AHS – The Vision
![Page 3: AHS – The Vision](https://reader036.fdocuments.net/reader036/viewer/2022081504/568134b8550346895d9bd6f8/html5/thumbnails/3.jpg)
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)
![Page 4: AHS – The Vision](https://reader036.fdocuments.net/reader036/viewer/2022081504/568134b8550346895d9bd6f8/html5/thumbnails/4.jpg)
AHS – The Vision (California Style)
• Dedicated AHS lanes
• Cars following in closely spaced platoons
• Automated merging / diverging
• Increased lane capacity x 2

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

AHS Platooning Concept
AHS Lane
Regular Lane

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

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

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

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

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

IVI Technology
• Deployment is a big issue– Public infrastructure versus private system
• Chicken and egg problem
![Page 23: AHS – The Vision](https://reader036.fdocuments.net/reader036/viewer/2022081504/568134b8550346895d9bd6f8/html5/thumbnails/23.jpg)
VII
• To help make IVI technologies work better we need intelligence in the road as well as in the vehicle

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?
