Stateline: States roll out plans for 'smarter' roads

From Stateline:

Not all the highway improvement projects states plan to pay for with federal stimulus money involve widening roads, fixing bridges or repaving highways. Nearly half the states plan to use some of their new funds to pay for high-tech gadgets that will reduce congestion, help the environment and create jobs quickly.  At least 22 states have told the federal government they want to make their roads “smarter” by installing traffic cameras, creating express toll lanes, improving traffic signals and alerting drivers about accidents or delays ahead, according to the National Conference of State Legislatures.
