Abstract: The traditional setting of a cycle length is based on the goal of the minimum total delay, while the green ratio is proportional to vehicle flow ratio in a phase, and large-sized vehicles and miniature vehicles are converted to standard vehicles, but the conversion ratio is not necessarily reasonable from the perspective of energy consumption. In this paper, the optimization goal of the cycle length is minimum energy consumption, and the green ratio was determined by the ratio of energy consumption and the degree of saturation in a phase, which aims to save the energy under the premise of unimpeded traffic at an intersection.
