Traffic signal response for autonomous vehicles
First Claim
1. A computer-implemented method comprising:
- identifying, by one or more computing devices internal to a vehicle, a time when a traffic signal light will turn from yellow to red;
estimating, by the one or more computing devices internal to the vehicle, a location of the vehicle at the identified time that a traffic signal light will turn from yellow to red;
detecting, by the one or more computing devices internal to the vehicle, a starting marker at an intersection associated with a traffic signal light while the vehicle is in motion;
determining, by the one or more computing devices internal to the vehicle, whether the estimated location of the vehicle will be at least a threshold distance past the starting marker into the intersection; and
when the estimated location of the vehicle is determined to be at least a threshold distance past the starting marker into the intersection, determining, by the one or more computing devices internal to the vehicle, that the vehicle should continue through the intersection.

Abstract
Aspects of the disclosure relate to determining whether a vehicle should continue through an intersection. For example, the one or more of the vehicle'"'"'s computers may identify a time when the traffic signal light will turn from yellow to red. The one or more computers may also estimate a location of a vehicle at the time when the traffic signal light will turn from yellow to red. A starting point of the intersection may be identified. Based on whether the estimated location of the vehicle is at least a threshold distance past the starting point at the time when the traffic signal light will turn from yellow to red, the computers can determine whether the vehicle should continue through the intersection.

10. A system comprising one or more computing devices internal to a vehicle configured to:
-
identify a time when a traffic signal light will turn from yellow to red; estimate a location of the vehicle at the identified time that a traffic signal light will turn from yellow to red; detect a starting marker at an intersection associated with a traffic signal light while the vehicle is in motion; determine whether the estimated location of the vehicle will be at least a threshold distance past the starting marker into the intersection; and when the estimated location of the vehicle is determined to be at least a threshold distance past the starting marker into the intersection, determine that the vehicle should continue through the intersection. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory, tangible computer-readable storage medium on which computer readable instructions of a program are stored, the instructions, when executed by one or more processors, cause the one or more processors internal to a vehicle to perform a method, the method comprising:
-
identifying a time when a traffic signal light will turn from yellow to red; estimating a location of the vehicle at the identified time that a traffic signal light will turn from yellow to red; detecting a starting marker at an intersection associated with a traffic signal light while the vehicle is in motion; determining whether the estimated location of the vehicle will be at least a threshold distance past the starting marker into the intersection; and when the estimated location of the vehicle is determined to be at least a threshold distance past the starting marker into the intersection, determining that the vehicle should continue through the intersection. - View Dependent Claims (20)
