摘要

本研究之目的在於探討市區幹道路型及植栽配置位置對於用路人景觀偏好之影響。藉由電腦動畫之輔助，本研究模擬各種可能配置方案於行進間之視覺效果，並設定不同視覺角度進行調查。研究方法以多向度度量法為主，並輔以迴歸及集群分析，進而界定用路人之景觀偏好認知特性。研究結果顯示，駕駛者之偏好特性為「美觀度」、「植栽分布數量」、「車道與人行道間有植栽」以及「與植栽最近距離」；行人之偏好特性則為「安全度」、「分隔帶與人行道均有植栽」、「車道與人行道间有植栽」及「舒適度」。分隔型式則不會影響用路人之景觀偏好。考量使用者之安全性感受較美觀度更為重要，建議植栽配置應側重行人之需求，人行道上之植栽帶應加強其連續性，而分隔帶除應有植栽外，並應留設行人穿越時之庇護空間。本研究成果除可供路型規劃設計之參考外，其於資料調查與分析方法之改良，亦可供後續研究之參考。

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.
