针对线下“打卡”成为城市流行，本研究基于城市传播的视角，选择北京的五道营胡同作为个案，通过参与式观察、深度访谈与问卷调查剖析街道空间和城市漫游者的空间实践，衡量人与城市间传播系统的可沟通性。
胡同具有包容多重文化的混杂空间特质：从物质上保护和延续了历史遗存与传统文化，以日常生活景观和休闲功能凸显地域市井文化，吸引多元人群并容纳了现代与国际文化。人在胡同中能够通过行走的具身实践建立理性与感性结合的认知系统，过滤并改编胡同主导的空间叙事，以日常惯习和人际交往占领公共空间。
人们基于城市空间实践和日常生活体验构建城市意义网络，并以此形成对城市的情感归属。胡同中的人情氛围与休闲活动，具身实践与人际社交体验使人逃离现代社会的异化。然而人与城市的稳固联系难以因以空间实践为主的城市活动形成，而更多是个体身份塑造的方式。
本研究将街道的可沟通性总结为基础设施上的便利畅通和虚实互嵌，意义传递上的多元融合与时空平衡，社会交往上的多样形态和圈层拓展，人之主体性上的意义阐释与艺术创造。街道是人与城市沟通的媒介，行走的空间实践为人地沟通的界面，可沟通性体现于“人—街道—城市”这一传播网络的畅通。

Based on the perspective of urban communication, this study selects the Wudaoying Hutong in Beijing as a case study to analyze the spatial practices of street and urban wanderers through participatory observation, in-depth interviews and questionnaires, and to measure the communicability of the communication system between people and the city.
Hutongs are mixed spaces that embrace multiple cultures: they physically preserve and perpetuate the historical heritage and traditional culture, highlight regional urban culture with daily life landscapes and leisure functions, attract diverse people, and accommodate modern and international cultures. In the hutongs, people can establish a cognitive system combining rationality and sensibility through the embodied practice of walking, filter and adapt the hutong-dominated spatial narrative, and occupy the public space with daily habits and interpersonal interactions.
People construct urban meaning networks based on urban spatial practices and daily life experiences and form emotional belonging to the city in this way. The human atmosphere and leisure activities in hutongs, embodied practices, and interpersonal social experiences allow people to escape the alienation of modern society. However, the solid connection between people and the city is hardly formed by urban activities based on spatial practices, but more as a way to shape individual identity.
This study summarizes the communicability of the street as a convenient and interlocking infrastructure, a multifaceted and spatiotemporal balance in the transmission of meaning, a variety of forms and circle expansion in social interaction, and the interpretation of the meaning and artistic creation in human subjectivity. The street is the medium of communication between people and the city, and the spatial practice of walking is the interface of communication between people and places.
