Siemens launches junction software to mitigate congestion


Siemens has introduced new adaptive traffic control software in the USA that allows controllers located at junctions to share information with one another on traffic and pedestrian conditions. This SEPAC ‘Peer-to-Peer’ software enables the on street network of controllers to adaptively respond to changing conditions in real time.

For example a controller could transmit information about a particularly large number of vehicles to other nearby controllers, which would in turn allow extra green time for the group to move through multiple intersections. The aim is to make traffic more efficient for operators and the travelling public.

“The new Siemens traffic control software includes an innovative approach for on street, adaptive solutions by leveraging peer to peer technology that will make intersections work even harder for drivers and help bring our traffic infrastructure into the 21st century,” said Siemens Intelligent Traffic Systems CEO Marcus Welz.

The technology has been proven in the city of Abilene, Texas, which is using it to improve traffic flow along a heavily travelled corridor.

“The City of Abilene has two state highways meeting at two intersections about 750 feet apart and has elevated railroads passing between them,” said traffic engineer for the city James Rogge. “This was a big problem when time clocks got out of step, making the traffic flow between the intersections was very inefficient.

“Since the implementation of Siemens SEPAC ‘Peer to Peer’ functionality, the city has seen significant improvements in traffic flow through this once congested area in Abilene.”
