Abstract: Signal Phase and Timing (SPaT) messages are provided to control operation of a vehicle. A computer system receives switching state data (SD1) from one or more traffic lights and provides a SPaT message to the vehicle. The SD1 of a traffic light includes a pass-state (SD1p) and a stop-state (SD1s) data at respective sampling time points. A signal analyzer in the computer system analyzes the SD1 by: identifying the current signal state (SD1s, SD1p) of the one or more traffic lights; deriving, from a statistical model, probabilities for future state transitions for one or more future prediction intervals; and determining a minimum end time for a state transition from a current state to the different state. A message composer composes the SPaT message including the determined minimum end time.

Abstract: A traffic control system can includes a plurality of traffic lights. A monitoring system can include an inbound interface component, an analytics component, and an outbound status provisioning component. The inbound interface component can be configured to receive a stream of sensor data from visual sensor(s). Each visual sensor can be configured to capture light signals of traffic lights. Each traffic light can be sensed by the visual sensor(s). The received stream of sensor data can represent a current signal status of each traffic light. The analytics component can be configured to predict at least one future signal status for each of the traffic lights based on the use of a machine learning algorithm. The outbound status provisioning component can be configured to send a message(s) to a vehicle. The sent message can influence the operation of the vehicle.
