Cognitive Distance Affected by Urban Vegetation : Evaluation at Perspective Knowledge Level＜論文＞

This research was aimed to investigate how the presence of tree lines in urban streets could affect the perspective distance judgment and to establish a set of vegetation design parameters that could affect such judgment. By varying the vegetation design parameters growth stage, spacing, tree species and canopy condition, the investigation evaluated the corresponding evaluation for the subjective distance. Results showed that subjects overestimated the distances in the vegetated settings in comparison to the nonvegetated settings. The spacing of trees was found to be affective on cognitive distance judgment
