Audi connect Traffic Light Information
TTS, along with the District Department of Transportation, is proud to host a connected vehicle demonstration with one of TTS' customers, Audi of America, during the ITS America Annual Meeting. This demonstration is open to all meeting participants.
What Will You Do?
Participants will drive around the convention center to experience the connected vehicle applications developed by Audi. Read below for more details about the technology, TTS' service, and Audi's application.
The entire demonstration will take 30-45 minutes total to drive through signalized intersections, experience the system, and discuss the technology during the drive.
Must have a valid driver's license and be over 25 years old to participate as a driver in the demonstration.
Advance registrations are being taken online to secure a demonstration time. Limited availability.
Experience an Audi vehicle connected with the traffic control infrastructure. It will change the way you view V2X technology.
What Is the Product?
TTS develops SAE J2735 SPAT and MAP compliant messages, with additional signal state predictions up to three changes, and provides those messages via our private cloud solution. Our product name for this information as a service is Personal Signal Assistant®. TTS customers, in various transportation sectors, utilize the messages for connected vehicle applications for driver information, powertrain efficiency, automated driving, and/or safety applications.
How Does It Work?
Our expertise is in prediction and information delivery. The Personal Signal Assistant® solution is entirely software based and utilizes existing infrastructure communications to the traffic signal from an ATMS.
We partner with existing signal control or ATMS vendors to deliver data in a secure and responsible manner. Our partner network utilizes existing CV interfaces or our API to develop the connection and transfer data about the traffic signal operations.
Once we receive the real-time traffic signal status data, we feed that source along with other historical information into our machine-learning prediction engine. In other words, we use several data sources to simulate the most likely outcome for the traffic signal operations for the next one or two cycle lengths.
The following figure shows how data flows from the traffic signals to the vehicle:
We do not utilize Dedicated Short Range Communications (DSRC) or C-V2X (5G) to connect to the vehicle. In fact, we do not provide a connection into the vehicle; it is our customer's responsibility to make a connected vehicle.
TTS works with agencies to execute a data-sharing partnership and advance a vehicle-to-infrastructure deployment. TTS is working with agencies throughout North America and currently has live service in Arizona, California, Colorado, Florida, Georgia, Kansas, Michigan, Missouri, Nevada, New York, Ontario, Oregon, Texas, Virginia, Washington, and Washington, DC. The next states/provinces added will be Connecticut, Indiana, Manitoba, North Carolina, North Dakota, and Tennessee.
In exchange for granting access to the data, the agency receives information about the system operation and experienced connected vehicle operations.
In the case of District Department of Transportation, TTS worked directly with the agency to establish a connection via the agency's open data portal. In other locations, we work with our Partner network to establish a secure connection between vendor ATMS systems and the TTS servers.
Audi's Connected Vehicle Applications
Audi has been working on V2I technology for well over a decade.
At CES 2014, TTS and Audi demonstrated a proof of concept of how the system could work. Almost three years later, in December 2016, we launched the Personal Signal Assistant® service for commercial applications concurrent with the launch of Audi connect® Traffic Light Information.
Audi has provided the first commercial V2I service with the launch of the Traffic Light Information feature available with Audi connect® Prime. The service is now supported in all 2019 models. More information on their system is available from Audi's latest Press Release.
This is the first step towards a fully automated and piloted future, as shown here:
State of Infrastructure - Washington, DC
Over the last three years, TTS has been building an inventory of signalized intersections throughout the greater Washington, DC metro area (including Baltimore). By the numbers:
These numbers are not final, but they give a good indication of the state of the traffic control infrastructure in the metro area.
TTS has been active with several agencies in the area to bring their signals online. Here is the current status of TTS' deployment in Washington, DC:
