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.

    School authorities in the US are turning to automated school bus stop arm enforcement to curb an astonishing number of violations. It is estimated that every year nearly 17,000 American children are sent to emergency rooms as a result of school bus related crashes. And when surveyed, 99% of school bus drivers reported that the most dangerous behaviour they encounter is drivers passing a school bus with its stop sign arm extended. Every day these drivers who violate the extended stop arm signs put at risk

    Jason Barnes considers the social and ethical ramifications of using in-vehicle safety technologies to fulfil enforcement functions. Although policy documents often imply close correlation between enforcement, compliance and safety – in part, as a counter to accusations that enforcement is rather more concerned with revenue generation – there is a noticeable reluctance among policy makers and auto manufacturers to exploit in-vehicle safety systems for enforcement applications.

    Q-Free’s Andrew Lees looks at regional characteristics and technology trends in the global Weigh-In-Motion market. The principles of Weigh-In-Motion (WIM) are well established. Data derived from vehicles passing over in-ground sensors can be interpreted for vehicle classification (axle counts and spacing) and positive identification (especially when linked to image capture) applications as well as to derive individual axle and gross vehicle weight (GVW).
