The invention discloses a regional traffic dynamic signal control method and system based on real-time holographic perception. The method comprises the following steps: calculating a key intersection flow ratio according to a phase flow ratio corresponding to each phase; calculating the period green time ratio of the key intersection according to the period effective green light duration and the period duration of the key intersection, and calculating the saturation of the key intersection according to the flow ratio of the key intersection and the period green time ratio of the key intersection; if the saturation degree of the key intersection is within a first saturation degree range, a first signal instruction is generated, and the first signal instruction is used for carrying out single-point adaptive optimization control on all intersections with the minimum number of parking times as a target in the optimization area; and if the saturation degree of the key intersection is within a second saturation degree range, a second signal instruction is generated, and the second signal instruction is used for carrying out trunk line green wave coordinated optimization control on the trunk line intersection and carrying out single-point adaptive optimization control on the single-point intersection in the optimization area by taking the minimum delay time as a target.
