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.

Five thousand miles of tolled roads and bridges. Widespread implementation of electronic toll collection (ETC) systems. One dominant interoperable ETC service provider covering just over half the nation’s toll facilities. Numerous other ETC service providers offering alternative visions of interoperability.

  • EdgeVis removes bandwidth barriers to mobile streamed video
    October 26, 2017
    A new generation of video compression can lower transmission costs of data and make streaming from mobile and body-worn cameras a reality, as Colin Sowman discovers. Bandwidth limitations have long been the bottleneck restricting the expanded use of video streaming for ITS, monitoring and surveillance purposes. Recent years have seen this countered to some degree by the introduction of ‘edge processing’ whereby ANPR, incident detection and other image processing is moved into (or close to) the camera, so

    December 23, 2015
    For ITS to gain the recognition it deserves, Q-Free’s Knut Evensen argues that the sector must have a coherent message and avoid confusing the wider community with a bewildering array of terms and acronyms. Any industry or group of people will develop its own lexicon over time. The process is near-inevitable, as individuals’ knowledge bases increase and evolve, and terms for common wisdom are created and become truncated, or even slang. A danger, though, as a relatively small group looks to admit large numb
