The EMTRAC System Utilizes Precise GNSS Technology and Secure Wireless Communication to Provide Reliable, Safe, and Efficient Signal Priority The EMTRAC system, a pioneer in intelligent C-V2X Signal Priority, has been a leader in the field for over 30 years. Leveraging advanced GNSS technology and secure wireless communication, the EMTRAC system ensures that signal priority is reliable, safe, and efficient. EMTRAC-equipped vehicles continuously monitor real-time conditions along their routes to determine if signal priority is needed to maintain their schedules. When a priority request is warranted, the vehicle sends a signal-priority request to the relevant intersection, seamlessly integrating with existing traffic systems. Several factors influence the granting of signal priority requests. These include the time of day, passenger load, the extent of the delay, and the time elapsed since the last request. By considering these variables, the EMTRAC system ensures that signal priority is granted judiciously, balancing the needs of public transit with overall traffic flow. This automatic process eliminates the need for driver intervention, enhancing the system's efficiency and reliability.
