This contribution examines the so-called ZAD of Notre-Dame-des-Landes, a municipality near the city of Nantes in the Western French department Loire-Atlantique. Officially, the abbreviation ZAD stands for the term “designated development area”, zone d’aménagement différé. For decades the site was intended to be the building zone of a large airport project. The opponents of this infrastructure project reinterpreted the abbreviation ZAD: in their understanding and common parlance it means zone to defend- zone à défendre. Within the scope of large-scale protest against the airport project the site had been occupied since 2009. The article examines whether and to what extent the occupied ZAD of Notre-Dame-des-Landes could be described as a socially critical threshold space. In this context it seeks to explore the socio-critical potential and its spatial components with reference to geographical characteristics, location and ideas related aspects as well as action-related factors. The contribution refers to the situation in the first half of the year 2015, before the official abandonment of the airport project and the evacuation of the site. Due to the high dynamic of the developments within the ZAD the findings discussed in this article should be regarded as a “snapshot”.

The City

Urban society is undergoing as profound a spatial transformation as that associated with the emergence of the industrial city two centuries ago. To describe and measure this transition, we introduce a new theory based on the concept that large-scale, complex systems composed of many interacting elements, show a surprising degree of resilience to change, holding themselves at critical levels for long periods until conditions emerge which move the system, often abruptly, to a new threshold. This theory is called ‘self-organized criticality’; it is consistent with systems in which global patterns emerge from local action which is the hallmark of self-organization, and it is consistent with developments in system dynamics and their morphology which find expression in fractal geometry and weak chaos theory. We illustrate the theory using a unique space–time series of urban development for Buffalo, Western New York, which contains the locations of over one quarter of a million sites coded by their year of construction and dating back to 1773, some 60 years before the city began to develop. We measure the emergence and growth of the city using urban density functions from which measures of fractal dimension are used to construct growth paths of the way the city has grown to fill its region. These phase portraits suggest the existence of transitions between the frontier, the settled agricultural region, the centralized industrial city and the decentralized postindustrial city, and our analysis reveals that Buffalo has maintained itself at a critical threshold since the emergence of the automobile city some 70 years ago. Our implied speculation is: how long will this kind of urban form be maintained in the face of seemingly unstoppable technological change?

Since the late 20th century major, European cities have exhibited large projects driven by neoliberal urban planning policies whose aim is to enhance their position on the global market. By locating these projects in central city areas, they also heighten and reinforce their privileged situation within the city as a whole, thus contributing to deepening the centre–periphery rift. The starting point for this study is the significance and scope of large projects in metropolitan cities’ urban planning agendas since the final decade of the 20th century. The aim of this article is to demonstrate the correlation between the various opposing conservative and progressive urban policies, and the projects put forward, for the city of Madrid. A study of documentary sources and the strategies deployed by public and private agents are interpreted in the light of a process during which the city has had a succession of alternating governments defending opposing urban development models. This analysis allows us to conclude that the predominant large-scale projects proposed under conservative policies have contributed to deepening the centre–periphery rift appreciated in the city.

Providing citizens with the ability to move around in an accessible way is a requirement for all cities today. However, modeling city infrastructures so that accessible routes can be computed is a challenge because it involves collecting information from multiple, large-scale and heterogeneous data sources. In this paper, we propose and validate the architecture of an information system that creates an accessibility data model for cities by ingesting data from different types of sources and provides an application that can be used by people with different abilities to compute accessible routes. The article describes the processes that allow building a network of pedestrian infrastructures from the OpenStreetMap information (i.e., sidewalks and pedestrian crossings), improving the network with information extracted obtained from mobile-sensed LiDAR data (i.e., ramps, steps, and pedestrian crossings), detecting obstacles using volunteered information collected from the hardware sensors of the mobile devices of the citizens (i.e., ramps and steps), and detecting accessibility problems with software sensors in social networks (i.e., Twitter). The information system is validated through its application in a case study in the city of Vigo (Spain).

