Fewer cables for Siemens ST950 Plus+ traffic controller

The latest controller and signals system from Siemens, the ST950 Plus+, uses fewer cables and a smaller controller cabinet than other systems. The aim of the Plus+ solution is to offer significant reductions in on-street installation and maintenance time, improved safety and reduce deployment costs compared to conventional methods. In short, it’s easier and faster to install and later maintain, explained Keith Manston, head of product management for Siemens.

The aim of the Plus+ solution is to offer significant reductions in on-street installation and maintenance time, improved safety and reduce deployment costs compared to conventional methods.

In short, it’s easier and faster to install and later maintain, explained Keith Manston, head of product management for Siemens.

Signals can be pre-assembled and the system uses low-level access poles, meaning installation engineers spend less time working on-street and so reduce risk to themselves and public disruption.

The new ST950 Plus+ system no longer uses many individual connections between signal heads and controllers. Instead it uses simple four core cables and intelligent communications to reduce the installation effort.Plus+ uses dedicated failsafe controllers, signal heads and pedestrian indicators. It also incorporates new smart-loop modules ensuring the system is tolerant of individual component and cable damage. The result is higher intersection availability and reduced disruption to the travelling public.

    The latest technology continues to improve the quality of concrete paving while contractors are also benefiting from more adaptable equipment - Mike Woof reports For many concrete paving applications, versatility is required rather than a high production rate. Leading paver manufacturers such as GOMACO, Power Curbers, Terex and Wirtgen all offer high mobility machines that can be adjusted to cope with an array of tasks. For a contractor, the advantage of these smaller pavers is that they can be configured q

    Raising awareness of safety in highway work zones is a global issue, and various initiatives highlight this as Patrick Smith reports. So seriously is work zone safety taken in the United States that each year since 1999 a special week has been set aside to highlight it. Each year in April, National Work Zone Awareness Week is held to bring national attention to motorist and worker safety and mobility issues in work zones.
