GTT patents link legacy infrared and GPS-based priority systems

0

Global Traffic Technologies (GTT) has been issued with 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.

GTT’s Multimode phase selector is a crucial component for transit signal priority (TSP) and emergency vehicle priority (EVP) systems. Agencies can make use of existing technology when expanding their traffic signal priority systems, so existing infrared-based systems can integrate with newer GPS-based systems. Multimode capabilities allow authorities to cooperate in an easier fashion, in that emergency and public transit vehicles can move from areas and jurisdictions with one technology to another, without hindering their signal priority requests. Multimode technology also enables cities and agencies to put themselves on a migration path to newer technology, without having to do everything at once.

GTT is the holder of more than 100 domestic and international patents. The multimode phase selector patent, ‘Prioritization of traffic signal preemption requests received from multiple sources over different communication mediums,’ is US patent number US9478131 B2. Opticom multimode systems enable cities to deploy TSP and EVP enhancements with out-of-the-box affordability and seamless scalability. The multimode system can be combined with GTT’s Opticom Central Management Software (CMS) to give traffic engineers data-driven information in real-time so that they can make more informed decisions that improve emergency response service levels, reduce maintenance costs and enhance overall traffic safety. The combined Opticom systems help emergency, transit and traffic personnel increase safety, minimize traffic congestion and reduce greenhouse gas emissions, while maximizing resource efficiency and performance.

“The establishment of this new intellectual property (IP) is further evidence of the company’s commitment to technological leadership and customer focus,” said GTT’s president, Doug Roberts. “We aim to be first to market with products that make a real difference to our customers.”
