Patent for GTT multimode phase selector

US-based Global Traffic Technologies 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 an important component for transit signal priority (TSP) and emergency vehicle priority (EVP) systems.

US-based 542 Global Traffic Technologies 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 an important component for transit signal priority (TSP) and emergency vehicle priority (EVP) systems. Agencies can 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 in an easier fashion, in that Emergency and public transit vehicles can move from areas with one technology to another without hindering their signal priority requests. Finally, multimode technology enables cities and agencies to put themselves on a migration path to newer technology, without having to do everything at once.

    Jason Barnes considers the social and ethical ramifications of using in-vehicle safety technologies to fulfil enforcement functions. Although policy documents often imply close correlation between enforcement, compliance and safety – in part, as a counter to accusations that enforcement is rather more concerned with revenue generation – there is a noticeable reluctance among policy makers and auto manufacturers to exploit in-vehicle safety systems for enforcement applications. From a technical perspective t

    A new traffic management solution is attempting to bridge the gap in information available on freeways and arterial roadways. Andrew Bardin Williams reports. Agencies responsible for national networks of roads around the world have the ability to measure, analyse and disseminate accurate travel information to drivers. Millions of dollars go into data collection infrastructure to collect traffic congestion and travel time information on major freeways or highways. For example, a driver on the I-210 in the Lo

As ITS advisor and road finance director for the International Road Federation (IRF) in Geneva, Caroline Visser is well placed to evaluate quantifying the benefits of ITS implementation – a topic about which there is little agreement and even less consistency. She is pressing to get some consistency in the evaluation of ITS deployments through the use of
