Coordination Degree Evaluation of Multiple Transport Modes of Comprehensive Transport Corridors in the Silk Road Economic Belt

The proposal of building the Silk Road Economic Belt aiming to strengthen cooperation among Asian and European nations will benefit all the people along this Economic Belt. To establish the Silk Road Economic Belt, implementation of comprehensive transport corridors, including multiple transport modes, is foremost. Accordingly, the evaluation of coordination of multi-modes is a valuable foundation issue. This study constructs the coordination degree evaluation model of multiple transportation modes on the basis of the DEA principle. The model can calculate the coordination degree among multiple subsystems. The key idea of the evaluation model is that the output parts of the one subsystem could be regarded as the input parts of another subsystem. Then, the correlation level of the input and the output can be used to measure the coordination degree of the two subsystems. Furthermore, an application instance, based on some classical western regions that mostly involved in railroads and motorways, in the Silk Road Economic Belt, has been discussed in detail. Results of the application instance illustrate the coordination situation, trend, and improvement measures.
