Evaluating Crash Risk in Urban Areas Based on Vehicle and Pedestrian Modeling

This article presents a method for investigating the spatial distribution of vehicle and pedestrian traffic crashes relative to the volume of vehicle and pedestrian movement in urban areas. This method consists of two phases. First, vehicle and pedestrian traffic volumes on the street network are modeled using a space syntax configurational analysis of the network, land use data, and observed traffic data. Second, crash prediction models are fitted to the traffic crash data, using negative binomial regression models and based on traffic volume estimates and street segment lengths. The method was applied in two areas in Tel Aviv, Israel, which differ in their morphological and traffic characteristics. The case‐studies illustrated the method's capability in identifying hazardous locations on the network and examining relative crash risks. The analysis shows that an increase in vehicle or pedestrian traffic volume tends to be associated with a decrease in relative crash risk. Moreover, the spatial patterns of relative crash risks are associated with the design characteristics of urban space: areas characterized by dense street networks encourage more walking, and are generally safer for pedestrians, while those with longer street segments encourage more driving, are less safe for pedestrians, but safer for vehicles.     

Towards Planning for a Mobile Society: Mobile and Residential Populations and the Performance of Places

As contemporary society is increasingly structured around highly diverse flows of people, goods, and information, mobile populations will contribute more and more to the economic, environmental and social performance of their destinations. However, planning is largely focused on residential populations and their contribution to the performance of places and hardly pays attention to the implications of people on the move for these places. In this study, we propose an alternative approach towards the assessment of the performance of places by comparing mobile and residential populations. An empirical analysis of the Netherlands National Travel Survey suggests that planning could profit by analysing mobile populations and exploring the desirability and feasibility of influencing their decisions.     

Home away from home: meanings of the American truck stop

This paper explores the place attachments of long-haul truck drivers to the truck stop. The feelings and ideas truckers have about truck stops are based upon the function these businesses play in the truckers' mobile lifestyle and the social interactions that are performed within those spaces. Drivers' relationships to these stops also illustrate that modernity and the prevalence of homogenized places do not result in placelessness because feelings and perceptions about these places are based upon the role these businesses play in the everyday tasks of long-haul drivers.     

Applying Local Indicators of Spatial Association to Analyze Longitudinal Data: The Absolute Perspective

Local Indicators of Spatial Association (LISA) are a class of spatial statistical methods that have been widely applied in various scientific fields. When applying LISA to make longitudinal comparisons of spatial data, a common way is to run LISA analysis at each time point, then compare the results to infer the distributional dynamics of spatial processes. Given that LISA hinges on the global mean value that often varies across time, the LISA result generated at time T_i reflects the spatial patterns strictly with respect to T_i. Therefore, the typical comparative cross-sectional analysis with LISA can only characterize the relative distributional dynamics. However, the relative perspective alone is inadequate to comprehend the full picture, as the patterns are not directly associated with the changes of the spatial process’s intensity. We argue that it is important to obtain the absolute distribution dynamics to complement the relative perspective, especially for tracking how spatial processes evolve across time at the local level. We develop a solution that modifies the significance test when implementing LISA analysis of longitudinal data to reveal and visualize the absolute distribution dynamics. Experiments were conducted with Mongolian livestock data and Rwanda population data.     

Sense and the city: exploring the embodied geographies of urban walking

Within UK pedestrian policy, walking is promoted as a sustainable mode of transport that benefits both the body and mind. However, much policy discussion assumes all walking to be the same and a largely self-evident means of transport, whilst many academic engagements with walking are highly abstract theorisations that lack any systematic empirical exploration of actual pedestrian practices. As such, there is little that unpacks the experiences of those who navigate, negotiate, and traverse the city streets in their day-to-day lives. In contrast, this paper aims to situate and understand the practice of everyday walking in the unfolding experiences of urban pedestrians. Walking is positioned and understood as a socio-technical assemblage that enables specific attention to be drawn to the embodied, material and technological relations and their significance for engaging with everyday urban movements on foot. The analysis draws upon in-depth interview and walking photo diary data from participants in the inner London boroughs of Islington and Hackney. Particular analytic attention to the different styles and conventions of urban walking and how these are intimately linked to bodily senses and the materiality of the city provides an opportunity for creating an increased engagement between urban and pedestrian policy and urban and social theory.

Gendered mobilities in the making: moving from a pedestrian to vehicular mobility landscape in Shimshal,Pakistan

Although feminist geographers understand gender and mobility as mutually constitutive social processes, few studies explain how gender relations are constituted in particular mobility contexts, and how and why they shape mobility patterns in specific socio-spatial circumstances. We address these questions in an analysis of gendered mobilities in Shimshal, Pakistan, which until recently have taken shape in the context of a pedestrian mobility regime. The gender and mobility relationship has transformed as vehicular mobilities have replaced pedestrian mobilities with the construction of the Shimshal road. To demonstrate empirically the co-constitution of gender and mobility, we analyze aspects of socio-spatial context that have shaped gendered pedestrian mobilities, followed by those associated with the new vehicular mobility regime that are modifying gender relations in Shimshal. Shifting gender relations reshape corporeal mobility patterns. Road infrastructure has enhanced men’s and youth’s outbound travel as wage earners and students, respectively. These mobilities have reshaped women’s capacity to move, constraining their mobility beyond the village. As prosperity becomes contingent on outbound movement, men’s and youths’ social horizons and mobilities are expanding, while women’s compromised access to mobility as a social resource produces new mobility hierarchies and gendered exclusions.     

