1. Automated Highway System (AHS) Intelligent Vehicle Initiative (IVI) Vehicle Infrastructure Integration (VII)

2. AHS – The Vision

3. 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

21. 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

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

23. VII To help make IVI technologies work better we need intelligence in the road as well as in the vehicle

24. VII Chicken and egg problem: –What gets built / deployed first? How does the public pay for the purchase, installation, and operation of the public’s portion of the infrastructure?
