1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the computer to:

  • collect data about vehicle movement at a stoplight;

    predict a first stoplight cycle time with a first probability model of the stoplight cycle time, the probability model indicating a first range of probabilities of the first predicted stoplight cycle time for;

    compare the collected data to the predicted stoplight cycle time to generate a second probability model, based on the first probability model, that specifies a second range of probabilities of a second predicted stoplight cycle time;

    apply a noise function to the collected data to generate noise-applied data;

    update the second probability model for the predicted stoplight cycle time by adjusting a set of probabilities of the second probability model with the noise-applied data to generate an updated second probability model; and

    provide, via a network to at least one vehicle computer, a recommended vehicle operation based, at least in part, on the predicted stoplight cycle time determined by the updated second probability model.
