Siemens to deliver first Plus+ on-street trials this June


Since its preview at Traffex two years ago, Siemens Mobility’s Plus+ solution has taken significant strides towards becoming what could be the most advanced and cost-effective solution for resilient traffic intersections.

The Siemens Mobility development team has been working for over three years to bring this new technology to completion and the first on-street trials are expected to take place in Poole at the end of June 2019.

The groundbreaking Plus+ system is designed to deliver on-street resilience and reliability and save time and effort at installation.

This means welcome cost and efficiency savings for major new schemes and refurbishment initiatives.


Plus+ uses distributed intelligence with simple power and data cabling to increase intersection availability and reduce overall installation and maintenance costs.

By drastically reducing the raw materials, cabling and people-power required compared with traditional systems, it supports minimised disruption and optimised traffic flow on the UK’s increasingly congested road network.

With digitalisation, Siemens Mobility enables mobility operators worldwide to make their infrastructure and networks intelligent and ultimately, to deliver an enhanced experience for road users and city dwellers.

Plus+ has been designed with dedicated failsafe controllers, signal heads, and pedestrian indicators as well as new smart loop modules to make sure that the overall system is tolerant of individual component and cable damage. This results in higher intersection availability and most significantly, reduced disruption to road users.

The modular Plus+ system has been developed to incorporate Siemens Mobility’s proven traffic control products, including its ST950 controller, Helios signal heads and pedestrian indicators and also remains fully compatible with other key traffic control solutions such as above ground detectors, standard loop detectors and WiMag, if required.

As well as the advantages coming from the quicker and safer installation and the robust nature of the design, the Plus+ system also includes enhanced ‘self-checking’ and diagnostics which provides additional protection against false signals being shown on-street due to error or deliberate acts.

Martin Baker, road safety and network manager at Bournemouth, Christchurch and Poole Council, said: ‘We are very happy to support Siemens Mobility in trialling this latest exciting technology.

‘We see the Plus+ system as a valuable addition to the portfolio of solutions we can use, helping us to deliver new schemes more efficiently and with less disruption to the travelling public.’
