Wall Street Journal: States Wire Up Roads as Cars Get Smarter - Planners say "˜smart roads' will unlock benefits from self-driving cars, curb accidents, but costs are high

QuoteOn a crowded interstate outside Washington, D.C., large digital signs over four westbound lanes flashed messages lowering the speed limit by 10, then 20 miles an hour.

QuoteDrivers slowed just as a fast-moving thunderstorm unleashed sheets of rain that drenched the road and reduced visibility to a few dozen yards. There was no abrupt braking, no swerving and none of the fender-benders that can tie up traffic for miles.

QuoteThe signs, installed last year, are a first step toward what highway planners say is a future in which self-driving cars will travel on technology-aided roads lined with fiber optics, cameras and connected signaling devices that will help vehicles move as quickly as possible–and more safely.
