The invention discloses an intelligent traffic management system, which comprises a cross beam, a vertical beam, a signal light, a tachymeter, a range finder, a control unit, a display screen, a camera and a speaker. The signal light, the tachymeter, the range finder, the display screen and the camera are arranged on the cross beam, one end of the cross beam is connected to the top of the verticalbeam, the vertical beam is fixed at the intersection, and a speaker is placed on the opposite side of the intersection where the vertical beam is located; the control unit is arranged on the verticalbeam, and the signal light, the tachymeter, the range finder, the display screen, the camera and the speaker are connected to the control unit. The system detects the vehicle in a certain range of the intersection, calculates the movement state of the vehicle and the distance with the stop line, and calculates whether the target vehicle can pass the intersection stop line; and when the control unit determines that the target vehicle cannot pass the intersection stop line, warning is sent to the target vehicle. The system can improve the efficiency of the vehicle passing through the intersection when the signal light is green, and judge the non-passed vehicle in advance, which plays an important role in relieving urban traffic.
