| 摘 要： | 首先在总结现有城市道路分级理论存在的不足基础上,从道路在路网中承担的结构功能角度指出,道路骨架性是城市道路分级方法的重要依据.然后提出了道路骨架性的定义,采用介数中心度作为定量描述道路骨架性的计算指标,并建立了依据道路骨架性定量划分道路等级的计算分级法;最后采用多个城市的现状与规划道路网数据,比较了计算分级法和传统道路分级方法所得到的道路分级结果的相似程度,验证了所提出的计算分级法的合理性和可行性.

| Abstract: | The traffic function of each road in network was determined by its structure function to a large extent, so the conventional urban road hierarchy is effectively based on road network topology. Therefore, this study firstly defined the arteriality of roads as an indicator to describe the relative importance of road in network topology, and use betweenness centrality to calculate the arteriality of each road, then proposed a new method of road hierarchy by quantitatively calculating the arteriality of each road in the network. Finally, we verify the reasonability of this new method by compared the results of conventional road hierarchy method and this new calculation method. |
