In the dynamic realm of urban transit, optimizing efficiency and reliability is paramount. Enter Cellular Signal Priority, a cutting-edge technology revolutionizing the way transit vehicles navigate city streets. Leading the charge in this innovation is The EMTRAC Priority Management System, leveraging precise navigation technology and secure RF communication to detect equipped transit, emergency, and municipal vehicles, thereby facilitating priority or preemption requests to intersection signal-control equipment. Understanding Cellular Signal Priority: Cellular Signal Priority operates on a similar principle to its RF-based counterpart but utilizes cellular networks for communication instead. Equipped transit vehicles transmit their location and status data via cellular signals to centralized servers. These servers then relay this information to intersection signal-control equipment, prompting adjustments to traffic signals in real-time to prioritize the passage of transit vehicles.
