Abstract:To achieve the full integration of varied traffic management, emergency services and transit systems in the sprawling Valley of the Sun metropolitan area, no small amount of coordination is required. In the interest of smoothing vehicle traffic that crosses municipal boundaries, AZTech promotes the coordination of traffic signal systems between neighboring cities. The Town of Paradise Valley, the smallest AZTech municipal partner in terms of population, was not equipped with a central control for its 12 recently modernized traffic signals. Its neighbors, Scottsdale and Phoenix, each operate a computerized, central-control traffic system. To accurately coordinate signals between these disparate systems would be next to impossible. On the other hand, building a central-control system for Paradise Valley would be an expensive undertaking. To attain the desired coordination between its partners, AZTech was charged with developing a cost-effective solution for making the signal system of Paradise Valley compatible with its neighbors' state-of-the-art systems.
