“…The crude open space consists of many types of open spaces, and specific open-space ratios are defined. Examples include green open-space ratio [24,25], green coverage ratio [26,27], public open-space ratio [28,29], space ratio [30], park ratio [31,32], water surface ratio [33,34], river ratio [35,36], and road ratio [37,38]. These open-space ratio functions are easily computed using the crude open-space ratio functions formulated in the previous section.…”

An open-space ratio is often used as a first basic metric to examine the distribution of open space in urbanized areas. Originally, the open-space ratio was defined as the ratio of the area of open space (unbuilt area) to the area of its building site. In recent years, residents have become more concerned with the open-space ratios in the broader neighborhoods of their individual buildings than with their own building sites. To address this concern, this paper proposes a method for dealing with the open-space ratio in the variable -meter buffer zone around each building, called the open-space ratio function, and implements it using standard GIS operators. The function and its implemented analytical tool can answer the following questions. First, this function shows how the ratio varies with respect to the bandwidth to discuss the modifiable area unit problem. Second, as the ratio changes, the function shows in which bandwidth zone the ratio is the highest, indicating the best open-space environment zone. Third, in the pairwise comparison for housing selection, the function shows in which bandwidth zone a specific house is better than another. Fourth, the function shows in which bandwidth zone the variance among all buildings in a region is the greatest. Fifth, in this zone, buildings are clustered in terms of open-space ratio. The resulting clusters are the most distinct. Sixth, to examine the open-space ratio around a clump of buildings (such as a housing complex), the function shows how to obtain clumps. Seventh, it is shown how the open-space function provides a wide range of applicability without changing the mathematical formulation. Finally, this paper shows how to implement the function in a simple computational method using operators and a processing modeler provided by the standard GIS without additional software.

“…Generally, the indicators used to describe street scale include the street length, total street width, vehicle lanes' width, pedestrian sidewalk width, and ratio of width to height. We select one index of green coverage rate for street greening [51]. The street-facing interface is the vertical interface of street space and also an important part of the street.…”

Against the background of the aging trend in China, construction and regeneration strategies for an aging-friendly built environment are becoming common, led by urban governments, and public street spaces are the focus of these strategies. Exploring such planning and design strategies can help to improve the social welfare of the aging population and meet their diverse needs. Thus, this paper, through analyzing the determinants of the elderly’s needs, examines the relationship between spatial perception and street form, using Shanghai, in China, as a case study. This study contributes to the current literature in two ways: first, it constitutes the first attempt to build a needs hierarchy for aging people in a Chinese developed city; second, our statistical analysis involves large-scale population surveys, which helps us to comprehensively and deeply understand the impact of detailed street forms on the elderly’s various spatial perceptions. Our results indicate that the renovation of street space in different areas of cities can be improved by the control of street form, to meet the diverse needs of the local aging group.

“…This is because albedo plays an important role in UHI and may be controlled more easily than the other factors and because the ratio of green coverage, which relates to impervious urban surfaces, has already been discussed in a previous study (Sotoma et al, 2003). Researchers have dealt with albedo from various perspectives (Aida,1982;Brest et al, 1987;Kyakuno et al, 2002;Izumi et al, 2000;Nakagawa et al, 1992;Nakagawa et al, 1995;Nakagawa et al, 1996;Small et al, 2000;Zhao et al, 2000).…”

Urban surface albedo, which is one of the important factors of the urban heat island phenomenon, was used to evaluate urban land use regulations. Broadband albedo at the surface level of Sakai City, Japan, was calculated, and effects of land use regulations and actual land use were estimated using satellite remote sensing data, a land use regulation map and detailed digital information expressing actual land use. Land use regulations defi ne land use, maximum building coverage ratios and maximum fl oor area ratios, which relate the heights of buildings to the areas of their sites. These factors have effects upon broadband albedo and each narrowband albedo corresponding to wavelengths observed by Landsat ETM+. Albedo values differed according to land use regulation zones. The combination of land use regulation and actual land use is also meaningful in grasping urban surface albedo. But this relationship may provide only slight insight into the urban heat island phenomenon.
