Transport for London (TfL) has deployed a new traffic signal system to upgrade its road network management.

Working with Yunex Traffic, it has transferred its ageing traffic signal system to the cloud based Real Time Optimiser (RTO) system.

It said this is part of a move towards an intelligent adaptive traffic signal system that enables optimisation of ‘green time’ for street users including pedestrians, bicycles, buses and car, and that it is expected to improve journey times, traffic flows and responses to incidents.

Almost 4,000 junctions, 1,500 pedestrian crossings and more than 16,000 traffic detectors across Greater London were migrated to a new system over a two-week period.

The RTO system will cover around 6,400 automated traffic signal junctions and pedestrian crossings, one of Europe’s largest traffic signal networks.

Data potential

It will also provide TfL with the platform to support the introduction of FUSION, a new intelligent adaptive control optimiser, which can replace the existing SCOOT system that has been operating across London for more than 30 years. TfL said will be pivotal in improving air quality across the city, reducing congestion and helping traffic flow by using a wide range of modern data sources techniques.

Its director of network management and resilience, Carl Eddleston, said: “London’s road network plays a vital role in enabling millions of journeys each day and we’re determined to ensure that people can walk, cycle, take the bus and drive as safely and efficiently as possible.

“This world leading new traffic management system will be a game changer for us in London. It will use new data sources to better manage our road network, tackle congestion, reduce delay for people choosing healthier travel options and improve air quality.”
