摘要： Traffic signal timing may be altered as a function of determining occluded signal viewing. More particularly, processing units may determine that a view of a traffic signal by a person is obstructed by a large vehicle located on a first ingress path to a roadway intersection with a second ingress path. The traffic signal controls the right of way of the first ingress path, and the person with the obstructed view is travelling along the first ingress path toward the intersection and is located behind the large vehicle relative to a view sightline of the person to the traffic signal. In response to the occluded view determination, a transition of the traffic signal may be delayed from a current visual display of a proceed signal to a subsequent visual display of a stop signal, until an end of a delay period.
