Hydro unveils rotating mast arm for traffic signals

Hydro is launching a rotating mast arm which it says will improve safety for operators responsible for maintaining traffic signals on multi-lane carriageways. Operators can control the rotating mechanism by using an internal winch located in a separate door compartment at ground level. The aluminium solution can either be installed in the ground or via the retention socket with anti-rotation design. Local technical support is available in the UK.

    October 26, 2017
    A new generation of video compression can lower transmission costs of data and make streaming from mobile and body-worn cameras a reality, as Colin Sowman discovers. Bandwidth limitations have long been the bottleneck restricting the expanded use of video streaming for ITS, monitoring and surveillance purposes. Recent years have seen this countered to some degree by the introduction of ‘edge processing’ whereby ANPR, incident detection and other image processing is moved into (or close to) the camera, so
