542 Global Traffic Technologies (GTT) 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 a component of transit signal priority and emergency vehicle priority systems, enabling transport agencies to 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 more easily, in that emergency and public transit vehicles can move from areas with one technology to another without hindering their signal priority requests. In addition, multimode technology enables cities and agencies to put themselves on a migration path to newer technology.

    Next year sees the start of the first real-life electrified road system for transporting freight. Worldwide freight transportation is predicted to double by 2050 but despite expansion of global rail infrastructure only one third of this additional freight transport can be handled by trains. This means that the largest proportion of freight transport will continue to be by road and as a result, experts expect global CO2 emissions from road freight traffic to more than double by 2050.

    Jon Masters looks at a smartphone app which could be the ‘disruptive technology’ that eases the way to interoperability in tolling systems. Consumer demand may soon drive the biggest step change yet in tolling. In the United States a new start-up company, Geotoll, has launched a smartphone app for electronic toll payment. It is not beyond possibility that rapid growth of the market for smartphones will continue – an estimated 50% of US citizens and 80% of Europeans now have one – and that the Geotoll brand
