The invention relates to a ramp coordination control and guidance method for a bottleneck of a double-layer highway, belongs to the technical field of traffic management and control, and aims to solvethe problem of congestion in different conditionsof a single-layer highway or a double-layer highway. The method comprises the steps: applying ramp coordination control and guidance on an expressway,and arranging devices comprising traffic flow detectors, ramp signal control lamps and variable information boards; respectively calculating single-point regulation rates of the entrance ramps of thethree-dimensional expressway and the ground layer expressway by using an Alinea algorithm; judging whether ramp coordination control needs to be carried out on the bottleneck of the three-dimensionaland ground layer expressways according to the traffic flow parameters; and finally, activating single-layer ramp coordination control according to coordination regulation rate calculation under single-layer or double-side bottleneck congestion, calculating the optimal regulation rate of the single-layer expressway by using a Bottleneck algorithm, and starting ramp control. The method is used fora traffic system composed of the three-dimensional layer expressway and the ground layer expressway, and normal operation of the whole traffic system is effectively guaranteed.
