Abstract
Among other things, one or more travel signals are identified by analyzing one or more images and data from sensors, classifying candidate travel signals into zero, one or more true and relevant travel signals, and estimating a signal state of the classified travel signals.

A method comprising:
- causing a vehicle to drive autonomously on a road;
- automatically detecting a travel signal, comprising:
- identifying, in an image derived from signals of a sensor, a representation of the travel signal, the identifying being based on matching characteristics of the representation of the travel signal to predefined criteria;
- estimating a signal state of the travel signal, the estimating comprising:
- evaluating, use one or more sensors corresponding to the vehicle, a flow of traffic in a neighborhood proximate to the vehicle, and
- determining, using the flow of traffic, the signal state of the travel signal;
- and
- automatically controlling a maneuver of the vehicle based on the signal state.

A method comprising:
- causing a vehicle to drive autonomously on a road;
- automatically detecting a travel signal, comprising:
- identifying, in an image derived from signals of a sensor, a representation of the travel signal, and
- determining a correspondence between the representation of the travel signal and a true travel signal;
- estimating a signal state of the travel signal, comprising:
- detecting one or more additional travel signals in a direction of travel of the vehicle,
- estimating signal states of the one or more additional travel signals, and estimating the signal state of the travel signal using the signal states of the one or more additional travel signals;
- and
- automatically controlling a maneuver of the vehicle based on the signal state.
