Abstract

Accurately revealing the temporal and spatial laws of urban public safety incidents can provide a scientific basis for the construction of urban public safety. Telephone complaints are an important way for residents to perceive urban public safety based on objective reality. This paper uses the 12,345 citizen complaint hotline data in Beijing to explore the temporal and spatial distribution patterns and aggregation characteristics of urban public safety within a day by Emerging HotSpot Analysis. And analyzes the safety space classification based on the characteristic patterns. The results show that: ①The curve of complaints about urban public safety incidents in Beijing is obvious “double peaks” characteristics within one day, at 10:00 a.m. and 3:00 p.m. respectively; ②The occurrence of urban public safety incidents occurs from scratch, from small to large, from large to small, and gradually disappearing within one day; ③The complaints of urban public safety show significant aggregation characteristics in each time period, and the degree of aggregation changes with time; ④ The main manifestations are scattered hot spots and oscillating hot spots. The research conclusions are expected to provide new ideas for urban public safety research and enrich social perception research based on complaint data.

居民投诉下城市公共安全的时空特征：来自北京市12345数据的证据

准确揭示城市公共安全事件的时空规律，可以为城市公共安全建设提供科学依据。电话投诉是居民基于客观现实感知城市公共安全的重要途径。本文利用北京市12345条市民投诉热线数据，通过新兴热点分析（Emerging HotSpot Analysis），探讨一天内城市公共安全事件的时空分布规律和聚集特征。并根据特征规律进行安全空间分类分析。结果表明北京市城市公共安全事件投诉曲线在一天内具有明显的 "双峰 "特征，分别出现在上午 10 点和下午 3 点分别为上午 10 点和下午 3 点；②城市公共安全事件的发生从无到有、从小到大、从大到小，并在一天内逐渐消失；③城市公共安全投诉在各时间段呈现明显的聚集性特征，且聚集程度随时间变化而变化；④主要表现为热点分散和热点振荡。研究结论有望为城市公共安全研究提供新思路，丰富基于投诉数据的社会感知研究。

期刊介绍： Journal of Urban Management (JUM) is the Official Journal of Zhejiang University and the Chinese Association of Urban Management, an international, peer-reviewed open access journal covering planning, administering, regulating, and governing urban complexity. JUM has its two-fold aims set to integrate the studies across fields in urban planning and management, as well as to provide a more holistic perspective on problem solving. 1) Explore innovative management skills for taming thorny problems that arise with global urbanization 2) Provide a platform to deal with urban affairs whose solutions must be looked at from an interdisciplinary perspective.
