This study introduces a novel street walkability evaluation framework that integrates both subjective and objective dimensions. By leveraging big data and deep learning technologies, the framework efficiently assesses urban walking environments at both the community and street levels. Its flexibility allows f...
We construct a Voronoi diagram from these photo locations, where each cell of the diagram covers the area closest to that photo location and no other photo location. Sidewalk hazard is taken as the average of the Voronoi cells that the sidewalk edge intersects. The hazard H is scaled such ...
The diagram below shows a half-mile circle around a transit station. If the station were located in a field of grass or on a massive parking lot, the walkable area of the circle would be the circle itself, 100% of the half-mile buffer around the station would be accessible by foot. ...
variable processing, and weighting and aggregation27. Nearly 200 different indicators have been used in urban street walking environment studies28,29. Many focus on community-level elements, with the most typical being the “D” indicators. Robert Cervero et al. proposed the ...
First, the diagram is studied for patterns that emerge, in which certain street segments of higher quality come together to form clear walkable areas. Second, those segments are supplemented by the additional segments that are necessary to connect these different areas together. Finally, that ...
(2002), the network diagram representation of their QFD models has the same linear hierarchy. Thus, in this study an ANP combined QFD will be employed. QFD approach is used as it is a commonly used tool for environmentally conscious design process. Some of those studies in the literature ...
Fig. 1. Cohort consort diagram. 2.4. Outcome variable: Overweight/obesity status At age 14, children were weighed without shoes or outdoor clothing by trained interviewers using Tanita HD305 scales (Tanita UK Ltd, Middlesex, UK). Weights were recorded in kilograms to one decimal place. Heights...
TURNING a Frontage Quality Assessment and Anchors diagram into a Network of Walkability is a three-step process. First, the diagram is studied for patterns that emerge, in which certain street segments of higher quality come together to form clear...

Because of the mutual relationships between variables, we decided to aggregate some variables in several super-indicators, following the inclusion relation and the Hasse diagram procedure [30] (the diagram in Figure 6 represents all the possible combinations of variables which compose the super-...
