The invention provides a planar crossroad signal control optimization method based on a vehicle queue length. By means of the method, the problem that currently only one traffic signal control optimization method is adopted and the crossroad real signal control optimization demands cannot be satisfied is solved. The method comprises the following steps of acquiring the start queue length lsij of each flow direction of a crossroad when a green light phase starts and the remaining queue length leij when the green light phase stops, wherein, the i is a signal phase sequence number and can be 1, 2, 3, 4, and j is the green light flow entry road direction inside the phase and can be E, W, S, N; (2) calculating the acceptable green time ratio Paij of each flow direction of the crossroad; (3) judging whether the crossroad requires phase congruency setting and determining the phase congruency duration if the crossroad requires phase congruency setting; (4) and optimizing the crossroad signal timing scheme according to the judgment result in the step (3).
