本文就臺灣之典型中型都市－臺南市大眾運輸之現況根據調查資料進行一說明及分析，並對未來之發展做一初步的展望。首先概述臺南市都市發展之背景，了解市區公車之先天不良營運環境，並藉訪談整理業者、管制者與專家學者對市區公車系統改善之看法與建議，然後經由問卷調查，分析臺南市民使用市區公車之現況與對大眾運輸改善政策之意見，獲知民眾認為改善公車之營運仍為最優先之課題。公車之改善，本文認為競標制度可提昇公車營運之績效，並對其可行性做一探討；而引進新運具方面，目前雖已規劃捷運系統，但其造價昂貴、需求量亦不高，或許引進輕軌系統為一可行之替代方案，因而本文亦對臺南市引進輕軌系統之可行性做一初探。

　　　　　This paper discuses the existing characteristics and future perspective of the public transportation for a medium size city in Taiwan-Tainan city based upon survey data. Firstly, the unfavorable operating environment is reviewed from the viewpoint of urban development. And then, through interviews to the operators, regulators of public transport services and experts, as well as through questionary survey, the behavior characteristics of current bus users and comments/suggestions to improve public transportation are investigated and analyzed. We think the tendering system has the potential to improve the operating performance of bus, therefore, its feasibility is discussed. With respect to new public transport facilities, the light rail system may be a better system them the conventional metro system because the metro would be too expensive and the demand would be not high enough. Therefore, a preliminary discussion of the feasibility of introducing light rail system to Tainan city is followed.
