) Vehicle Needs • Deployment Issues

  8. San Diego Tests • Mandated by Congress • Took place in San Diego in 1997 on a barrier separated HOV lane • Systems built by Automated Highway Systems Consortium • A partnership between government / universities / car companies

  9. San Diego Test • Results • AHS is feasible • AHS is not currently practical • Various AHS technologies are marketable • AHS technologies have significant positive safety implications

  10. Intelligent Vehicle Initiative • The result of the AHS Findings • Very heavy safety orientation • Use new technology on roadside and in vehicles to make roadways safer

  11. IVI Technologies • Currently on the market • ABS (Anti-lock braking systems) • Night vision systems • GPS • Adaptive cruise control • Front end collision warning systems • Automated mayday systems

  12. IVI Technologies • Future Systems (under active development) • In-vehicle signing of • Dangerous conditions • Approaching emergency vehicle • Side collision avoidance systems • Rear object warning systems • Lane departure warning systems

  13. IVI Technologies • Future Technologies (continued) • Remote control vehicles • Snow plows • “Guard” vehicles for maintenance (unmanned crash attenuator vehicles) • Multi-vehicle “trains” (1 driver, multiple vehicles) for commercial trucks on barrier separated roads

  14. IVI Technologies • Future Technologies (continued) • Drowsy driver recognition • Intoxication detection • Automated steering control • Automated collision avoidance • Lane following • Obstacle recognition • Intersection collision warning systems

  15. IVI Technologies • Human factors is a big deal • Do people trust the technology • Will people over-compensate for the technology (or misunderstand its capabilities) • ABS • 4-wheel drive in the snow

  16. IVI Technology • Deployment is a big issue • Public infrastructure versus private system • Chicken and egg problem
