Siemens delivers pedestrian countdown at traffic signals

Siemens’ new Pedestrian Countdown at Traffic Signals (PCaTS) informs pedestrians how long they have to cross the road after the green man signal has gone out, by providing a visible countdown of the time remaining before the appearance of the red man.

189 Siemens’ new Pedestrian Countdown at Traffic Signals (PCaTS) informs pedestrians how long they have to cross the road after the green man signal has gone out, by providing a visible countdown of the time remaining before the appearance of the red man.

The system is compatible with Siemens’ Helios Traffic c signals and can be specified with a new installation or retrofitted to existing sites (including Peek Elite signals).

It features highly visible double stroke LED digits and is enhanced by the use of a flat lens which is ‘black masked’ to minimise sun phantom reflections. The unit may also be fitted with a small hood to further enhance the sun phantom performance if required.

Once installed, the unit automatically detects the blackout period after two learning cycles of the signals. Timing synchronisation with the blackout period is achieved by direct connections to the red and green signal feeds via isolated input circuits designed to ensure there is no impact on controller lamp or safety monitoring.

These inputs also sense the dim/bright state of the signals to automatically dim the PCaTS unit.

    Construction work has started on Nottingham's expanding tram network to extend the service to the south and southwest of the city. The extension will more than double the size of Nottingham's tram network with 17.5 kilometres of new track and 28 new tram stops. As part of the project, Siemens will supply and install 33 new ST950 extra low voltage (ELV) junction controllers, eight signalised pedestrian crossings and 80 ELV tram signals. Junction controllers at a number of existing sites will also be upgra

    Two decades after the death of the inductive loops was predicted, Matt Zinn, technical services manager at Eberle Design says the technology still offers advantages. More than 20 years ago the emergence of video detection systems led many to foretell the end of inductive loops. In the intervening years advocates of radar, infrared and wireless detection technologies have also claimed that loops were on their way out. But in fact, by all calculations, the use of loops has actually increased and although
