本研究提出捷運票價的訂價模型，主要貢獻有兩點，一、本研究提出兩種不同搭乘距離（長程與短程）需求函數之定價模型，長程與短程旅次的單程票與定期票價格會互相影響需求量的變化；二、所得不同族群對於搭乘捷運的偏好會影響定價的選擇，以及社會福利的變化，不同於Jara-Díaz等人，本研究提出一個一般性的分析方式，可以處理所得族群與捷運偏好非反向關係的情況，對於後續研究者在處理任何案例均可使用此分析模式。此外，把建構的模型應用在臺北都會區案例，以臺北市、新北市之臺北都會區大眾捷運系統的資料，在捷運公司損益平衡的情況下，探討社會福利最大的捷運定期票與單程票之定價。研究結果符合Leland and Meyer的發現，在探討的票價制定規則中，實施定期票政策所得到的社會福利和預估運量皆高於沒有實施定期票政策的結果。

This study develops a pricing model for the fare of public rapid transit. The major contributions are two folds. First, we develops the model for two demand functions with two riding distances. The prices of travelcard and one-way ticket for long riding distance and short riding distance will interact with each of the demand functions. Second, the riding transit preference of various income groups will influence the transit pricing and welfare changes. Differing from Jara-Díaz et al., our model proposes a more general analyzing approach by employing different selection order of income groups under the condition of different ticket prices for the data not satisfying the reverse relationship. Thus, this approach can be applied to any case of this problem. Moreover, our model is then applied to the case of the Taipei Metropolitan Area by dividing into two areas based on ticket charges for long and short commuting distance passengers to purchase. This study pursues maximum social welfare with the constraint of revenue being equal to cost for the optimal pricing. The results of the study show that in the pricing rules, the social welfare and estimated ridership obtained from the implementation of the travelcard policy will be higher than that with no travelcard policy, which is consistent with Leland and Meyer.
