Comparative analysis of pedestrian volume models
Pedestrian flow distributions can inform planning for walkability and improve understanding of factors that influence pedestrian activity. However, detailed data is rarely available so pedestrian volume models, commonly relying on the Space Syntax framework, are often utilized to predict pedestrian volumes. This study compares the performance and dominant variables of three modelling families – multiple regression analyses, machine learning model…
How far will you go? From empirical findings to formalization of walking route distances
Urban scaling of air pollutants in Israel
Cities have been shown to exhibit empirical scaling behavior where numerous variables of urban performance are allometric, like greenhouse gas emissions. Polluting emissions have negative environmental and health impacts. This paper will elucidate the empirical urban scaling of atmospheric emissions for the Israeli urban system. It has been shown that cities may be environmentally efficient with CO 2 emissions that seem to be sub-linear, so large…
Multiscale accessibility and urban performance
Accessibility is fundamentally thought to be related to functional, economic, and social performances of cities and geographical systems and, therefore, constitutes an essential aspect for spatial planning. Previous studies focused on cities or metropolitan scales, often disregarding their position within regional and national systems, which can greatly affect their performance. Although accessibility at various spatial scales has been examined, …
Probabilistic positioning in mobile phone network and its consequences for the privacy of mobility data
The Study of Walking, Walkability and Wellbeing in Immersive Virtual Environments
Recent approaches in the research on walkable environments and wellbeing go beyond correlational analysis to consider the specific characteristics of individuals and their interaction with the immediate environment. Accordingly, a need has been accentuated for new human-centered methods to improve our understanding of the mechanisms underlying environmental effects on walking and consequently on wellbeing. Immersive virtual environments (IVEs) we…
The spatial organization of accessibility and functional hierarchy
Structural properties of the angular and metric street network's centralities and their implications for movement flows
The street network's angular centralities have been found more suitable than metric centralities for explaining the observed pedestrian and vehicle movement flows in various urban areas. Some studies relate this state to ‘network effects’ – outcomes of the underlying street network structure. However, we have yet to be ascertained how ‘network effects’ work and why angular centralities are superior to metric centralities for modeling movement in …
Why topology matters in predicting human activities
Geographic space is better understood through the topological relationship of the underlying streets (note: entire streets rather than street segments), which enables us to see scaling or fractal or living structure of far more less-connected streets than well-connected ones. It is this underlying scaling structure that makes human activities predictable, albeit in the sense of collective rather than individual human moving behavior. This topolog…
Tolerance, Intergroup Contacts and Municipal‐Spatial Organisation
The paper examines the willingness of Israeli Jews and Arab Palestinians for intergroup contacts during daily activities in diverse functional spaces and spatial organisational contexts within the metropolitan area of Tel‐Aviv, Israel. Semi‐structured interviews were conducted among visitors to public spaces in three mixed Arab‐Jewish areas: a mixed city; two adjacent Jewish and Arab suburban townships; and two relatively distant Jewish and Arab …
Using space syntax and Q-analysis for investigating movement patterns in buildings
In this study, we present the potential of the conjunction between space syntax and Q-analysis methodologies for investigating patterns of movement flows in buildings. This potential is illustrated by an implementation of the two methodologies by comparing between two shopping malls in Israel, which are characterized by distinct spatial configurations. Q-analysis was used to identify the spread of individuals’ movement paths and their conjunction…
Effect of city form and sociospatial divisions on cognitive representation of an urban environment
This study’s goal was to clarify how a city’s form and its internal sociospatial divisions affect cognitive representation of an urban environment. The study was based on an experiment in directional judgment in the city of Tel Aviv; it simultaneously provided conditions for cognitive distortions rooted in the orientation of a city’s form relative to the north–south (N-S) axis together with the socioeconomic and morphological differentiation betw…
Spatial patterns of retail activity and street network structure in new and traditional Israeli cities
The association between spatial patterns of retail activity and the spatial configuration of street networks was examined by means of the space syntax methodology in eight Israeli cities that represent two city types, characterized by different planning approaches and urban growth: (i) new towns, which were established according to a comprehensive city plan and modern planning concepts of “tree-like” hierarchical street networks and “neighborhood…
The Relationship between Spatial Configuration and A rab Minority Residential Patterns in I sraeli Mixed Cities
This paper investigates how city's street network is related to the residential dynamics of the A rab minority's residential pattern in five Israeli A rab‐Jewish mixed cities. Based on the the space syntax methodological framework we analysed the metric and topological access between individual streets. The results obtained show an association between residential pattern changes and the relative access of individual streets to the core area of th…
Geographical Scale of Tolerance in the Urban Area
The paper examines attitudes of mutual tolerance as expressed by the Jewish majority and the Arab minority in Jaffa, a mixed residential area in the city of Tel Aviv. More specifically, it focuses on the willingness of members of each group to share residential locations at different geographical scales (such as: the same housing unit, street, neighborhood, or the city as a whole). The survey’s findings indicate, as expected, that Arabs and Jews …
Density Equalizing Distortion of Large Geographic Point Sets
Visualizing large geo-demographical datasets using pixel-based techniques involves mapping the geospatial dimensions of a data point to screen coordinates and appropriately encoding its statistical value by color. The analysis of such data presents a great challenge. General tasks involve clustering, categorization, and searching for patterns of interest for sociological or economic research. Available visual encodings and screen space limitation…
Distributive Environmental Justice in the City
The socio-economic inferiority of the Arab minority compared to the Jewish majority and the unequal distribution of resources between Jewish and Arab towns in Israel are well known facts. However, so far there has been no evidence establishing whether unequal resource allocation also occurs within mixed Jewish-Arab cities. Based on high-resolution sociodemographic and infrastructure data, this paper examines the access that populations of differi…
