Trenton,NJ,USA -Courier Post On Line, by MIKE FRASSINELLI -4 Oct 2010: ... Motorists on the state's New Jersey Turnpike and the Garden State Parkway, will be provided high-tech traffic "forecasts" to alert them about potential bottlenecks before they happen. Using complex computer models that have been said to predict traffic flows with up to 93 percent accuracy, the Turnpike Authority plans to put its new "Traffic Prediction Tool" into use early next year... Drivers would see the forecasts on existing highway message signs or via e-mail or text. Motorists get real-time alerts now, but the traffic forecast has the ability to predict congestion before it happens, based on traffic patterns detected by transponders and road sensors, as well as historical traffic patterns... The highway agency has already run live models of the forecasts, with encouraging results... The technology is already in use in Singapore and Stockholm... A Traffic Management Center in Woodbridge already serves as the headquarters for regional traffic information for the Turnpike, Parkway, state Department of Transportation and two divisions of the State Police... The traffic forecast would build on data collected at the center, possibly providing -- like a weather forecast -- color-coded models based on congestion levels. Green roadways would mean a delay of five minutes. Green with yellow would mean 10 minutes. Yellow with a lot of red would mean 15 minutes... (Photo from t2.gstatic: A NJ's traffic jam)

Brown Deer,WIS,USA -The USA TODAY, by Sherry P. Shephard -9 Oct 2010: -- Growing numbers of cities and towns are turning to solar-powered road warning and school safety signs to inform the public and save money and energy... In the past year, cities including Baton Rouge, Branson and Kansas City, Mo., and Lyndhurst, Wayne and Ringwood, N.J., have adopted the technology, officials in those municipalities say... Rick Bergholz, owner of TAPCO, a Wisconsin-based company that manufactures and sells the environmentally friendly traffic controls, says solar-powered light "sales have been exploding" ... "They've been around since their inception 10 years ago, but it took years to perfect the product and to get approval," Bergholz says. TAPCO's website lists Fort Worth, Tucson and Richfield Township in Ohio among other solar signal clients ...
