AHS


The Vision

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)

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

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

Human factors is a big deal


Do people trust the technology


Will people over

compensate for the
technology (or misunderstand its capabilities)

Deployment is a big issue


Public infrastructure versus private system
