Global Comm Net May Reduce Emissions

A global communications technology by Cohda Wireless and researchers at the University of South Australia combines Wi-Fi and GPS technology in a system called dedicated short-range communications. The company believes that this idea could curb vehicular emissions by more effectively managing traffic.

But Cohda says the technology could be road-ready by 2012. It already has conducted 700 field trials in Australia, the United States and Italy, and it recently demonstrated the system for automakers and government officials Down Under. A $1.5 million field trial involving 200 cars is slated within two years...

Dedicated short-range communications uses Wi-Fi and GPS to share data with a centralized location and other vehicles via external Wi-Fi spots, effectively making each car a node on the network

A similar effort is underway in the United States; the system is called an Intelligent Transportation System where cars talk to each other and to us in a network designed to increase safety, reduce congestion and manage traffic.

SF fans may recall the ATMOS (Atmospheric Omission System) from The Sontaran Strategem - a Doctor Who episode originally broadcast in 2008.

ATMOS is marketing a satellite navigation system developed by child prodigy Luke Rattigan (Ryan Sampson). The system also reduces carbon dioxide emissions to zero; UNIT requested the Doctor's help because the technology is not contemporary and potentially alien.
