​US Patent Office grants TTS' 8th patent "System and method for providing real-time and predictive speed, traffic signal timing, station dwell time, and departure window information to transit vehicle Patent 11,113,957"
Devices, systems, and methods are disclosed for connecting traffic signal control infrastructure, in-service transit vehicles, and back-end computing and service systems, and providing an adaptable user interface remotely effecting a change on a Portable Electronic Device (PED), verifying location of transit vehicles and tailoring information to the behavior of a transit operator. System determines an "optimal window" for a transit vehicle to travel through a maximum number of consecutive traffic signals during the green vehicular phase. The system determines and sends a recommended speed to traverse the optimal window.

"What began as an initial deployment of next-generation cellular vehicle-to-everything (C-V2X) technologies has now yielded a wealth of insights to safety benefits in the real world for drivers, passengers, and vulnerable roadside workers. Together, Audi of America, American Tower, Commsignia, Qualcomm Technologies, Inc., Traffic Technology Services, the Virginia Department of Transportation, and Virginia Tech Transportation Institute (VTTI) were able to develop intuitive communications tools to alert drivers when they are entering work zones, including shifting traffic patterns, visibly and audibly notifying roadside workers when vehicles are close to a work zone, and building on Audi’s existing Traffic Light Information with new red light violation warnings."

US Patent Office grants TTS' 7th patent "Vehicle Dilemma Zone Warning Using Artificial Detection Patent 10,937,313"
At a roadway intersection controlled by an electronic traffic signal controller system, a potentially dangerous "dilemma zone" problem arises where a driver must quickly decide whether to stop or continue through the intersection. The problem is mitigated by leveraging data provided by an approaching vehicle itself as the source of detection. Based on the vehicle data itself, an "artificial detection" message is sent to the traffic signal controller to attempt to extend the green time, and thus permit a subject vehicle to safely pass through the intersection.

US Patent Office grants TTS' 6th patent "Traffic signal state prediction correction and real-time probe data validation Patent 10,878,693"
Traffic signal state predictions for fixed-time signals are generated based on their scheduled timing plan and the current clock/time, but these predictions are subject variations, for example, due to traffic signal controller clock drift. Real-time actual, not predicted, data is collected and utilized to correct for these variations. Further, real-time probe data is collected and used to validate correctness of the generated predictions in real time.

​TTS announces that its global deployment has reached the milestone of 30,000 signals. Deployment regions represent more than 30 metropolitan areas in the US, Canada and Germany and coverage has reached 15% of signals within the largest 25 US metropolitan areas.

TTS joined Virginia Department of Transportation (VDOT), Virginia Tech Transportation Institute (VTTI), American Tower, Qualcomm Technologies, Inc, and Audi for this C-V2X trial. TTS provided its patented traffic signal prediction which was fused with low latency near real-time status broadcasted directly from the traffic signals via C-V2X.

US Patent Office grants TTS' 5th patent "Configurable Virtual Traffic Detection System Under Predictive Signal States Patent (10,733,883)"

Computer-implemented predictions of upcoming traffic control signal states or state changes can be used to improve convenience, safety, and fuel economy. Such information can be used advantageously by a human operator, or by an autonomous or semi-autonomous vehicle control system. User (for example, driver) requests for a signal change may be implemented in traffic control systems, with all due care. User requests are validated and compared to traffic signal state change predictions. Only when appropriate conditions are met, the user request is used to generate a "synthetic call" to the applicable traffic signal controller (TSC). The new synthetic call substitutes for the usual call signal which arises from a fixed physical hardware detection system such as an inductive loop in the pavement.

​US Department of Energy’s National Energy Technology Laboratory has announced that the application titled “Energy Optimization of Light and Heavy Duty Vehicle Cohorts of Mixed Connectivity, Automation and Propulsion System Capabilities via Meshed V2V-V2I and Expanded Data Sharing” has been recommended by the Vehicle Technologies Office for negotiation of a financial award. The project team is led by Michigan Technological University and includes TTS and other team members such as AVL Powertrain Engineering Inc.

​TTS announces that its global deployment has passed the milestone of 25,000 signals. Deployment regions represent close to 30 metropolitan areas in the US, Canada and Germany.
