Modeling And Optimization Of The Highway And Waterway Consolidation And Distribution System In The Container Port Cluster Of Guangdong Province

The external trade of Guangdong Province develops fast on the benefit of the reform andopening-up policy. The rapid development of export-oriented economy has brought a lot ofcargo transport demand and led to the rise of ports, formed container port cluster with thecharacteristics of sharing hinterland. With cargo transport demand continues to increase, roadtransportation capacity is becoming saturated, but inland water transportation with naturaladvantages and good policy support is lagging behind. Otherwise, with the urban congestionand environmental pollution, low-carbon transport is extremely needed. Therefore, we need acomprehensive analysis of the consolidation and distribution system and adjust the percentageof each transportation mode, improve the status of inland water transportation, optimize theallocation of resources. The consolidation and distribution system is a complex system whichconsists of nodes, transportation modes, transportation networks, vehicles, organizationmanagers, information resources and other components. As part of the system, transportationnetwork coupled hinterland and port, its performance and efficiency is linked directly to theoverall development of the system.Taking the consolidation and distribution system of Guangdong Province as case, thispaper focuses on system modeling among179hinterlands,227highway nodes,7sea portsand88waterway nodes, which contains36inland container port nodes. Then, connectivityindicators and topological property indicators are used to analyze the highway and waterwaynetwork, combined with graph theory and complex network theory. In addition, this paperweighted the network with capacity and distance respectively and calculated relevantindicators. Finally, using the comparative analysis of flow and capacity, key nodes and roadsare founded. Meanwhile, which mode is more suitable for low carbon logistics is foundthrough quantitative analysis. As such, this paper proposes suggestions for scientific networkplanning, management of critical nodes and encouragement of inland waterway transportationto ensure the coordinated development of economy and transportation.
