Abstract
In order to grasp the distinct roles of different highway network nodes, a hierarchical division method is built to measure the highway network node functions in the article. The problems of existing node hierarchical division method and corresponding influencing factors are deliberated by system analysis method, according to transportation demand theory and gray system theory. Then, combined with transportation demand characteristics, four influence factors of highway network node hierarchical division are proposed, and the gray node hierarchical division method is constructed based on gray system theory. On this basis, the authors pose an empirical analysis of the highway network nodes in Shandong province. The results of instance verification are demonstrated to be closer to reality. Consequently, the advanced method provides a reference for highway network programming.
