According to path planning problem of multimodal transportation for long and bulky cargo, this paper constructed the interference function to quantify the influence degree of long and bulky cargo transportation to normal transportation. Taking the minimum of total cost as the first optimization objective and the minimum of total interference degree as the second optimization objective, this paper developed a multi-objective path planning model of multimodal transportation based on the interference degree for long and bulky cargo. Considering the characteristics of research question and combining with the proposed construction algorithm of quasi-tri-prism network, this paper designed the path planning algorithm of multimodal transportation based on K-shortest paths. The calculation results of example show that the proposed method can formulate multiple sets of path planning schemes about multimodal transportation for long and bulky cargo, reduce the interference impact of multimodal transportation for long and bulky cargo and identify critical lines and nodes that affect the pros and cons of the scheme, so as to provide decision support for the transportation organization of long and bulky cargo.
