TWENTY-FIRST-CENTURY TRAFFIC TECH

摘要

Imagine this: you set out to drive across town to meet a friend. Before you start, you pull up a map of the route on your car's navigator. Anticipating the traffic expected during the next twenty minutes and the approximate duration of the drive, your navigator suggests a route that should be the least congested. You click to accept the route and follow it to your destination without incident.rnOnce you arrive, LED signs on the street point you toward blocks with available parking and alert you to the nearest recharging station. Wasting no time circling the area, you slip into a free spot, plug your car into the post, lock up, and use your phone to pay for two hours of parking and charging.
