and Åberg, 2008), or on built-up areas or residential streets with 50km/h or 30mph (48km/h) speed limits (e.g. Parker et al., 1992, Elliott et al., 2005). To date, no study has been conducted with respect to breaking the 30km/h speed limit on urban residential streets ...
the problem, here, is formalized as: given a set of grid cells,N, in a county, a set of residential cellsR∈Nwhich are populated by humans, how can we distribute the facilities in grid cellsMto minimize the travel costs (distances) from residential cells to facility cells for all urban...
Public transport accessibility to urban and regional services has been found to relate to various social and economic processes, such as unemployment, transport mode choice, property prices, and public health.

METHODS Measurements of outdoor and indoor daily average and 15 min average PM2.5 mass concentrations were made in 3 urban residential communities in the Minneapolis–St. Paul metropoli- tan area (population 2.6 million with 1.04 million housing units and a population density between ∼365/km2 ...
Carbon emissions from secondary and tertiary industries were inferred by constructing a regression model between nighttime lighting and carbon emissions within urban, rural, industrial, mining and residential land use types. The total carbon emissions of each industry were determined according to the ...
For example, a seasonal investigation of six street canyons in residential Shanghai (China) revealed that in the presence of street trees, the rate of decrease in concentration of PM2.5 with height was much lower compared to tree-less streets [85]. In comparison, another study showed that ...
In recent years, localized downpours have become increasingly frequent in Japan, and inundation risk is growing in urban areas. Local governments, however, are so financially constrained that there is a limit to the speed of progress in ... H Shigemura,H Fujiwara,J Endo,... 被引量: 0发表...
In addition, zoning codes separated residential, commercial, and industrial areas, meaning that people needed to drive to work and to shop. This model makes it difficult to offer public-transit cost-effectively, and large parts of the United States are public-transit deserts. No wonder the ...

We consider only roads with a connecting function, and exclude residential and service roads. In the context of OpenStreetMap we focus on tertiary, secondary, primary, and trunk roads. We obtained for each road segment the number of lanes from OpenStreetMap. We validated each network in terms...
