近年來由於休閒時間增加、所得提高、交通便利、生活壓力大等因素，使得人們對於休閒遊憩活動之需求日漸增加。而隨著永續發展思潮興起，自行車因兼具人本、綠色（低汙染、低能耗）、低使用成本、休閒、與樂活概念等特性，故越來越多臺灣民眾選擇作為通勤及假日休閒的運輸工具。目前台北縣市共設置總長約210公里的河濱自行車道，其中行經「淡水金色水岸」，總長約12公里的「金色水岸自行車道」，為目前臺北地區最受歡迎的自行車道路線之一。而由於使用者之願付價格係表示使用該項設施所帶來之經濟效益，因此，為瞭解淡水金色水岸自行車道對於使用者之效益，本研究乃利用Tobit分析模式探討自行車道使用者之願付價格及其影響因素，並分析滿意度對於使用者願付價格之影響。研究結果顯示，包括遊憩動機、遊客特性、社經背景、及使用者滿意度等因素，對於願付價格皆有顯著的影響，且滿意度分數愈高者，其願付價格愈高。而願付價格金額之分析則顯示，不論是Tobit模式或多元線性迴歸模式之估計結果，均顯示淡水金色水岸自行車道使用者之願付價格約為20.07元。
