Would Sioux Falls Benefit From New Traffic Lights?

There are plenty of dumb drivers -- but would traffic flow be better with smart lights? High-tech traffic lights are being tested in Pittsburgh in the city's congested East Liberty section.

The technology was developed at Carnegie Mellon University.The lights are able to communicate to keep traffic moving. Researchers say a pilot program shows commute times through the area have been cut by 26 percent. Officials now want to expand the smart light test.

Sioux Falls might never be a test market for these high-tech traffic lights but lets just say, for a minute, you were the city engineer in charge of placement. What intersection would benefit the most from this new form of traffic technology?

There always seems to be one or two traffic signals (OK, maybe a dozen) on your commute that never seem to be green. Where are they?