Knowledge of the sunshine requirements of landscape plants is important information for the adaptive selection and configuration of plants for urban greening, and is also a basic attribute of plant databases. In the existing studies, the light compensation point (LCP) and light saturation point (LSP) have been commonly used to indicate the shade tolerance for a specific plant; however, these values are difficult to adopt in practice because the landscape architect does not always know what range of solar radiation is the best for maintaining plant health, i.e., normal growth and reproduction. In this paper, to bridge the gap, we present a novel digital framework to predict the sunshine requirements of landscape plants. First, the research introduces the proposed framework, which is composed of a black-box model, solar radiation simulation, and a health standard system for plants. Then, the data fitting between solar radiation and plant growth response is used to obtain the value of solar radiation at different health levels. Finally, we adopt the LI-6400XT Portable Photosynthetic System (Li-Cor Inc., Lincoln, NE, USA) to verify the stability and accuracy of the digital framework through 15 landscape plant species of a residential area in the city of Wuhan, China, and also compared and analyzed the results of other researchers on the same plant species. The results show that the digital framework can robustly obtain the values of the healthy, sub-healthy, and unhealthy levels for the 15 landscape plant species. The purpose of this study is to provide an efficient forecasting tool for large-scale surveys of plant sunshine requirements. The proposed framework will be beneficial for the adaptive selection and configuration of urban plants and will facilitate the construction of landscape plant databases in future studies.

Abstract In this paper, we apply flexible data-driven analysis methods on large-scale mass transit data to identify areas for improvement in the engineering and operation of urban rail systems. Specifically, we use data from automated fare collection (AFC) and automated vehicle location (AVL) systems to obtain a more precise characterisation of the drivers of journey time variance on the London Underground, and thus an improved understanding of delay. Total journey times are decomposed via a probabilistic assignment algorithm, and semiparametric regression is undertaken to disentangle the effects of passenger-specific travel characteristics from network-related factors. For total journey times, we find that network characteristics, primarily train speeds and headways, represent the majority of journey time variance. However, within the typically twice as onerous access and egress time components, passenger-level heterogeneity is more influential. On average, we find that intra-passenger heterogeneity represents 6% and 19% of variance in access and egress times, respectively, and that inter-passenger effects have a similar or greater degree of influence than static network characteristics. The analysis shows that while network-specific characteristics are the primary drivers of journey time variance in absolute terms, a nontrivial proportion of passenger-perceived variance would be influenced by passenger-specific characteristics. The findings have potential applications related to improving the understanding of passenger movements within stations, for example, the analysis can be used to assess the relative way-finding complexity of stations, which can in turn guide transit operators in the targeting of potential interventions.

This article uses the materials of the Drezdensha affair, a large-scale investigation of “indecency” in St. Petersburg in 1750, to explore unofficial sociability among the Imperial elite, and to map out the institutional, social, and economic dimensions of the post-Petrine “sexual underworld.” Sociability and, ultimately, the public sphere in eighteenth century Russia are usually associated with loftier practices, with joining the ranks of the reading public, reflecting on the public good, and generally, becoming more civil and polite. Yet, it is the privately-run, commercially-oriented, and sexually-charged “parties” at the focus of this article that arguably served as a “training ground” for developing the habits of sociability. The world of these “parties” provides a missing link between the debauchery and carousing of Peter I's era and the more polite formats of associational life in the late eighteenth century, as well as the historical context for reflections on morality, sexual licentiousness, foppery, and the excesses of “westernization.”

<p>Should a bridge always be functional and accessible? Should it always fulfil its purpose? This seemingly self- evident question is a key question in footbridge design that is oriented towards creating experiences.</p><p>Footbridges are able to successfully enriches our experience of a certain context or landscape, it cannot be functional all the time, under all environmental conditions, weather and seasons. A good example is the Zalige bridge designed as part of the Room for the River, a large-scale national program for inland flood- protection in the Netherlands. Build upon the floodplains within a newly created river-park by the city of Nijmegen, the Zalige bridge’s curved shape stands in direct relationship to the fluctuating water levels of the river. When water levels rise, the bridge partially submerges, becoming only accessible through steppingstones. At peak heights, the bridge disappears completely, becoming a metaphor for our relationship to the water.</p><p>“Building a bridge that fails to fulfil its sole purpose of containing the water; this can only be pulled off in the Netherlands.” – jury Dutch Design Awards about the Zalige bridge.</p><p>The loss of functionality is directly related to the creation of an experience. When the water levels rose in January 2018, the bridge became the prime location to experience the changing landscape. It shows that engineering a bridge is not solely focussed on the most efficient engineering, but for the purpose it fulfils as for society. For most pedestrian bridges where the perception of the user is on a different level as for a highway bridge, functionality provides more than just cost driven or efficiency driven parameters. It is more related to the added value for the community. When design not solemnly derives from the sheer taste and predilection of the designer but is based on the user’s experience, it generates a durable relation with a feeling of ownership of its users. The key is to create this experience in an elegant and natural way and not forced or dictated. It should be people's own unique discovery and should not be imposed.</p>
