The invention provides a lamp path relation knowledge graph construction, relation prediction and automatic driving method, and according to the embodiment of the invention, the lamp path relation is determined, and assistance is provided for map navigation. The light path relation knowledge graph construction method comprises the following steps: acquiring information of traffic lights in target light path data and information of roads in a set range around the traffic lights; determining nodes representing the traffic lights and nodes representing the roads according to the information of the traffic lights and the information of the roads; generating edge data representing a correlation between the nodes; the mutual relation between the nodes comprises at least one of the mutual relation between the roads and the mutual relation between the traffic lights and the roads; and according to the nodes representing the traffic lights, the nodes representing the roads and the edge data, constructing a light road relation knowledge graph.
