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.

Intersection crashes continue to represent a worryingly large share of deaths and serious injuries across US highway networks. Statistics from the US Department of Transportation’s Federal Highway Administration show that an average of 21% of road traffic accident deaths occur at crossings. The National Highway Traffic Safety Administration (NHTSA) calculates that intersection crashes account for 48% of all injury-related i

    According to Ertico, the future of traffic management on urban and inter-urban networks will rely on direct communication and interaction between vehicles and the infrastructure, using new technologies called cooperative intelligent transport systems (C-ITS) that support real-time exchange of traffic data. This cooperation can enable a wide range of applications such as vehicle-sourced data collection, green light and speed advice, automated hazard detection, selective vehicle priority, dynamic city logisti
