    摘要: 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. The optimized signal plan increases throughput of traffic by decreasing total delays, and quantities of stops.

    摘要: Presented herein are adaptive power assist systems for manually-powered vehicles, methods for operating/constructing such systems, and motorized operator-powered vehicles with adaptive power assist systems. A method for regulating a power assist system of a manually powered vehicle includes a vehicle controller determining path plan data that includes a predicted route plan to traverse from a current vehicle location to a desired vehicle destination. A resident wireless communications device receives, from a remote computing node, an assist level power trace for operating the vehicle's tractive motor on the predicted route plan. The vehicle controller receives health level data specific to the vehicle user, determines a power assist delta based on the health level data, and modifies the assist level power trace based on this power assist delta. The vehicle controller transmits command signals to the tractive motor to output a selectively variable torque according to the modified assist level power trace.
