The two geomagnetic devices 8 at the entrance end of the lane output level signals to the communication module 74, and the communication module 74 transmits the level signals to the control system, and the control system calculates the number of vehicles according to the change frequency of the level signals. If the waiting vehicles before the green light is converted are not dredged when the signal light is forcibly converted into the red light, the number of the vehicles which are not dredged is saved, and the number of the subsequent vehicles is increased on the basis, so that the number of the vehicles which are currently detained in the lane can be calculated. In addition, the two geomagnetic devices 8 at the exit end of the lane output the same level signal to the communication module, the communication module transmits the signal to the control system, the control system calculates the vehicle flow rate according to the time interval when the vehicle passes over the two geomagnetic devices 8 at the same lane, calculates the distance according to the final vehicle number and the average vehicle length, and divides the distance with the vehicle flow rate to obtain the passing time; the vehicle flow rate changes in real time, and the current remaining transit time is updated according to the real-time vehicle flow rate.

Continuing to take the example shown in fig. 1 as an example, when the signal lamps corresponding to the right lane are changed into red lamps, the control system analyzes and calculates the number of vehicles in the lane, updates the priority of the signal lamps, judges whether the number of vehicles in the lane reaches the upper limit, if so, immediately and forcibly converts the signal lamps corresponding to the right lane into green lamps, and the signal lamps in other three directions of the lamp-controlled intersection are all red lamps; if not, adjusting to the normal lighting period of the traffic lights. The induction mode is used for adjusting the lighting cycle time of the signal lamp, so that the delay of the road section is avoided; in addition, if the vehicles detected by the geomagnetic devices 8 on the lanes in the four directions at the lamp-controlled intersection are smooth, that is, the traffic flow is small, the control system controls the signal lamps facing the lane on the right side to be appropriately adjusted to turn on yellow lamps, so as to ensure smooth traffic at the intersection.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
