| Date | 7-12 August 1997 | |
| Venue | Interstate 15 (HOV Lane), San Diego Miramar Community College, SanDiego, USA | |
| Organized by | National Automated Highway System Consortium (NAHSC) | |
| Total participants | 3,500 (1,350 tested demo vehicles) | |
| Summary | An open real-road demo was organized as the final-stage study of automated cruising technologies developed under the R&D program of NAHSC under the Intermodal Surface Transportation Efficiency Act (ISTEA). The course was a 7.5-mile stretch of the HOV lane (lane reserved for vehicles with two or more passengers during rush hours) on Interstate 15 running north-south through San Diego, California. |

[Key Demo Features]
(1) Multi-platform (CMU/GM/Houston Metro)
Demos on lane changing, headway maintenance, and obstacle evasion using video
cameras and radars were organized using two buses, two passenger vehicles, and
one minivan.
In lane detection with compact camera, shortcomings in the precision of image
readings were adjusted using a processing system to realize high-precision lane-keeping.
Multi-Platform
(2) Platooning (UC Berkeley/GM Buick)
Eight passenger vehicles started up simultaneously from the stop position, maintainings
a headway of 6.4 meters (constant regardless of vehicle speed) and accelerating
to up to 100 km/h. In another demo, the second vehicle in the platoon diverged
from the queue, changed lanes, decelerated and took a new position at the tail
end for continued platooning. The test aimed at platooning to increase traffic
volume per hour and involved lateral lane control using magnetic nails as well
as headway and speed control using radar and vehicle-to-vehicle communication.
Plattoning
(3) Commercial Vehicle-Truck (Eaton Vorad)
The demo involved a passenger vehicle (without AHS) and a truck (with AHS) and
combined microwave-based front and back headway control already available on
the market using headway control for collision prevention based on the millimeter-wave
radar expected to be used in the future. The passenger vehicle driving at different
positions around the truck was detected by radar on the truck and this information
communicated to the truck driver.
Commercial Vehicle-Truck
(4) Control Transition (Honda R&D North America)
Demos were held on Adaptive Cruise Control (ACC) and obstacle evasion. Magnetic
nails and image-based lane detection utilizing video cameras were used to control
steering for lane-keeping. Switching between automated cruising and manual driving
was also demonstrated.

Among others were demos on Maintenance, Radar Reflective Technology, Evolutionary Deployment, etc.
