| Summary |
|
Following the AHS Demo '97 in San Diego, the Department of
Transportation (DOT) announced the Intelligent Vehicle Initiative (IVI)
program and is promoting four types of platform (passenger vehicles, commercial
vehicles, public transit vehicles and special vehicles). In this demo, 15
American organizations and companies participated and held demonstrations
of free performances with commercial vehicles, special vehicles such as
snowplows, passenger vehicles (vans and sedans), and others. |
[Key Demo Features]
(1) 3M Intelligent Transportation Systems
Vehicles are guided to a designated path even in poor visibility using magnetized
marking tape embedded with magnetic data. Although the magnetic field of the
tape is weak, it can emit signals continuously and can be detected six to 18
inches from the road surface. It can be used for white or yellow lines, etc.,
for possible combination with camera detection. The demo proved the tape's easy
installation as an infrastructural element and showed a sufficiently high level
of position maintenance, accuracy, etc.

(2) California PATH Program
The California PATH project was established jointly by the University of California
at Berkeley and the California Transit Authority. The objective of the project
is to realize far-reaching improvements to surface transportation systems through
the development and evaluation of ITS. Using ultra-sensitive magnetic marker
guidance systems, PATH demonstrated a system for passenger vehicles that indicates
proper distances for stopping cars. In partially hidden locations such as those
just ahead of a curve, this system was able to reproduce precision within centimeters
in judging distance from the curb. This performance will be essential for realizing
the precise control of stop positions for passenger buses in future.

(3) Freightliner Corporation
Freightliner held a demo of its electronic break system and lane departure warning
system. With cameras, image processing and lane recognition algorithms, lane
departure caused by driver inattention was detected and an alarm was set off
whenever divergence took place.

(4) MnDOT/University of Minnesota Vehicle
DOT of Minnesota performed a snowplow demo with a vehicle equipped with the
latest technologies in DGPS, magnetic lateral guidance and advanced radar collision
warning systems. The demo was conducted through coordination among the University
of Minnesota, 3M, Altra Technologies and Navistar-International.

(5) Ohio State University
Lane, vehicle, and tag position location using image processing and radar were
demonstrated. This detection system uses recognition of patterns in the forward
screen to perform automatic driving. The university also demonstrated ACC, high-curvature
steering and lane changing using safe speed control, and advanced vehicle control
based on Global Positioning System (GPS) and a map database. There were also
demos by AssistWare Technology, the National Highway Traffic Safety Authority,
and the Federal Highway Administration.