A Method For Calculating The Requirements For Mobile Public Services Under Various Geographical Conditions

A formula is developed for computing the requirements for mobile service units, such as traveling stores, repair shops, and clubs, in various types of rural settlement patterns. The formula takes into account the character of the service rendered, the number and density of the places to be served, the state of the roads, climatic conditions, and other factors. Mobile-unit requirements are found to increase with a decline in the average population, in places to be served, and in density of places. The requirements are highest in remote range-grazing lands in the southern Soviet Union.     

IDENTITIES AND URBAN SOCIAL SPACES IN LITTLE TOKYO,LOS ANGELES: JAPANESE AMERICANS IN TWO ETHNO‐SPIRITUAL COMMUNITIES

Ethnic identities are expressed and articulated in particular places. These mutable identities are crucial sources of meaning in the lives of social actors. This article seeks to elucidate just how the contexts of specific institutions in an urban enclave will impact upon patterns of conflict and cooperation among different subgroups practising two religious traditions. Historical discourses of ethnic community and ‘race’, shifts in migration patterns and the changing nature of the Little Tokyo enclave provide the formative patterns of social spaces, in which ethnic actors seek to create lives of spiritual and material meaning and security. Barth's concept of the social organization of cultural difference encourages analysis of ethnic identities as a dynamic and mutable enterprise. Because the maintenance of boundaries is crucial to identities, the manner in which a group seeks to maintain difference is intermeshed with the social terrain of particular places. Through qualitative methods of semi‐structured and informal interviews and participant observations, this project engages Japanese American identities within the context of two religious communities in an urban enclave. Fieldwork was conducted in two institutions, a Protestant church and a Buddhist temple, with the aim of exploring how Japanese American identities are expressed and (re)negotiated within different ethno‐spiritual communities. Such communities are fundamental to the expression of ethnic identities, and to the emotional lives of worshippers, particularly seniors and new immigrants.     

MAKING PLACES MATTER IN EARLY NEOLITHIC DORSET

Summary.   By exploring an Early Neolithic site this paper demonstrates how landscapes are constituted from connected places and, in turn, how places are constituted by materials. The paper aims to develop an approach that acknowledges the role of memory and emotion within this, and posits that these factors are crucial to how senses of place and community were formed in this period. By considering memory and emotion the paper demonstrates their centrality to any human experience of landscape.     

A Methodology for Assessing the Heritage of Planned Urban Environments: An Australian Study of National Heritage Values

Although urban planning has made strategic and notable contributions to the production of the built environment, these are under‐represented in heritage discourse. Planned environments deserve more attention as a particular class of place because a better understanding of planning and planning excellence can inform best heritage practice. A stepwise methodology for the heritage assessment of planned environments is presented. It is drawn from an Australian study concerned with the identification of places of possible national heritage significance. The approach is constructed around the identification of historical themes (for the categorisation and benchmarking of places based on historical research), indicators (pertaining to the nature of significance in planning terms) and thresholds (pertaining to the degree of significance). The analytical approach is capable of adaptation to diverse settings in which the heritage contribution of planning may be recognised.     

Seasonal weather sensitivity,temperature thresholds,and climate change impacts for park visitation

Historical park visitation and weather data, taken at the daily time scale from 2000 to 2009 for Pinery Provincial Park in southern Ontario (Canada), were analysed as an objective measure of the weather sensitivity, temperature thresholds, and potential impacts of projected climate change for park visitation. Three seasonal weather-visitation models were constructed using multivariable linear regression (peak, shoulder, off-season). To account for both natural and institutional seasonality, the weather-visitation models included both climatic (temperature, precipitation) and social (weekends, holidays) variables, which demonstrated equably comparable effects on visitation across the three models. Critical temperature thresholds were identified for each season using one-way analysis of variance to determine the range of temperatures within which the threshold was evident; the specific degree of temperature associated with the threshold was identified within the seasonal regression models. Temperatures over 33 °C during the peak season and over 29 °C during the shoulder season indicated critical thresholds at which point conditions that were ‘too hot’ for some caused a decline in visitation. Furthermore, temperatures below 11 °C indicated another critical threshold, where conditions were ‘too cold’ for most and therefore park visitation was less sensitive to temperature variability below this threshold. A partial sensitivity analysis for the impact of a warmer, wetter climate on park visitation was conducted, illustrating the effect of a 1 °C to 5 °C warming in maximum temperatures, coupled with a 5% to 15% increase in total precipitation. In response to projected climate change, the weather-visitation models suggested that for each additional degree of warming experienced, despite the negative effects of increasing precipitation and more frequent heat extremes, annual park visitation could increase by 3.1%, annually. The projected increase in park visitation as a result of rising temperatures was mainly associated with shoulder season visitation, with only minor increases in peak season visitation.

