Evolution in layout design is discussed in terms of the 4Ds of urban form factors: density, diversity, design (street connectivity and intersection density) and destination accessibility (proximity).
Using data from the National Longitudinal Study of Adolescent Health (Wave I; 1994 95), we compared associations between moderate-vigorous PA (MVPA) and PA facility counts and street connectivity measures (intersection density and link:node ratio) within 1, 3, 5, and 8.05 km of each respondent's residence (Euclidean neighborhood buffers).
We used a database of over one million water bodies in 100 cities across the conterminous United States to compare the size distributions, connectivity (as intersection with surface flow lines), and shape (as measured by shoreline development factor) of water bodies in different land cover classes.
Briefly, the walkability index captured four measures of neighborhood walkability (residential density, retail floor space to land area ratio, land use mix, and street connectivity or intersection density) within a 1-km road network distance around a postal code centroid.
Therefore, in this paper, we propose a connectivity-aware intersection-based routing (CAIR) protocol for urban VANETs.
In LSGR, the forwarding node chooses the intermediate node with better quality link in straight road and chooses the road segment with higher connectivity in the intersections.
The proposed tracking scheme consists of four stages: (a) segment tracing, (b) trace intersection, (c) connectivity graph construction, and (d) subgraph extraction.
We therefore delineated such consistent connectivity by computing the intersection of the (cluster-level FWE corrected) connectivity maps from the two analyses.
Traditionally, transportation experts paid more attention to traffic engineering-related issues, such as traffic configuration, the number of intersections and connectivity of local roads, highways, railways and other transportation infrastructure [19].
The street connectivity composite scale based on intersection density, average block length and connected node ratio in a 1 km radius around each school has been used in similar studies 8 17 but was never validated.
