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.

    Debating the future of in-vehicle systems
    Industry experts talk to Jason Barnes about the legislative situation of current and future in-vehicle systems. Articles about technology development can have a tendency to reference Moore’s Law with almost indecent regularity and haste but the fact remains that despite predictions of slow-down or plateauing, the pace remains unrelenting. That juxtaposes with a common tendency within the ITS industry: to concentrate on the technology and assume that much else – legislation, business cases and so on – will m

    Siemens demonstrates new connected vehicle technology including iPhone app for traffic signal priority
    Can an iPhone change a traffic signal? All you need is the new Siemens app. New connected vehicle technology from Siemens Mobility and Logistics allows traffic signals to be controlled by vehicle arrival and priority rather than timing plans. Signal changes can even be triggered by an iPhone app combined with GPS, as Siemens demonstrates at ITS America.
