1. A computer-implemented method comprising:

  • identifying, by one or more computing devices, a time when a traffic signal light will turn from yellow to red;

    estimating, by the one or more computing devices, a location of a vehicle at the identified time that a traffic signal light will turn from yellow to red;

    detecting, by the one or more computing devices, a starting point of an intersection associated with a traffic signal light;

    determining, by the one or more computing devices, whether the estimated location of the vehicle is at least a threshold distance past the starting point into the intersection;

    when the estimated location of the vehicle is determined to be at least a threshold distance past the starting point into the intersection, determining, by the one or more computing devices, that the vehicle should continue through the intersection;

    after determining that the vehicle should go through the intersection, estimating, a second location of the vehicle at the time that the traffic signal light will turn from yellow to red; and

    determining whether the estimated second location of the vehicle is at least a second threshold distance past the starting point, wherein the second threshold distance is less than the threshold distance.
