This paper presents the results from the 'Streetscapes' study. The study investigated innovative ways of increasing participation in urban design, namely through the use of the choice experiment methodology. The research combined economic valuation with urban design and computer visualisation. The Castlegate area of Aberdeen, Scotland was used as the case study area. Choice experiments allow the values which people place on individual attributes, as well as the quality and quantity of those attributes, to be estimated. Furthermore, values can be placed on different packages of attributes, such as the locations of trees and furniture within the case study area, and street lights with or without hanging plant baskets. In this study, the use of choice experiments to value streetscapes was original in two respects. First, the choice sets presented to respondents were image rather than text based, and second, the study was conducted via the Internet.
