Concerning those services under advanced vehicle safety systems, a series of collision
avoidance systems would be developed. For potential longitudinal, lateral, and intersection
collisions, the systems would be able to sense impending trouble, warn the driver, and
temporarily control the vehicle. On attempted lane changes, the driver’s blind spot
would be monitored, and the vehicle prevented from making the switch if a vehicle was
present. Another possibility is vision enhancement for the driver, in which the roadway
and roadside are continuously scanned for potential hazards and the driver is made aware
of situations when necessary. In-vehicle equipment can be used to monitor the driver’s
condition and issue appropriate warnings. In employing precrash restraint deployment,
the velocity, mass, and direction of the vehicles and objects involved in a potential crash
are identified and the number, location, and physical characteristics of occupants are
determined. This information in turn is used to trigger responses, such as tightening of
lap-shoulder belts, arming and deploying air bags at optimal pressure, and deploying roll
bars. Another program being investigated is automated vehicle operation. This would
ultimately provide an accident-free environment on the roadway. Drivers would be able
to buy a vehicle already equipped to drive under these conditions, or purchase instrumentation
and have it installed on an existing vehicle.
