Cullman Alabama Preemption and Priority Deployment

Cullman, AL is a city of approximately 20 square miles and more than 15,000 residents. Popular for its strong school system, recreational opportunities and low cost of living, the city has been named as one of the best places to live in Alabama.

In 2016, officials decided to provide traffic signal preemption to the emergency vehicles across the city. Traffic signal preemption requests are critical to ensuring that emergency vehicles are able to arrive on scene as fast as possible. These systems ensure that the traffic signals are prepared for the emergency vehicle and ensure safe passage through the intersection. In addition to the preemption capabilities, the city wanted the ability to monitor the performance of their traffic signals and install a system that required little to no maintenance.

After reviewing a number of solutions, Cullman officials selected the Glance Preemption & Priority System from Applied Information. The Glance Preemption & Priority System utilizes web and cloud based computing to seamlessly combine cellular, radio transmission and GPS technology into one solution.
