Plus+ 3rd generation traffic control system
The latest development in traffic control uses distributed intelligence to increase intersection uptime and reduce on-street installation and maintenance time
With financial and people limitations and increasing pressure on our congested road infrastructure it's no surprise to know that on-street engineering time is a major challenge for those responsible for traffic management. The new ST950 Plus+ system from Siemens 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, as well as saving valuable resources. Plus+ uses dedicated failsafe controllers, signal heads, and pedestrian indicators as well as new smartloop modules ensuring that the overall system is tolerant of individual component and cable damage, resulting in higher intersection availability and reduced disruption to the travelling public.
Addressing the safety and availability challenges when delivering distributed Traffic Control systems
We will be exploring the safety and system challenges which have been successfully addressed in the Siemens Plus+ system, to ensure that a distributed Traffic Control system delivers both savings in on-street implementation as well as maximum on-going availability under a wide range of possible fault conditions.
- Fewer, lighter cables are needed
- Cabling approach makes use of low-level access poles much easier
- Cabling approach makes pre-assembly of poles and heads more efficient
All of these factors mean that there is potentially a significant reduction in on-street working time, meaning a quicker and safer installation.
