TfGM makes progress on traffic management software

Transport for Greater Manchester (TfGM) has completed a trial to demonstrate how future mobility systems can support traffic management at a busy intersection.

Carried out as part of TfGM’s Synergy project with its partner Yunex Traffic (formerly Siemens Mobility’s Intelligent Traffic Systems), it integrated the V2X (vehicle to Everything) infrastructure, the communication of road signs via IVI (in-vehicle information) and the use of the Signal Phase and Timing (SPaT) software module and the company’s road unit (RSU).

This provided vehicles with Green Light Optimized Speed ​​Advisory (GLOSA) information, in line with TfGM’s goal of showing how such systems can support a safe and efficient road network.

The project focused on the A555 Manchester Airport Relief Road / Styal Road intersection in the south of the city, the largest and most complex intersection to which SPaT has been applied so far.

GLOSA and IVI messages were sent from the RSU installed on the Yunex traffic lights at the intersection, then displayed on the on-board unit of the test vehicle provided by NeoGLS.

This alerts the driver to the current state of a traffic light, the on-board system interpreting the SPaT message to advise him to adjust his speed to reach the intersection when the green light is on.

Ambitious project

Wilke Reints, UK Managing Director of Intelligent Traffic Systems at Siemens Mobility, said: “Considering the scale and complexity of the junction, this was certainly a difficult project, but with great collaboration between project team and a determination to make it work, the redesigned SPAT software has proven to be a real success.

“The test results were extremely encouraging and demonstrated the benefits that connected mobility solutions can bring to both traffic managers and road users, both helping to improve traffic flow at busy intersections,” and thus considerably reduce congestion and improve air quality.

Project Synergy was established in 2019 to test autonomous vehicles on roads in the Greater Manchester area. Specifically, it aims to test self-driving cars on a route from Stockport station to Manchester Airport and the use of self-contained pods in an airside environment at Manchester Airport.
