Method and device for determining traffic route for transportation of heavy objects on road

The embodiment of the invention discloses a method and a device for determining a road large transportation passage route, and the method comprises the steps: obtaining basic data, which comprises target vehicle attribute data, large vehicle historical data, road data and other road traffic influence data; establishing a road feature knowledge graph based on the basic data, wherein indexes for establishing the road feature knowledge graph comprise length limit, width limit, height limit, load limit, road blocking, charging standard and congestion degree; matching the attribute data of the target vehicle with the knowledge graph, identifying a key passage path, and constructing a large transportation path network topological graph of the target vehicle based on the key passage path; and identifying a final passage path in the large transport path network topological graph according to passage indexes, wherein the passage indexes comprise an economic index, a quickness index and a safety index.
