Types and characteristics analysis of integrated transportation corridors

Integrated transportation corridor classification is one of the basic elements of the integrated transportation theory. In this paper, the existing problems of integrated transportation corridors classification are first analyzed. The existed corridor types and characteristics are summarized in terms of spatial level, transportation modes, and service objects, and relevant content has been added and improved. Then, transportation corridor types based on service features and functional characteristics are proposed, and characteristics analysis is also conducted. The results indicate that the classification based on service features and functional characteristics can not only reflect the supply and demand of corridors, but directly show the function of corridors. Finally, the proposed corridor classifications are analyzed with a case.
