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.

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.

    Additional functionality gives loops a continued lease of life
    Two decades after the death of the inductive loops was predicted, Matt Zinn, technical services manager at Eberle Design says the technology still offers advantages. More than 20 years ago the emergence of video detection systems led many to foretell the end of inductive loops. In the intervening years advocates of radar, infrared and wireless detection technologies have also claimed that loops were on their way out. But in fact, by all calculations, the use of loops has actually increased and although

    Israel aspires to ITS-led future
    Shay Soffer, Chief Scientist with the Israel National Road Safety Authority, talks to Jason Barnes about his country’s current ITS outlook and how he sees this developing in the future. Israel ranks alongside countries such as the US and France in the road safety stakes, with an average 7.1 deaths per billion kilometres driven. But at that point the similarities end, as the country’s overriding issue is pedestrian safety. This is driven by several factors, including being a relatively small country where pe
