The invention belongs to the technical field of road traffic, and discloses a waiting time self-regulating signal lamp, which comprises an electricity storage device, a controller, a wire harness, photographic devices, infrared devices and a signal transmitting and receiving device, wherein the electricity storage device and the controller are both arranged in a control box; the photographic devices are all arranged on a cross rod; the distances between points measured by the first, second and third photographic devices and a vertical rod are 10 meters, 30 meters and 50 meters, respectively; the distances between points measured by the first, second and third infrared devices and the vertical rod are 20 meters, 40 meters and 60 meters, respectively. The congestion condition of a road can be judged by the controller according to measurement results of the photographic devices and the infrared devices, so that the signal of a signal lamp can be regulated in real time. The signal lamp is reasonable in design, simple in structure and applicable to the optimal design of intersection signal lamps.
