Abstract:
The Virginia Dept. of Transportation has spent more than $30 million on the first 2 miles (3.2 km) of the planned 5.7 mile (9.2 km) Smart Road near Roanoke, Virginia. Eventually the road will connect Blacksburg, Virginia, to Interstate 81. But until it does, the first section of the road will serve as a world-class intelligent transportation system technology test bed. Controlled tests will be performed by the Virginia Tech Center for Transportation Research, which fitted the road with more than 12 pavement designs, 600 pavement sensors, 75 snowmaking towers for all-weather testing, and 60 different light towers. A 30,000 sq ft (2,787 m�) control center will gather data collected from the instrumented road via a fiber optic transmission line.
