Abstract: A method for determining a time length for developing a timing plan of traffic light control is disclosed. The method comprises the steps of: acquiring a first image at a preset time point before a red light of a traffic light is turned off, wherein the first image includes vehicles stopped at the red light; preprocessing the first image to generate a second image; extracting features from the second image by an artificial intelligence algorithm to generate a feature information, and determining a position relationship between vehicles on multiple lanes in the first image based on the feature information; and, determining the time length by the artificial intelligence algorithm according to the determined position relationship.
