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.

So what can Japan, and indeed Brazil, learn from the traffic management for London 2012 - Geoff Hadwick finds out. It was a key moment when Olympic boss Jacques Rogge signed off London 2012, calling the Games “happy and glorious.” Scarred by the logistical disaster of Atlanta 1996 and the last-minute building panic for Athens 2008, Rogge clearly thought London 2012 was an object lesson in how to plan and

    An Argentinian authority is using night-time cameras to fight criminal activity aboard buses. Instances of crimes and violence (especially on city buses or at bus stations) have motivated the city of Rosario in Argentina to improve safety and security on the Urban Transportation System – or the TUP as it is known locally. As posting a police officer on each bus would be cost-prohibitive and uncomfortable for some passengers, security cameras are being fitted to each TUP bus. This solution entailed instal

A family with a small boy – about nine years old – boarded the same train. They were American and we st
