The Automated Highway System (AHS) and The Intelligent Vehicle Initiative (IVI)

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

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

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

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

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

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