Place, networks, space: theorising the geographies of social movements

This essay examines how geography affects the different types of networks underlying social movements. The principal argument of the paper is that networks forged in particular places and at great distances play distinctive yet complementary functions in broad-based social movements. Not only does the articulation of these different types of networks result in complementary roles, but it also introduces key relational dynamics affecting the stability of the entire social movement. The purpose of the paper is therefore threefold: to provide a conceptual framework for interpreting the complex geographies of contemporary social movement networks, to stress the contributions of place-based relations in social movements and to assess how activist places connect to form 'social movement space'.     

Getting comfortable to feel at home: clothing practices of black muslim women in Britain

This article explores the role of comfort as an affective encounter across bodies, objects (namely clothing) and spaces. I focus on how bodies that are marked as strange and a source of society’s discomfort negotiate this positioning through the presentation of one’s body. What does it mean for these bodies to be comfortable or uncomfortable? This question is answered through work done with Black Muslim women in Britain. By exploring how comfort is felt in relation to racially marked bodies, this article develops work on emotional geographies. Comfort is understood as both an emotional product and process that changes as bodies move across different spaces. In noting this movement, I also explore how boundaries around the body (enacted through e.g. the multi-dimensional hijab) presents a particular form of territorialisation that facilitates comfort as we present our bodies across different spaces. These boundaries can be both a source of comfort and discomfort through their positioning as deviant from social norms. In understanding the different roles of boundaries, I explore the social processes that construct comfort (or discomfort) as we move through different spaces. This is intertwined with furthering work on Muslim geographies by challenging the overwhelming focus placed on ‘public’ facing garments like the headscarf and abaya. Such a focus limits an understanding of the fluidity of Black Muslim women’s identities, and how these changes in our clothing practices affect and are affected by the relationships built across spaces.     

Toward a Cultural Landscape Atlas: Representing all the Landscape as Cultural

Many government and non‐statutory registers utilise point datasets to represent cultural heritage places. An effect of this approach is to emphasise that cultural heritage comprises a series of spatially discrete material remains or ‘sites’, suggesting discrete locations which are somehow disconnected from their broader historical and landscape contexts. We advocate an alternative in which spatial representation of heritage is set within a cultural landscape framework, acknowledging that all parts of the landscape have inter‐connected cultural histories, associations and meanings resulting from long‐term and ongoing human–environmental interactions. Results from a collaborative cultural heritage research project undertaken at Culgoa National Park in Australia demonstrate the advantage of this approach. The mapping products produced by the work comprise an interactive electronic DVD Atlas and hard copy maps. Both focus on meeting the management needs of field‐based park staff.     

Quantifying Animal Trajectories Using Spatial Aggregation and Sequence Analysis: A Case Study of Differentiating Trajectories of Multiple Species

The increasing availability of telemetry data with high spatial and temporal resolution promises to greatly advance scientific understandings of the movement patterns of individual organisms across space and time. The amount of data provided by such methods, however, can be challenging to analyze and interpret. In this study, we present a new approach for analyzing animal movements that aggregates telemetry locations into spatial clusters and extracts the information from sequences formed by individuals passing through these spatial clusters. We applied this integrated approach of spatial aggregation and sequence analysis to quantify and compare trajectories of cattle (Bos taurus), mule deer (Odocoileus hemionus), and elk (Cervus elaphus) tracked by automated telemetry at the Starkey Experimental Forest and Range in northeastern Oregon, USA. Our approach effectively differentiated movement patterns of the three species. It provides a useful mean of quantifying movement patterns of species in a landscape.     

The Siting of Medieval Castles and the Influence of Ancient Places

THIS PAPER EXAMINES the ways in which the siting of castles in England was influenced by the remains of monuments and landscapes from the prehistoric and Romano-British periods. It explores the character, distribution and scale of ancient monument reuse as evidenced through the archaeological and documentary record, in an attempt to discern patterns in peoples’ responses to monuments from the ancient past. It considers the ways in which these places were perceived by both the ruling elite and the local community: exploring how inherited landscapes were used in castle building to structure concepts of belonging, constituted through memory and genealogy. The conclusion is that ancient places were reused by castle builders from the 11th to the 14th century as part of an evolving narrative aimed at enhancing rights to people, place and power.     

Playing with fear: parkour and the mobility of emotion

This article engages debates on emotional geography and non-representational theory by considering fear as a distinctly mobile engagement with our environment. Parkour, or freerunning, has exploded into public consciousness through commercial media representations and films. It is depicted as a spectacular urban sport that either can or cannot be done. Through ethnographic research with groups of parkour practitioners I consider what has been excluded from these representations: the emotions involved in trying, experimenting, and gradually learning to be in places differently. In parkour places are ‘done’ or mobilised in tentative, unsure, ungainly and unfinished ways which can be characterised by a kind of play with architecture. I argue that this play is contingent upon an array of fears, which, rather than being entirely negative, are an important way in which practitioners engage with place. Here fears can manifest differently, not only restricting mobility, but in some cases encouraging imaginative and playful forms of movement.
