Abstract

The invention provides a gradient induction control method. The method comprises the steps of obtaining traffic flow data of a target intersection at a current moment and operation data of a corresponding traffic signal lamp; according to the running duration of the target stage and the corresponding relation between the different running duration intervals of the lamp sets in the preset target stage and the vehicle number threshold values, gradient vehicle number threshold values corresponding to the lamp sets at present in the target stage are determined; according to the operation data, the traffic flow data and a gradient vehicle number threshold value, determining a stage vehicle state value and a stage pedestrian state value of the target stage at the current moment; according to the stage vehicle state value and the stage pedestrian state value of the target stage at the current moment, determining a stage signal value of the target stage at the current moment; determining a stage decision value of the target stage at the current moment according to the stage signal value of the target stage at the current moment; and according to the stage decision value of the target stage at the current moment, generating a control instruction for controlling the traffic signal lamp of the target intersection.
