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.

    The continued expansion of IP camera networks increases the availability of useful information. At the same time, the opportunity exists to increase inter-agency collaboration. This makes information management all the more necessary in the control room environment. But the transportation sector could do a lot to help itself by gaining a better idea up front of what and how it wants to do things, says Electrosonic's Karl Johnson.

    David Crawford looks at technologies for better emergency medical service delivery. Emergency medical services (EMS) play key roles in transporting, or bringing treatment to, patients who become ill through medical emergencies or are injured in road traffic accidents (RTAs). But awareness has been rising steadily, in the US and elsewhere, of the extent to which EMS can generate their own emergencies. The most common cause is vehicles causing or becoming involved in RTAs, as a result of driving fast under pr

    Paul Laurenza of Dykema Gossett PLLC discusses the paths which lawmakers may go down on the route to making in-vehicle systems and cooperative infrastructures a reality. The question of whether or not to mandate in-vehicle systems for safety and other applications is a vexed one. There is a presumption on some parts that going down the road of forcing systems' fitment is somehow too domineering or restricting. Others would argue that it is the only realistic way of ensuring that systems achieve widespread d

    For many, Ethernet- and IP-based networks are the cast-iron solution to ITS's communications needs. However, there remain issues from manufacturer to manufacturer with interpretation of what are supposed to be common standards The 'promise' of Ethernet was that different devices such as IP video cameras and traffic signals could be easily integrated into communications networks, simplifying the process of transporting data over copper, fibre or wirelessly. However, although Ethernet devices have come to pre
