Abstract
The accessibility of the port collection and distribution system is an important factor affecting the scope of the port hinterland. Based on the BPR function, this paper proposes economic, time and environmental cost factors applicable to multiple transportation modes, and constructs an accessibility measurement model based on the generalized cost impedance function. Finally, we take the Douala port as an example to verify the model, the results shown that the accessibility of each logistics node is reduced by 73.66% on average after the environmental cost factor is added, and different nodes show different degrees of decline, meanwhile the advantages of waterway and railway transportation in environmental cost factors and logistics cost factors are more prominent. In summary, the accessibility measurement model based on the generalized cost impedance can more comprehensively reflect the accessibility characteristics of the port collection and distribution system.
