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.
