One of the problems that planners face currently is the difficulty in finding appropriate guidelines for organizing public open spaces in urban areas. This invokes the need to create a system tool to describe and guide the planning of such components of the urban space. This research explores the problems related to the description and the location of public open spaces, and defines a system th...

This study evaluates the diversity, spatial configuration, and pattern of open spaces in urban neighborhoods. Empirical evidence from hedonic modeling reveals that urban residents positively value the varieties of open space but negatively value the diversity within developed land uses. Square shaped plots of open spaces with smooth, as well straight edge are preferred to those of complex and c...
