It happens every time traffic gets too heavy and starts to slow: One
inattentive driver panics and slams on his brakes, triggering a chain
reaction that leads to a complete traffic stoppage a few dozen cars
behind. If everyone could just slow down, pay attention, and maintain an
even speed, we could all get where we're going.
Honda hopes to deploy a new system to help make that a reality.
The Japanese automaker has developed the first-ever vehicle
communications system geared to cut both traffic jams and fuel use by
monitoring a driver's acceleration and braking habits and providing
information that Honda says will encourage smoother driving.
Honda, along with the University of Tokyo's Research Center for Advanced
Science and Technology, has developed on-board terminals that connect
to cloud-based computing systems to allow communications between cars on
the same road that can help drivers maintain a relatively constant
driving distance between vehicles. Tailgating is bad for both traffic
and fuel economy, and Honda's system discourages it.
The system differs from traffic monitoring systems that have been part
of other vehicle communication systems in that it provides colour-coded
displays to indicate whether the driver needs to drive smoother and make
acceleration and deceleration more gradual. The system can also work
with adaptive cruise control to automatically regulate speed among a
group of vehicles. The first public road tests will occur in Italy and
Indonesia starting in May of 2012. Honda says the system can boost
average speed by 23 per cent and increase fuel economy by eight per
cent. Not bad for some cloud computing.

Honda Develops World's First Technology to Detect the Potential for Traffic Congestion With the Goal to Prevent Traffic Jams
Public-road Testing to Begin in May 2012
TOKYO, Japan, April 26, 2012 - Honda Motor Co., Ltd. announced the
successful development of the world's first*1 technology to detect the
potential for traffic congestion and determine whether the driving
pattern of the vehicle is likely to create traffic jams. Honda developed
this technology while recognizing that the acceleration and
deceleration behavior of one vehicle influences the traffic pattern of
trailing vehicles and can trigger the traffic congestion.
In conjunction with the Research Center for Advanced Science and
Technology at the University of Tokyo, Honda conducted experimental
testing of a system utilizing the technology to detect the potential for
traffic congestion. The test results demonstrated that the system
helped increase the average speed by approximately 23% and improved fuel
efficiency by approximately 8% of trailing vehicles.
With the goal to bring this technology to market, Honda will begin the
first public-road testing of the technology in Italy and Indonesia in
May and July of this year, respectively, to verify the effectiveness of
the technology in minimizing vehicle congestion.
Rather than providing information to help the driver avoid existing
congestion based on current traffic information, the system monitors the
acceleration and deceleration patterns of the vehicle to determine
whether the driver's driving pattern is likely to create traffic
congestion. Based on this determination, the system provides the driver
with appropriate information, including a color-coded display through
the on-board terminal, to encourage smooth driving which will help
alleviate the intensity of acceleration and deceleration by trailing
vehicles, thereby helping to prevent or minimize the occurrence of
vehicle congestion.
Moreover, the positive effect on minimizing congestion and fuel
efficiency improvement can be further increased*4 by connecting the
on-board terminals to cloud*2 servers to make the driver aware of and in
sync with the driving patterns of vehicles ahead by activating the ACC
(Adaptive Cruise Control)*3 system at the right time to maintain a
constant distance between vehicles at the most appropriate interval.
Traffic congestion causes not only a delay in arrival time but also an
increase in CO2 emissions and a higher potential for rear-end
collisions. Striving to realize "the joy and freedom of mobility" and "a
sustainable society where people can enjoy life," as stated in the
Honda Environmental Vision, Honda will work toward the establishment of a
congestion-free mobility society all around the world.
