A GPS positioning technology-based traffic flow fusion monitoring method includes the steps of: (1) calculating space average speed of a floating car in a certain period of time in a selected road segment; (2) calculating time average speed detected by a ground sensing coil in the certain period of time in the road segment; (3) obtaining corresponding time average speed of the floating car; and (4) obtaining a calibration ratio of floating car data. The GPS positioning technology-based traffic flow fusion monitoring method proposes an algorithm of fusing vehicle instantaneous speed collected by the ground sensing coil with the space average speed collected by the floating vehicle, thereby obtaining calibrated road segment average speed, and improving monitoring precision of the road segment average speed.
