Popular perception and preference for aesthetic and ecological attributes on tree-lined street composition

Abstract

The planning of tree-lined street is a complex process that involves environmental aspects, urban development and popular preference. This research aimed to analyze popular perception and preference for aesthetic and ecological attributes in the tree-lined street composition. Data were obtained by an electronic poll that contained different drawings and ways of tree-lined street composition, as well as attributes of forest species like size and flowering. Data were compared by Mann-Whitney test (options given in pairs), by Kruskal-Wallis test (more than two options) and by multiple canonical correspondence analysis for perceptual mapping. For the transversal view there was no significant difference between votes given to the options presented. In relation to longitudinal view people preferred those with more diversity of species. There was significant difference between votes given to the ways of composition, especially the one with species distributed one by one. In relation to species characteristics there was significant difference between votes given to the options with predominance of preference for medium sized species and those that have yellow flowering.
