The invention discloses an intersection road area expansion method based on dynamic lane design, and relates to the field of traffic engineering. The method comprises the following steps: firstly, carrying out traffic investigation, and collecting traffic basic data of an intersection to be implemented; secondly, proposing a lane allocation scheme and a main signal timing scheme under a limited area according to dynamic lane design index requirements; then, determining the design length of the dynamic lane; and finally, determining a pre-signal timing scheme. The invention further discloses an intersection road area expansion system based on the dynamic lane design, the method is suitable for expansion of the intersection with the limited road area, the traffic efficiency of straight movement is not affected while the traffic capacity of left-turn movement is improved, the traffic capacity of urban intersections is improved, and the traffic efficiency of the urban intersections is improved. And the urban traffic jam problem is relieved.
