Siemens introduces new software for ‘talking’ traffic intersections
In the field, a controller can transmit information about a large number of vehicles to a controller at the next traffic signal. This allows extra green time for the group of cars to move through multiple intersections, making traffic more efficient for operators and the traveling public.
Siemens expanded its industry-leading portfolio of adaptive traffic control software by introducing SEPAC “Peer-to-Peer,” a new traffic software that allows controllers located at intersections to share information with one another on traffic and pedestrian conditions. This “connected” capability allows the on-street network of controllers to adaptively respond to changing traffic conditions in real-time.
In the field, a controller can transmit information about a large number of vehicles to a controller at the next traffic signal. This allows extra green time for the group of cars to move through multiple intersections, making traffic more efficient for operators and the traveling public. Abilene, Texas is one city using the “Peer-to-Peer” technology to increase traffic flow along a heavily traveled corridor.

“The City of Abilene has two state highways meeting at two intersections about 750 feet apart and has elevated railroads passing between them. This was a big problem when time clocks got out of step, making the traffic flow between the intersections very inefficient,” said James Rogge, traffic engineer for the City of Abilene. “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. Commuters have even called the City expressing their contentment with and realization of improvement to traffic flow."
“Siemens is continuing to lead the industry in adaptive traffic signal control systems, developing a broad variety of technologies to reduce travel time and delays and ultimately solve congestion in cities of all sizes,” said Marcus Welz, CEO of Siemens Intelligent Traffic Systems. “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.”
The Peer-to-Peer feature gives operators a greater level of insight into traffic conditions and more accuracy in adapting traffic patterns to increase flow and ultimately reduce congestion. Also, the SEPAC software can be installed in existing traffic controllers and doesn’t require any additional equipment or IT infrastructure.
The OKC transit agency says sponsorship helps subsidize the Third Friday Free initiative while reducing barriers for first-time riders and boosting ridership across buses, streetcars, and river cruises.
The Scheduling and Supply Studio provides the world’s first fully integrated platform for optimizing vehicle and driver availability to rider demand, said company officials.
ABQ RIDE Forward is the first transit system overhaul in more than 25 years. This latest phase marks 15% completion of the 16-phase rollout, which will continue over the next several years.
Today’s riders—and the communities you serve—expect more from public transit. While ADA compliance is required, leading transit agencies know that true accessibility also means delivering dignity, efficiency, and a better rider experience. This whitepaper reveals why forward thinking agencies nationwide choose the Low Floor Frontrunner as their first choice for ADA compliant vehicles—setting a new standard with passenger first design, faster boarding, improved safety, and unmatched operational performance.
