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.
