　　The objective of this study is to examine road users’ preference for tree allocation for different configurations of urban arterials. A survey was conducted with the assistance of computer animation to simulate visions of road users. Preferences of both drivers and pedestrians were investigated. Methods of Regression Analysis, Cluster Analysis, and Multidimensional Scaling were used to analyze surveyed data. The results showed that drivers’ preference was affected by aesthetics of street, the number of tree allocation, trees planted on left-side of sidewalk and the shortest distance to trees. As for pedestrians, their cognition features were safety, tree planted on division strip and sidewalk, tree planted on left-side of sidewalk, and comfortability. The results also showed that both of drivers’ and pedestrians’ preferences were not affected by divided type of urban arterials. This study provided important information on designing urban arterial streets. It also presented a new approach for preference survey and data analysis in the field of transportation.
