Traffic Technology Services and Siemens partnership will advance V2I deployment

Traffic Technology Services Inc. (TTS) and Siemens USA have finalized an agreement to expand TTS’s partner network for supporting connected and autonomous vehicle (CAV) operations near signalized intersections using vehicle-to-infrastructure (V2I) technology.

Starting this month, selected deployments of Siemens TACTICS ATMS (advanced traffic management system) platform, will supply traffic signal data to TTS cloud-based services to support connected vehicle applications that are intended to improve safety, mobility, and the environment.

The joint service will be implemented initially in: the City of Aurora in the Denver metropolitan area (Colorado); the City of Fargo (North Dakota); the City of Fremont in the greater San Francisco area (California); and East Whiteland and Upper Merion Townships in the Philadelphia area (Pennsylvania).

Information from the TACTICS platform will be sent to TTS’s Personal Signal Assistant, a data message containing two components: a message containing information about the traffic light’s Signal Phasing and Timing (SPaT) state; and a MAP message with information about the geometry or topology of the intersection. The SPaT message includes both the current signal state and a prediction of how long it will remain in a green, yellow or red signal state. TTS uses traffic signal data, both in real time and aggregated over time, to provide a prediction of the signal state.

Siemens TACTICS platform is harnessing real-time traffic data that is used in the TTS cloud-based Personal Signal Assistant information service to provide a predicted and current intersection signal status. Every second at every intersection, TTS predicts the signal operations using its patented technology, and these predictions and intersection layouts are then provided as data used for CAV applications.

Siemens traffic data and analytics software enables an effective and secure solution from data capturing to actionable, real-time and measured information processing. Through the new partnership, automotive, truck and transit OEMs, in addition to aftermarket device manufacturers and navigation service providers, will have greater access to signalized intersection data for connected vehicle applications. The Personal Signal Assistant service supports various connected vehicle applications, most notably the Audi Connect Traffic Light Information feature.

“With hundreds of TACTICS systems controlling thousands of intersections across the USA, we are the country’s leading intelligent traffic providers and pioneer in connected vehicle technology, and we are excited to bring this expertise to our new partnership with TTS,” said Marcus Welz, CEO of Siemens Intelligent Traffic Systems in North America.

“This partnership directly aligns with the long-term vision of the USDOT’s vehicle-to-infrastructure initiative and will advance the industry’s efforts toward a connected vehicle future.”
