The "Yamaha ASV-2" is a motorcycle
developed to realize the functions to be compatible with the "Intelligent
Transport Systems" (ITS) to be implemented sometime in the
early part of the new century with the aim of "constructing
systems that integrate people, roads and vehicles.
Yamaha has put to use the latest in electronics and other technologies
to build on existing safety technologies in the research and development
of this vehicle.
Model 1 of the Yamaha ASV-2 mounts five new systems that fall under
the three categories of preventative safety, accident avoidance and
damage mitigation.
Model 2 mounts a road-vehicle collaborative system that can handle
six types of rider support systems based on information supplied
by the road infrastructure.
The Yamaha ASV-3 is based on the technologies developed for its predecessor,
the Yamaha ASV-2, an Intelligent Transport Systems (ITS)-compatible,
research-use vehicle with an airbag system, announced in 2000.
However, the Yamaha ASV-3 features a new, more advanced airbag system
for improved crash safety, being developed using a variety of analysis
software programs.

| HMI description |
In the areas of intersections, the motorcycle
actively transmits a signal to 4-wheeled vehicles in the area to
inform the drivers of the presence or approach of a 2-wheeler with
the aim of preventing misjudgments or failures to anticipate 2-wheeler
movement on the part of the 4-wheeler's driver.
This system consists of a marker located on the approach to an intersection
(approx. 100 meters before) and an infrared laser communications
unit mounted on the front of the 2-wheeler and the 4-wheeler.
As the motorcycle passes the marker it receives a signal indicating
the distance to the intersection, which is used along with data of
the motorcycle's own traveling speed to calculate and transmit the
traveling time (vehicle interval time) to the intersection The 4-wheeler's
system receives this "vehicle interval time" information
and generates information and a warning to the 4-wheeler's driver
to aid in making the proper decision about whether to stop or proceed.
The system also functions to give the 4-wheeler driver a warning
if there is danger of a collision resulting from the driver's failure
to recognize the presence of a 2-wheeler approaching from behind
when the 4-wheeler is about to make a left turn at an intersection.
