摘　　要：共享街道是一种让人车共同使用街道空间,进而鼓励行人活动的设计理念,自20世纪60年代提出以来,已被多个国家采纳,并应用到实际建设中。文章运用空间句法与多源城市数据对新西兰Fort street、德国Bremer street、丹麦superkilen、荷兰Zuiderbuurt、英国Exhibition Road、西班牙C.de Carretas、中国上海苏州河虹口段7个建成的共享街道案例的机动性、可达性、可通行性、边界和视野进行分析,通过OSM数据和街景数据,分析共享街道的当前使用情况,并收集使用评价,总结了共享街道与人车分离街道在空间认知和安全方面的差异,并在此基础上从障碍物设置、隐性流线规划、街道界面层次感等方面,归纳有利于提高安全性的共享街道设计方法,以期为城市更新和街道复兴提供参考。Shared street is a design concept that allows vehicles,pedestrians,and non-motorized vehicles to share the same street space in order to encourage pedestrian activity.Ever since its introduction in the 1960s,this theory has been adopted in many countries and applied to the practice.This paper uses spatial syntax and multi-source urban data to analyze the mobility,accessibility,availability,boundaries and horizon of seven completed shared streets:Fort street(New Zealand),Bremer street(Germany),superkilen(Denmark),Zuiderbuurt(Netherlands),Exhibition Road(UK),C.de Carretas(Spain),and Suzhou River Hongkou section(China).By using OSM data and streetscape data,the current usage status of these shared streets was analyzed and usage evaluation results were collected.This paper compares the differences in spatial perception and safety between shared streets and normal streets,and on this basis,concludes the design methods of shared streets that are conducive to improving safety from the aspects of the setting of obstacles,the planning of hidden streamlines,and the hierarchy of street interfaces,in order to provide a reference for urban renewal and street renovation.
