摘　　要：为了评价城市路网中每条道路的重要性,借助于拓扑网络结构,提出了一种评价方法。该方法借助对偶拓扑网络动态变化下的节点度量指标,通过Hosoya指标度量删除的节点对拓扑网络连通性的破坏程度,来评价道路重要性,并根据Hosoya指标对节点度量指标下的重要道路集合进行集合运算得到道路重要等级。以武汉市二环与三环间4个局部路网样本为例,发现集合运算后的Hosoya指标低于单一节点度量指标下的Hosoya指标,验证了该方法的有效性,并表明多指标集成相对于单一指标能更好地表达出道路重要性。To evaluate the importance of each road in the urban road network, an evaluation method was proposed using a topological network structure. This method utilizes node metrics under dynamic changes in dual topology networks to evaluate the importance of roads by measuring the degree of damage to topology network connectivity caused by node deletion using the Hosoya index. Based on the Hosoya index, the important road sets under the node metric are aggregated to obtain the road importance level. Taking four local road network samples between the second and third ring roads in Wuhan as examples, it was found that the Hosoya index after set operation is lower than the Hosoya index under a single node measurement index, verifying the effectiveness of this method and indicating that multi indicator integration can better represent the importance level of roads compared to a single indicator.
