Abstract:
In order to measure the functions of highway network reasonably, and through systematic analysis of the status quo about researches on accessibility of highway network, the authors improve the connotation of accessibility of highway network so as to find the defects existing in the current researches which lack the consideration about transport demand and it's degree of realization. The conclusion made in this study is that accessibility of highway network can be understood from two aspects:space accessibility and transportation accessibility. However, there is scarce study about transportation accessibility. The purpose of highway construction is providing service for transportation. Therefore, the accessibility that doesn't consider the transport demand is only space accessibility of highway network, and it can not reflect the whole function of accessibility. Space accessibility can be considered from the state and economic rationality, and transportation accessibility is considered from transportation adequacy and transportation users' economics under the highway network supply. As there exist the defects that the current methods in calculating the accessibility of highway network fail to reflect the reasonablity of highway grades, the transportation adequacy and transportation users' economics, the authors improve the current the model to measure the accessibility of highway network, which is of great theoretical significance.
