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.

    Though still controversial, ramp metering, which has been around for nearly 50 years, continues to deliver substantial benefits, and generally for relatively small cost. Kansas City is a case in point. In March 2010, Kansas City Scout, a partnership between the Missouri and Kansas Departments of Transportation to provide ITS for the greater Kansas City Area, activated the first ramp metering system in the region. The project is located on an 8.85km (5.5 mile) section of Interstate 435 from Metcalf Avenue to

    The latest research by the US Insurance Institute for Highway Safety (IIHS) found that red light running rates declined at Arlington, Virginia, intersections equipped with cameras. The decreases were particularly large for the most dangerous violations, those happening 1.5 seconds or longer after the light turned red. "This study provides fresh evidence that automated enforcement can get drivers to modify their behaviour," says Anne McCartt, senior vice president for research at IIHS and the study's lead au
