542 Global Traffic Technologies (GTT) has been issued a US patent for its Opticom multimode phase selector technology, which allows traffic signal priority control systems to work with both legacy infrared and modern GPS-enabled communication technologies.

The multimode phase selector is a component of transit signal priority and emergency vehicle priority systems, enabling transport agencies to leverage existing technology when expanding their traffic signal priority systems, so existing IR-based systems can integrate with newer GPS-based systems.

Multimode capabilities allow authorities to cooperate more easily, in that emergency and public transit vehicles can move from areas with one technology to another without hindering their signal priority requests. In addition, multimode technology enables cities and agencies to put themselves on a migration path to newer technology.
