The invention provides a method and device for controlling traffic signals of intersections. The method for controlling traffic signals of intersections comprises the following steps: (1) detecting whether the road between an upstream intersection and a downstream intersection is congested or not by a congestion detector, wherein the congestion detector is arranged between the upstream intersection and the downstream intersection; and (2) if the road is congested, prolonging the time of the green light of the downstream intersection or shortening the time of the green light of the upstream intersection. When the road is congested, by prolonging the time of the green light of the downstream intersection, vehicles on the congested road can pass through the downstream intersection and run away from the congested road because of longer green light time, so that the congested road can be unblocked quickly; or by shortening the time of the green light of the upstream intersection, the number of the vehicles running on the congested road is reduced, so that the congested road can also be unblocked quickly, thereby realizing the purpose of reducing the occurrence of the phenomenon that the traffic capacity of the road network in a large range is lowered because a single intersection is congested.
