The Wallstreet Journal released an article detailing how new "smart" infrastructure can reduce congestion and help America build for the future.

The article discusses smart transportation and cites how CalTrans has been reviewing car travel speeds in the Bay Area to predict when traffic jams will occur, before they occur. Regardless, there is a large demand for more data in order to create the necessary models that will estimate arrival times. Singapore currently uses IBM technology to predict congestion blocks up to 45 minutes before they happen.
It also discusses the use of smart bridges, which can have sensors detect stress points in a bridge during high traffic times. This will allow for better maintence, and reduce incidents like the Minnesota bridge collapse.
The article also discusses the smart grid and smarter water systems.
A good article to read for anyone working in the city.
