Using Mobile Phones to Find Traffic Jams
Scott Barlow sent me a pointer to this story about using cell phone triangulation data to determine traffic congestion. The Bangalore Traffic Information System is offline at the moment—Slashdot effect, I’m sure.
Of course, you can tell more than how congested the roadways are. You can also determine commuting patterns—in aggregate—over time. When they redid I-15 through Salt Lake before the Olympics, all kinds of sensors were embedded in the roads to give UDOT this kind of information. This is a novel use of data that’s already there to accomplish the same thing without the additional infrastructure.

So is Utah using the embedded sensors to track cell phone data yet? If we have the infrastructure, are we at the point here where that data would be beneficial? I also wonder if the traffic cameras have software that can handle some of that data.
