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.

    Telematics Technology's Peter Billington describes the effort to give English local authorities and police forces a UTMC ANPR open communication protocol. The story of the impact of communication protocols on the development and utilisation of intelligent equipment is a familiar one both inside and outside the ITS industry. At the outset, a company pioneering its latest technology invariably develops a proprietary protocol. This enables the company's products to talk to the customer systems which need to a

    Signing the order to equip a new control room just 45 days before the city hosts a major sporting event is challenging - but some deadlines just cannot be moved. There is nothing like a deadline to concentrate minds and effort as Mitsubishi and the Brazilian city of Belo Horizonte discovered in the run-up to the 2014 World Cup. Although municipal authorities had been considering a new command centre for years, it was the hosting of the World Cup last summer that provided the final impetus.

    A common assumption, even amongst informed observers, is that there’s but a handful of urban charging schemes in operation around the world and scant prospect of that changing any time soon. Larger city-sized schemes such as Singapore, London and Stockholm come readily to mind but if we take a wider view and also consider urban access control and Low Emission Zones (LEZs) then the picture changes rather radically. There is a notable concentration of such schemes in Europe but worldwide the number is comfort

    Canadian researchers Olivier Quirion-Blais, Martin Trépanier and André Langevin have developed an algorithm to determine the most efficient routes for snow ploughs and gritters. Snow plough routing has always been something of a ‘black art’: to direct a fleet of show plough to clear priority roads without having the same road cleared several times while others are left untreated. Increasingly, GPS is being used to track the routes the clearing vehicles have taken but until now it has not been possible to ta
