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. Agencies can leverage existing technology when expanding their traffic signal priority systems, so existing IR-based s

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.

    Advances in vision technology are enhancing traffic surveillance and enforcement applications. Variable lighting conditions have long been a stumbling block for vision technology applications in the transport sector. With applications such as ANPR, the read-rate may vary between daylight and night and can be adversely affected by glare and low sun. Madrid, Spain-based Lector Vision had these considerations in mind when designing its Traffic Eye ANPR system, which combines off-the-shelf and custom hardware

Periodically, given the march of technology, it is worth pausing and taking stock of where we have got to and where we go next. Such reflections are necessary if we are to take full advantage of what we have at our disposal and, potentially, avoid decisions which push us down technological culs de sac.
