GTT - Emergency-Vehicle Preemption and Transit-Signal Priority Systems

Global Traffic Technologies (GTT) is dedicated to providing communities with the best emergency-vehicle preemption, transit-signal priority, and traffic-management systems.

Opticom™ systems are installed in over 1,500 communities and 60,000 intersections globally. Look to GTT for the reliability and performance you can count on to reduce greenhouse gas emissions, minimize traffic congestion, and increase safety while maximizing resource efficiency and investment.

GTT provides solutions with measurable results that help you build a more livable community.

Emergency-vehicle preemption (EVP) systems

EVP systems are designed to give emergency-response vehicles a green light on their approach to a signalized intersection and clear the traffic queue in highly congested intersections, therefore allowing for faster, safer response to emergency incidents.

Benefits of our EVP systems include:

• Reduced incident-response time for law enforcement, fire and EMS personnel
• Improved safety of emergency personnel through crash reduction
• Increased efficiency of emergency resources and investment

Transit-signal priority (TSP)

TSP is a safe, secure transit strategy that provides preferential treatment of in-service transit vehicles when traveling through traffic-signal-controlled intersections.  TSP is also a recommended intelligent transportation system (ITS) technology for bus rapid transit (BRT) systems. Benefits include:

• Lower and more consistent travel times
• Improved schedule reliability and adherence
• Lower fuel consumption and emissions
• Increased air quality and environmental sustainability

EVP system management

Integrate Opticom™ Central Management Software into the traffic management operations center to efficiently control, monitor, manage, maintain and secure your traffic signal preemption system from your desktop. With high-speed communications to the intersection becoming pervasive, management of the preemption system can now be performed from a central location, minimizing the need for local intersection management.

Infrared and GPS EVP and TSP systems

The Opticom™ Infrared System and Opticom™ GPS System are proven technology solutions for emergency vehicle preemption and transit signal priority. The Opticom™ Infrared System uses coded infrared transmitters mounted on a vehicle to communicate securely with the intersection traffic controller. The Opticom™ GPS System uses GPS technology and highly secure radio communication to deliver safe, efficient results. 

Traffic sensing system

The Canoga™ traffic sensing system is the ideal application for traffic operations engineers who need year-round consistency and accuracy relative to real-time individual vehicle speed and length data (mean traffic-flow information) for every lane to manage daily traffic. It offers unparalleled benefits when compared to other vehicle detection systems.
