Network connectivity refers to the quality of the connections that link every point in a community to every other point in a community. It is determined by the structure of the street network in terms of the pattern of streets and intersections, but the quality of those connections varies depending on the structure of the network (Handy, et al. 2003). Between any two points, a network might pro...

The success or failure of the street network depends on its reliability. In this article, using resilience analysis, the author studies how the shape and appearance of street networks in self-organised and top-down planned cities influences urban transport. Considering London and Beijing as proxies for self-organised and top-down planned cities, the structural properties of London and Beijing n...

This study tested the representativeness of four street segment sampling protocols using the Pedestrian Environment Data Scan (PEDS) in eleven neighborhoods surrounding public housing developments in Houston, TX. The following four street segment sampling protocols were used (1) all segments, both residential and arterial, contained within the 400 meter radius buffer from the center point of th...

Measures of network structural integrity useful in the analysis and synthesis of power systems are discussed. Signal flow methodology is applied to derive an expression for the paths between sources and sinks in a power network. Connectivity and reach ability properties of the network are obtained using the minors of a modified connectivity matrix. Node-connectivity, branch connectivity and mix...

Our paper and presentation will describe how we used ArcGIS to manage multiple sources data and to derive quantitative measures of neighborhood level characteristics for six study sites around the US. Some of the neighborhood characteristics include proximity to recreational facilities, street connectivity, population density, crime, mass transit, neighborhood SES, neighborhood terrain, and lan...

Urban form is defined as the physical characteristics that make built-up areas, including shape, size, density, and configuration of settlements. Many researchers urban forms by morphological attributes areas at all scales, from localized to broader scales. Generally speaking, street network most significant attribute in understanding morphology, it affects determines form: hierarchy, ...etc. T...

Abstract Nature-based solutions (NBS) are recognised as a means to address challenges such heatwaves, flooding and biodiversity loss. Delivering these benefits at scale will require large areas of scarce urban land be converted into green space. Here we show an approach by which cities can make substantial progress towards their sustainability targets using NBS, converting redundant street park...
