PHOENIX ‒ It may not be surprising to hear that coordinating the timing of city traffic signals and those at two busy Interstate 17 interchanges will save drivers time.
But the Arizona Department of Transportation and its partners, the city of Phoenix and Maricopa Association of Governments, have taken it a step further by adding up the time saved and its dollar value for a project involving Camelback and Indian School roads.
The answer: Motorists are expected to save 350,000 hours of travel time, worth $6.2 million, per year.
