  • Patent number: 12367764
    Abstract: A system for optimizing traffic signal timing using telemetry includes: wirelessly connected devices (WCDs), traffic operations centers (TOCs) controlling one or more traffic signals, and control modules storing and continuously executing control logic in a closed loop. The control logic continuously receives real-time WCD telemetry data and performs real-time processing of the telemetry data to match the telemetry data to physical locations. Processed telemetry data is aggregated to determine WCD trajectories. The system selectively performs time-of-day (TOD), offset, and green split optimizations, and receives the WCD trajectories and outputs of the TOD, offset, and green split optimization within an API. The system generates an optimized signal plan from data from the API, and verifies the optimized signal plan. The optimized signal plan is received by the TOCs and selectively uploaded to the traffic signals.

  • Publication number: 20250173795
    Abstract: A system for measuring insurability based on relative vehicle operator performance (MIROP) includes sensors capturing host and remote vehicle information, and information about an environment of the host and remote vehicles. A controller executes a MIROP application that identifies event information within data obtained from the sensors, transmits, the event information to a cloud computing server, assesses a physical location and proximity of the host vehicle to remote vehicles participating in the system. The MIROP application assesses a road surface condition of a road segment upon which the host vehicle is traveling, estimates a traffic density on the road segment, aggregates host vehicle behavioral data and identifies event IDs within the behavioral data. The MIROP application computes a vehicle operator insurability score and automatically notifies an insurance carrier of the score as well as automatically presenting the score and suggestions to improve the score to a host vehicle operator.

  • Publication number: 20250142359
    Abstract: A system for predicting a user plane using control plane features and Granger causality includes a host device a cloud computing server and controllers. The controllers execute control logic including a prediction application (PA) that obtains sensor data from the sensors, sends control and user plane data to infrastructure, and to the cloud computing servers, and accesses prior knowledge data stored within memory of the cloud computing servers. Additional control logic performs a Granger causality test on the user and control plane data, and utilizes a prediction model to generate a prediction from fused user and control plane data. A prediction verifier is applied to the prediction from the prediction model, and the PA enables the host device to make reliable predictions that allow the host device to adapt to dynamic wireless communications network conditions even when a best possible model is not fully trained.
