将网络结构熵的概念引入省际高速公路联网收费研究中。首先,建立了高速公路抽象化图论模型,在此基础上定义了收费网络结构,发现省界收费站是其中的关键因素。为研究收费网络结构变化机理,提出了收费站重要度和收费网络结构熵,并确定了网络结构熵的极值。其次,通过推导,得出省际联网收费网络结构熵大于省内联网收费网络结构熵,从而证明了实施省际联网收费的合理性。最后,提出了下一步研究的方向。
The concept of network structure entropy into the provincial highway network charging research. First of all, a highway abstract graph theory model is established, on the basis of which a fee network structure is defined and it is found that the provincial toll station is one of the key factors. In order to study the changing mechanism of charging network structure, the importance of charging station and the entropy of charging network structure are proposed, and the extreme value of network structure entropy is determined. Secondly, through the derivation, we can conclude that the entropy of inter-provincial network is larger than the entropy of network in the province, which proves the rationality of inter-provincial network charging. Finally, the direction of further research is proposed.
