Claim:
1. A computer implemented traffic simulation method for sequentially calculating the positions of a plurality of vehicles traveling along roads according to a time interval, wherein the computer includes a processor communicatively coupled to a memory, the method comprising: calculating a filling rate of an at least one vehicle at an intersection; selecting a plurality of top N intersections with respect to said filling rate; adding up a plurality of filling rates with respect to said plurality of top N intersections to get an added-up filling rate; calculating said time interval of a simulation by dividing the number of intersections as measurement objects×the total number of nodes×the number of vehicles in the entire simulation by a square of said added-up filling rate×the number of steps in the entire simulation; advancing said simulation at said calculated time interval; and outputting, to a display, updated positions of the plurality of vehicles according to said calculated time interval.
