The City of Irvine, incorporated in 1971, is, according to their website, "...one of the United States' largest planned urban communities and encompasses more than 65 square miles." Part of Orange County in Southern California, Irvine is populated by more than 200,000 people making between 10,000 and 70,000 average daily travel trips.
One of the primary ways the city is keeping its citizens moving is through the use of traffic surveillance cameras and advanced traffic controllers deployed at its 300+ signalized intersections; Irvine's plan is to accommodate up to 500 intersections before the City's final development plan is built-out.
