Peer-to-Peer Networking... For Traffic

"A German research project on show at hi-tech trade fair Cebit envisions a peer-to-peer network for vehicles on a road passing data back and forth. Cars or bikes experiencing problems would pass data that would ripple down the chain of vehicles behind them."

"...For example, cars could spot oil on the road by combining temperature readings with wheel traction information. A wheel slipping on the road even though the temperature was not low enough for frost or ice would suggest oil or another slippery substance was present. Once a car detected this sort of danger, information about it would be generated and passed down the line of vehicles approaching the patch of oil."

"...The SmartWeb project is being co-ordinated by the German Research Center for Artificial Intelligence but has 16 other partners including BMW, Siemens, Daimler Chrysler, Deutsche Telekom and the European Media Lab."
