本研究以日治時期桃園軌道株式會社與中壢軌道株式會社所經營之中壢線為核心，探討人力輕便軌道對中壢交通發展與都市空間變遷的影響。清代中壢道路狹窄、交通條件有限，至日治初期因米穀、茶葉等物產運輸需求，以及殖民政府對地方交通的制度規範，人力輕便軌道逐漸成為中壢近代交通建設的重要起點。 本文透過日治時期地圖、戰後地形圖、都市計畫圖與當代道路圖資之對照，分析中壢線自1904年至2020年間的空間延續與轉化。研究發現，人力輕便軌道不僅具有產業運輸功能，其路線亦成為中壢早期現代道路的基礎。1938年軌道拆除後，部分舊線並未完全消失，而是在戰後道路化、市街擴張與工業發展過程中，以道路、巷弄或交通廊帶的形式延續下來。 然而，這些由輕便軌道轉化而來的道路，也因原有線型曲折、路幅狹窄與土地使用變化，逐漸形成今日中壢市區不規則街廓與交通瓶頸的一部分。本文進一步指出，當代桃園捷運綠線延伸中壢段，某種程度上重新回應了中壢長期以來的交通廊帶需求，使日治時期地方交通建設與當代大眾運輸規劃產生歷史連結。 透過中壢線個案，本文說明人力輕便軌道雖已退出歷史舞臺，卻仍透過道路紋理、街廓形態與都市交通結構，持續影響中壢城市發展。本文期望藉此補充日治地方交通史與都市空間史之間的討論，並提供理解當代中壢交通問題的歷史視角。;This thesis examines the influence of push-car railways on the transportation development and urban transformation of Chungli， focusing on the Chungli lines operated during the Japanese colonial period. In early twentieth-century Chungli， the demand for transporting rice， tea， and other local products made push-car railways an important basis of modern local transportation. By comparing historical maps， topographic maps， urban planning maps， and contemporary road maps， this study traces the spatial transformation of the Chungli lines from 1904 to 2020. The research shows that the push-car railway was not only a tool for industrial transportation， but also formed the foundation of Chungli’s early modern road system. After the tracks were removed in 1938， some former railway routes were transformed into roads， lanes， or transportation corridors during postwar urban expansion and industrial development. This thesis argues that the spatial legacy of the push-car railway remains visible in Chungli’s road patterns， block forms， and traffic structure. Although the railway itself has disappeared， its routes continued to shape the city’s development and limitations. Through the case of the Chungli lines， this study connects local transportation history with urban spatial history， and provides a historical perspective for understanding contemporary transportation issues in Chungli.
