City of Frisco Vehicle to Infrastructure Implementation (V2I)

April 25, 2017 by Dafne Valle

Our Dafne Valle attended the 2017 Texas ITE Spring Meeting in Frisco, Texas last week.  This is one of her updates from the meeting.

The Texas Spring Meeting of the Institute of Transportation Engineers offered attendees the opportunity to test drive a 2017 Audi with V2I technology through the City of Frisco.  Vehicle to infrastructure (V2I) relates to a communication exchange between vehicles and elements of transportation infrastructure that helps improve roadway safety.  The City of Frisco established a partnership with Audi of America, Trafficware and Traffic Technology Services Inc. (TTS) to stream real-time system and intersection data.

The first step was the installation of Trafficware’s “” Transportation Management System and Connected Vehicle Module on the City of Frisco transportation infrastructure.  This system streams real time signal system and intersection data to TTS.  Then TTS predicts the traffic signal state changes using their patented process.  Finally, TTS will deliver the signal phase and timing via messages using cellular communications to selected Audi vehicles.  Communications such as “time to green” and “reduce speed” will be provided for 2017 Audi models.

The City of Frisco will be the first city in Texas to provide this kind of technology to Audi vehicles.  Audi expects future deployments in other Texas metro areas such as Dallas – Fort Worth, Houston, Austin and San Antonio.
