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.

A 2011 study by IBM of 20 cities around the world found that nearly six out of ten drivers had abandoned their search for a parking space at least once; while motorists generally spent on average 20 minutes looking for a sought-after spot.

    Based on experience gained from its truck detection systems, Swiss company Tinynode has launched a wireless car parking detector, which can be used for off-street parking and is designed to be integrated with existing parking systems. Two models are available, the A4 which is screwed or glued on to the road surface, and the B4, which is embedded into the road surface. Both are easily installed and have a life of around ten years; batteries are easily replaced without disturbing the road surface.
