公共腳踏車系統設計模型實用分析

ANALYSIS OF PRACTICAL IMPLEMENTATION FOR A PUBLIC BICYCLE SYSTEM DESIGN MODEL

本研究以可應用於實際大規模問題為目標，建構一個公共腳踏車系統設計規劃模型。提出的模型以整合的觀點，同時考量使用者、系統建置者、系統服務水準的不同角度，尋求權衡下的最佳的設計。模型主要針對公共腳踏車系統長期的策略型規劃決策，用以決定公共腳踏車租借站的數量、位址、連結站點間腳踏車道的網路路線結構、使用者步行、借車、還車的路線。以YouBike初始推動時的示範營運計畫區域當作測試平台，驗證所提模型的正確性及實用性。針對重要參數進行敏感度分析，從中歸納釐清影響及互動的關係。這些參數會隨不同地區、不同旅次、不同使用者，而有所變動，有助於了解不同情狀下對應的結果，讓模型可適用於不同的情狀，不只是應用於測試的實例，所得結果在實用上及學術上都具有參考價值。

This paper illustrates the practical implementation of a strategic public bicycle sharing system design model that provides an integrated view of user travel costs, system investments, as well as coverage quality. The key decisions consist of strategic decisions on the number and locations of bike terminals in the system, the network structure of bike lanes connected between the terminals, and the travel paths for users between each pair of origins and destinations. The design decisions involve finding an appropriate trade-off between the overall cost and the service level. The results of this study confirm the usefulness of an integrated strategic model to support the public bicycle sharing system design. A real network based on the initial program of Taipei YouBike system was used to illustrated practical implementation of the proposed model. Sensitivity analysis is also performed to gain better insights into knowing how several important parameters affect the design of the system. The proposed model could be useful for both practitioners and researchers.
