摘　　要：城市层面,出行在街道的聚集程度能够体现不同街段对城市公共生活的意义。既往街道网络量化研究存在局限性。基于空间句法线段模型改进,将对街段的研究置于城市街道网络中,从城市层面评价出行在不同街段中的聚集度:首先,收集研究区域基础数据,选取适宜拓扑半径,运用空间句法线段模型计算各出行方式的街道网络可达性;其次,依据不同出行方式在当地占比,进行附加权重的叠合计算,对街道网络聚集度进行分级与评价;最后,探讨街道网络出行聚集度评价对沿街空间功能的调整与容量的框定,以及关键性节点与街段的选取及再设计方面的意义。街道网络出行聚集度评价为全局性认识各街段的城市公共生活价值提供参考,有助于面向城市公共生活回归的街道设计。At the urban level, the aggregation degree of travels in the streets can reflect the significance of different street segments on urban public life. There are limitations in the previous quantification research on street network. Based on the improvement of the space syntax segment maps, the paper proposed to evaluate the travel aggregation degree of street segments at the urban level by placing them in the urban street network. First of all, the data of study area was collected, and the topological radius of common travel modes were selected to format the segment maps. Then, the accessibility of models with different travel modes was analyzed. Secondly, taking the proportion of different travel modes as weight, the superposition calculation of additional weights was performed, and the models were classified and evaluated in terms of the travel aggregation degree of street networks. Finally, the effects of street network’s travel aggregation degree evaluation on function adjustment and capacity improvement of space along street were discussed, as well as the significance of selection and renewal design of key street intersections and segments. The study could provide a method for the overall understanding of street segments’ value on public life. It could be a design reference for the return of public life to the street.
