EMTRAC Transit Signal Priority

For over 25 years, the EMTRAC system has been used throughout North America to help first-response and transit vehicles get to their destination both quickly and safely.

EMTRAC staff members have extensive experience in traffic and transit management. They've worked in the industry for many years, and they've helped implement the system in both large and small municipalities.

The EMTRAC system is the most advanced priority management system available—but it's also the easiest system to install and maintain. The most important endorsement of the EMTRAC system is found in the positive comments from agencies using  the system. We encourage you to contact EMTRAC customers to hear these comments for yourself.
