Abstract: A traffic light control system configured to provide instructions to a traffic light for testing performance of an autonomous vehicle as it approaches the traffic light includes a controller. The controller includes a transceiver in communication with the traffic light and a computer-readable memory storing a plurality of operation routines for the traffic light. The controller is configured to: select an operation routine of the plurality of operation routines on the computer-readable memory; and provide a control signal via the transceiver to the traffic light to control operation of the traffic light according to the selected operation routine. Controlling operation of the traffic light includes turning on or off at least one of a plurality of light emitters of the at least one traffic light and/or changing a brightness, frequency, or intensity of at least one of the plurality of light emitters of the traffic light.

Abstract: A mounting device for selectively positioning an optical element within a field-of-view of an optical sensor of a vehicle includes: a housing defining an opening sized to fit over an aperture of the optical sensor; a holder for the optical element connected to the housing and positioned such that, when the holder is in a first position, the optical element is at least partially within the field-of-view of the optical sensor; and a motorized actuator. The motorized actuator can be configured to move the holder to adjust the position of the optical element relative to the field-of-view of the optical sensor.
