    Abstract : Sustainable urban mobility calls for well-informed design of neighborhoods. Although many studies have been conducted in the field, there is little evidence about the relationships between design elements, urban quality and behavior. Little is also known about residents’ valuation of design and urban quality in this context. READ MORE
