With the growing city density and large gatherings happening all over the world, crowd safety has become a new topic. This research discusses how to diagnosis and improve crowd safety in urban public space by analysing a real crowd accident that happened in Shanghai in 2014 using an agent-based simulator. Fact-finding analysis shows that insufficient capacity of the whole area, density difference in bottleneck stairs and lack of separation measurements in front of bottleneck stairs are the main causes of the accident. According to the media query towards the original space plan, we made two alternative plans in the bottleneck area and tested their performances.

Public Space Design

With continuous development of metropolitan, urban population has had a sharp rise in recent few decades, and the following appeared problem is gradual crowd in cities and potential sense of loneliness appearing in individuals in crowds. Urban public space design is very important because it is a main place for people to have social contacts and relaxations. Through analysis and observation of hundreds of urban public space, put forward the proposal to create successful great urban public space some advice.

AbstractWith growing city density and mass gatherings held all over the world in urban spaces, crowd disasters have been happening each year. In considering the avoidance of crowd disasters and the reduction of fatalities, it is important to analyze the efficient spatial layout of the public space in situations of high crowd density. Compared with traditional empirical design methods, computational approaches have better abilities for quantitative analysis and are gradually being adopted in the planning and management of the urban public space. In this paper, we investigated the official documents, publicly available videos, and materials of the Shanghai waterfront crowd disaster which happened on December 31, 2014. Based on the investigation, a detailed site survey was conducted and pedestrian flow data were acquired. To test the influence of different spatial layouts, an agent-based simulator is built, following the ASPFver4.0 (Agent Simulator of Pedestrian Flow) pedestrian walking rules. With the surveyed pedestrian flow data, the original spatial layout of the Shanghai Bund waterfront together with five other comparison scenarios are tested, including both space design and crowd management improvements. In the simulation results, the efficiencies of different space design and crowd management solutions are compared. The results show that even simple crowd control measures such as capacity reserve and more proper route planning will allow for a positive improvement in crowd safety. The results also compare the efficiency of different spatial operations and give general suggestions to the problems urban public space designers should consider in high-density environments.

Any visitor who walked the streets of Paris in the days or weeks following the attacks of January 2015 would definitely have witnessed a particular form of graphic irruption: the dissemination of messages of solidarity and mourning, and the repetition, within this mass of writing, of the formula ‘I am Charlie’. Although the situation was different, the responses to terrorist attacks in January 2015 and the 9/11 aftermath are comparable by the ‘writing event’ (Fraenkel, 2002, 2018) they produced: temporary and atypical dispositifs of writing turned to the public space in order to be read or at least seen by passers-by. This article, structured along chronological lines, traces the evolution of the viral formula over the long term from Twitter to the urban public space. Firstly, the author focuses on the origin and meanings of the statement and formulates several hypotheses that may explain its wide circulation on social networks. Secondly, she analyses the post-attack graffiti based on databases of several private graffiti-cleaning companies in order to highlight the temporary sacralization of illegal writings. The ‘ Je suis Charlie’ phenomenon is interesting in many ways: its staggering, massive diffusion; the apparent unanimity with which it was greeted in the world of politics and the media; and the way it was managed by local authorities.

Chapter 6 looks at the world of official urban planning and placemaking, providing different perspectives on its relationship to DIY urbanism. Through the voices of professional planners, the chapter explores their conflicted opinions on DIY approaches: criticizing their informality and emphasizing the importance of regulations and accountability for everything from basic functionality to social equity, yet sympathetic to do-it-yourselfers’ frustrations and often excited to adopt their tactics, harness their energy, and exploit their cultural value. The chapter then describes how some DIY projects have found pathways to formal adoption and inspired popular “tactical urbanism” and “creative placemaking” approaches to public space design. Many such interventions can result in innovative public spaces with social, environmental, and economic benefits. But the reproduction of an aesthetic experience selectively inspired by a hip grassroots trend and combined with “creative class” values can mark the resulting spaces themselves as elite and exclusionary.
