基于多源数据和数字技术集成的城市街道空间安全改善策略研究

Over the past decade, the world has witnessed growing threats to the safety and security of cities and towns. Street, the public space where people commute, walk, go shopping, stay, and live, has played a key role in making our cities safe and secure for generation to come. Taking street space in Beijing City as example, this research explores the effects of physical street space on urban safe performance. It integrates multi-sources data on urban safety and security issues, remote sensing data, and GIS technical approaches into a digital analysis platform to test the hypothesis of “space-safety” relationship, and then adopts BIM and Agent-based system to simulate environmental behaviors in certain streets so as to found effective urban design strategies for enhancing physical performance and promoting urban safety...The research fills up the gap between street-scale physical design activities and urban safety and security research. Through establishing a digital technical integrated working platform, the research analyzes roles that street space plays in impacting urban safe circumstance involving crime, natural disasters, and human-made accidents. It helps to understand how to use urban planning and design strategies to make safer environment. Its application on developing street safe design manuals is also important for enhancing urban spatial performance and environmental quality.

城市安全是当前城市发展备受瞩目的话题之一。街道作为承载了日常交通、社会功能和市民社会生活的城市开放空间，是城市安全治理和城市空间设计的重要对象。课题以“城市街道空间的安全问题”为研究对象，选取北京中心城区为例，通过挖掘多渠道的城市交通安全、防卫安全和防灾安全相关数据，借助遥感技术和GIS等空间分析技术，量化分析城市街道空间特征对城市安全的影响机制，并借助BIM和Agent平台模型构建街道安全空间环境并对街道空间的使用者行为展开模拟评价，以此进一步探索切实有效的提升街道空间安全的城市设计策略。..课题改进以往相关研究在研究对象、尺度和技术上的局限性，构建数字技术集成平台对街道层面的空间影响安全机制展开分析，通过定量空间调查与街道空间安全状况仿真动态模拟，提出切实有效的街道层面应对空间安全的规划设计指引，实现从城市设计维度提升空间安全品质，引导街道规划建设，回应城市安全发展等多重目标。
