Connected Vehicle Tour
TTS is proud to host a tour with one of our customers, Audi of America, during the upcoming 2018 ITE Quad Conference. This tour is open to all meeting participants.
What Will You Do?
Participants will drive around the venue to experience the connected vehicle applications. Read below for more details about the technology and Audi's application. It is encouraged that all participants drive the vehicle and experience the system, but it is not necessary to witness the system in action.
The entire demonstration will take 15-20 minutes total to drive through some signalized intersections and experience the system.
Must have a valid drivers license and be over 25 years old to participate as a driver in the demonstration.
Advanced reservations will be taken online to secure a time. Participants may also arrive at the TTS pick-up/drop-off site; first come, first served, but limited seats available.
Confirm Your Seat
Experience an Audi vehicle connected with the traffic signal infrastructure, and it will change the way you view V2I technology.
What Is the Product?
TTS develops SAE J2735 SPAT and MAP messages, with additional signal state predictions up to three changes, and provides those messages via our cloud solution. Our product name for this information 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?
We do not utilize Dedicated Short Range Communications (DSRC) to connect to the vehicle. In fact, we do not provide a connection into the vehicle, that is our customer's responsibility; our expertise is in prediction and content delivery. The Personal Signal Assistant® solution is entirely software based, and utilizes existing infrastructure communications to communicate to the traffic signal from an ATMS.
We work with existing signal control or ATMS vendors, as our business partners, 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 raw, real-time signal status information, we feed that information along with other historical information into our machine-learning prediction engine. In other words, we use several data sources to look at the most likely outcome for the traffic signal operations for the next one to two cycle lengths.
The following figure shows how data flows from the traffic signals to the vehicle:
Working with Agencies
TTS works with agencies to form a data sharing partnership and advance a vehicle-to-infrastructure deployment. TTS is working with agencies throughout North America. TTS currently has live products in California, Colorado, Oregon, Nevada, Texas, and Washington, DC. Arizona, Kansas, Florida, and Michigan will be the next states added to that list.
In exchange for granting access to the data, the City receives information about the system operation and experienced connected vehicle operations.
Working with Our Partner
In the case of the City of Portland, ODOT, City of Gresham, Clackamas County, and Washington County, TTS worked directly with TransCore to establish a connection via the City's network and ATMS system. The process took less than a day. No hardware to install, configure, or maintain.
Audi's Connected Vehicle Applications
Audi has been working on V2I technology for 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 2018 Q7, Q5, A5, and A4 models, and will be supported by all models in the future. More information on their system is available from Audi's Press Release.
This is the first step towards a fully automated and piloted future, as shown here:
Over the last several months, drivers of newer Audi vehicles have been receiving information about traffic signals for the remaining time to green when approaching a red traffic signal indication. During this event you will have the opportunity to experience the Audi connect® Traffic Light Information system on the streets of Portland, OR.
