About the Vehicle Control Head
The EMTRAC system is used by first-response and transit agencies to request signal priority, track vehicle locations, improve signal coordination, and increase safety. This is done by combining precise GPS technology with secure FHSS radio communication.
The control head enables vehicle operators to monitor system activity and performance in real time. In addition to other features, drivers may be alerted when priorty requests have timed out and when there is immediate potential for collision.
EMTRAC-equipped vehicles carry a compact, yet rugged, Vehicle Computer Unit (VCU) that is connected to a dual GPS/UHF antenna. The onboard VCU serves as the control center of the vehicle’s EMTRAC system, while the connected control head displays system activity. The Program-Capable model enables drivers to adjust system settings as needed.
Control Head Benefits
- Safety: Reduce collisions between equipped vehicles responding to the same emergency or on the same route by proactively alerting drivers of potential hazards.
- Efficiency: The Program-Capable model is equipped with a USB port, enabling agency personnel to load only intersections and detection zones for specific routes. It is also equipped with an Ethernet port, which may be used to download data or upload firmware updates.
- Reliability: The touchscreen models enable drivers to reset timed-out requests to help clear intersections in even gridlock conditions.
- Flexibility: The EMTRAC system may be installed on any vehicle type (first-response, buses, LRVs, snow plows, etc.), and control heads may be installed on only select vehicles.
