"A driver may not even be able to see a vehicle, but their car
can communicate with it," said Don Grimm, senior researcher for
General Motors' Perception and Vehicle Control Systems group.
"Say a vehicle ahead of you encounters an obstacle. It can
communicate that and provide the driver with a heads-up to avoid
a collision." The idea is to give vehicles, bicyclists and even
pedestrians sensors that can communicate wirelessly with each
other. If an integrated network knows all of their locations, it
can keep vehicles and people from running into each other.
Vehicle-to-Vehicle (V2V) "Wi-Fi" allows vehicles to communicate
with each other and roadside sensors independently of a network.
Additional Vehicle-to-Infrastructure (V2I) sensors would
contribute real-time road conditions, stop light status, and
accident locations to route traffic efficiently, or with the
help of automatic braking systems, bring vehicles to a halt. To
pilot this type of system, the University of Michigan, eight
automakers and Department of
