if the vehicle is in the circumstance of overspeed, accident or their combination, the vehicle icon is set to be in a state of twinkling; and

the vehicle security information has the priority to be reported.

5. The method for dispatching vehicle of claim 1, wherein the virtual line schedule map also comprises a temporary mission box, a parking box and a maintenance box, and the step B further comprises:

B1. judging the vehicle states, wherein the vehicle states comprises up-state (2), down-state (3), on-the-initial-point state (1), on-the-terminal-point state (4), temporary mission state (5), in-maintenance state (6) and parking state (7);

B2. if the vehicle state is the up-state (2) or the down-state (3), placing the vehicle icon in the corresponding position in the up-line or the down-line based on the relative position of the vehicle and by the principle of ratio;

if the vehicle state is the on-the-initial-point state (1) or the on-the-terminal-point state (4), placing the vehicle icon in the corresponding initial point box or the terminal point box based on the principle of sequence;

if the vehicle state is the temporary mission state (5), the in-maintenance state (6) or the parking state (7), placing the vehicle icon in the corresponding temporary mission box or maintenance box or parking box.
