    Abstract: Systems and methods are provided for interpreting traffic information. A method includes: receiving, by a processor, visual data from vehicles, wherein the visual data is associated with an intersection of a roadway having one or more lanes; receiving, by the processor, vehicle data from the vehicles, wherein the vehicle data is associated with the intersection of the roadway; determining, by the processor, a first state of a traffic light associated with the intersection based on the visual data; determining, by the processor, a second state of the traffic light associated with the intersection based on the vehicle data; correlating, by the processor, the first state and the second state based on a time synchronization; assigning, by the processor, the traffic light to a lane of the roadway based on the correlating; and communicating, by the processor, the traffic light to lane assignment for use in controlling a vehicle.

    Abstract: Systems and methods to perform traffic signal management for operation of autonomous vehicles involve obtaining vehicle data from two or more vehicles at an intersection with one or more traffic lights. The vehicle data includes vehicle location, vehicle speed, and image information or images. A method includes determining at least one of three types of information about the one or more traffic lights based on the vehicle data. The three types of information include a location of the one or more traffic lights, a signal phase and timing (SPaT) of the one or more traffic lights, and a lane correspondence of the one or more traffic lights. The method also includes providing the at least one of the three types of information about the one or more traffic lights for the operation of autonomous vehicles.

    Abstract: A digital key sharing system includes an electronic circuit and a first server computer. The electronic circuit is configured to store a plurality of digital keys, receive a plurality of key sharing requests, and generate a plurality of features in response to the plurality of key sharing requests. The first server computer is in wireless communication with the electronic circuit and is configured to generate an alert signal in response to finding one or more anomalies in the plurality of features to initiate a notification to a primary user device associated with the electronic circuit, and send a suspend notification signal to the electronic circuit in response to the finding of the one or more anomalies in the plurality of features. The electronic circuit is further configured to suspend use of the plurality of digital keys in response to reception of the suspend notification signal.
