本研究旨在分析輕軌運輸系統與單軌運輸系統之優劣，探討兩者在都市區域內應用之可行性。根據臺灣軌道建設之過往經驗，主要採用高運量捷運系統及輕軌運輸系統。近期臺灣在規劃新的都市軌道運輸路線時已將單軌運輸系統列入考慮範圍，惟尚無實際應用先例。
本研究聚焦於以下幾個項目進行探討。分別為分析輕軌與單軌運輸系統對原有道路設計之衝擊、評估兩者於運行過程中之環境噪音影響、逃生救援方法之有效性及研究高架橋建設對原有道路設計之衝擊與行人之遮蔽率影響及養護程序之差異。通過研究，旨在了解輕軌與單軌運輸系統之間的差異，並據此評估特定地區適用之軌道運輸系統，以提升都市交通效率，滿足交通需求。
經由以上四項探討可知，單軌運輸系統在噪音影響及建置環境衝擊，相較於輕軌運輸系統較小且差距甚微。此外，單軌運輸系統適用多種逃生救援方案，並加以確保乘客之安全並消除其顧慮。

This study aims to analyze the advantages and disadvantages of Light Rail Transit (LRT) systems and monorail transit systems, exploring their feasibility in urban areas. Based on Taiwan's past experiences in rail construction, the primary choices have been high-capacity metro systems and LRT systems. Recently, Taiwan has considered including monorail systems in the planning of new urban rail transit routes, although there are no actual applications yet.
This research focuses on several key aspects, including the impact of LRT and monorail systems on existing road designs, the assessment of environmental noise impacts during operation, the effectiveness of evacuation and rescue methods, and the influence of elevated bridge construction on existing road designs, pedestrian shielding rates, and differences in maintenance procedures. Through this analysis, the study aims to elucidate the differences between LRT and monorail systems and to evaluate the most suitable rail transit system for specific areas, thereby enhancing urban transportation efficiency and meeting transportation demands.
The findings indicate that the noise impact and environmental disruption caused by monorail systems are relatively minor compared to LRT systems. Moreover, monorail systems can accommodate various evacuation and rescue schemes, ensuring passenger safety and alleviating concerns.
