Vehicle scheduling method and system for intersection without signal lamp

The invention discloses a vehicle scheduling method and system for an intersection without a signal lamp, and the method comprises the steps: obtaining to-be-passed vehicles at the intersection without the signal lamp, and dividing the to-be-passed vehicles into a vehicle team form; determining two motorcades closest to the intersection, and judging whether the moving trajectories of the two motorcades passing through the intersection have an overlapped region or not; if not, the two motorcades do not collide with each other, and the two motorcades are controlled to normally pass through the intersection; if yes, the two motorcades have the possibility of collision, and the overlapping area is the possible collision area; calculating the time when the two motorcades arrive at the possible collision area, controlling the motorcade which firstly arrives at the possible collision area to pass preferentially according to the principle of coming first and then passing later, and controlling the other motorcade to
