  • A three-dimensional computational fluid dynamics (CFD) model with the renormalization group (RNG) $k-{\varepsilon}$ turbulence model is used to examine the effects of difference in building height on flow and pollutant dispersion in asymmetric street canyons. Three numerical experiments with different street canyons formed by two isolated buildings are performed. In the experiment with equal building height, a portal vortex is formed in the street canyon and a typical recirculation zone is formed behind the downwind building. In the experiment with the downwind building being higher than the upwind building, the ambient flow comes into the street canyon at the front of the downwind building and incoming flow diverges strongly in the street canyon. Hence, pollutants released therein are strongly dispersed through the lateral sides of the street canyon. In the experiment with the upwind building being higher than the downwind building, a large recirculation zone is formed behind the upwind building, which is disturbed by the downwind building. Pollutants are weakly dispersed from the street canyon and the residue concentration ratio is largest among the three experiments. This study shows that the difference in upwind and downwind building height significantly influences flow and pollutant dispersion in and around the street canyon.

  • This study surveys the degree of residents' satisfaction on the current street space to suggest alternatives for the improvement of the street space design in detached house areas. In the results of the survey, we find the following. First, in the result of analysis on age, residential term, having children or not, income level, and type of house ownership, residents are homogeneous in social and economic characteristics. There are similarity in geographical, locational conditions, neighboring facilities, deterioration of residential house, and the time of residential formation among residential areas. Second, satisfactory determinants of residents on street space according to street types, are maintenance, protection of privacy, and parking space. Third, satisfactory determinants of residents on street hierarchy is the inner circulation road while unsatisfactory one is the inner roads. Fourth, age, residential term and type of house ownership are significant factors influencing residents' satisfaction. Factors influencing satisfaction on street space are also affecting total satisfaction and factors associated with street environment are perceived more important ones than factors associated with street activities. Thus we find the degrees of satisfaction for residents on street type and street hierarchy are different despite that general characteristics of residents are similar. We also find residents consider street noise and maintenance as critical factor among physical factors of street space.
