What if Highways Went Smart?

Highways are a classic example of a dumb technology. They just sit there and do one thing — assist in transportation. That has been good enough for many decades. But it may not be good enough for long.

Here are a few things highways may start doing

  • providing electricity via solar energy
  • connecting to cars to advise on safety conditions
  • help with directions and traffic

Just a few ideas — these and a lot more are being developed. CityLab has more.
