Many municipalities across the country coordinate traffic signal cycle lengths and background cycles along arterials to help achieve smooth travel progression. A cycle length can be defined as the green, yellow, and all-red times combined for each approach. Traffic signal progression prevents unnecessary delays for motorists. Similar cycle lengths along an arterial help achieve smooth progression. The Phoenix Area, as with many metropolitan areas, is made up of several separate jurisdictions. If all trips were made within the same jurisdiction and no boundaries were ever crossed, traffic signals could be coordinated within those respective boundaries and efficient progression achieved. However, this is never actually the case. Early on, the jurisdictions located in the East Valley of Phoenix operated their own traffic signal systems with some interjurisdictional coordination.
