因應臺鐵轉型及臺南車站地區都市更新發展、消除鐵路對市區之阻隔、疏解日益嚴重的都市交通、整合都會區運輸系統，交通部鐵路改建工程局研議辦理「臺南市區鐵路地下化計畫」（簡稱：臺南計畫）。
臺南市區鐵路地下化計畫綜合規劃報告於98年9月9日奉行政院核定，計畫範圍北起臺南市永康區臺鐵大橋站南端(即柴頭港溪北岸)，地下化路線由既有鐵路東側岔出進入地下，行經北區、東區、至仁德區亞航社區附近爬升，再匯回臺鐵地面鐵路，全長約8.23公里，除將臺南車站古蹟保留外，另新建臺南地下車站，並增設林森、南臺南等2通勤站。
台南市政府基於永康、新市及善化等人口稠密地區，長期因臺鐵路軌造成都市空間分割，嚴重影響沿線兩側區域均衡發展，及軌道與路面平交易造成交通衝擊等因素考量後，遂委託專業團隊辦理鐵路立體化北延善化之可行性研究。
本論文試圖以「臺鐵地下化後永康火車站及周邊市區之空間發展研究」為空間探討意圖，綜合考量都市計畫、城市規劃、都市設計、建築師的角度，尋求一個理想銜接「臺南市區鐵路地下化工程」為主要架構的永康火車站及周邊市區都市設計方案。
在站區發展願景上，原都市計畫定位本區的站區發展願景為「田園都市新住宅」，透過本研究構想，期許未來站區範圍周遭將轉變為移居宜居的「韌性海綿新城市」，並且可以成為區域新發展中心區，對永康市區帶動更進一步的都市發展，重新成為一個臺南市區都市門戶，及交通大眾運輸的運能節點。

In response to the transform of the Taiwan Railway and the urban renewal and development of the Tainan Station area, the elimination of railway barriers to the urban area, the easing of urban transportation, and the integration of the metropolitan area transportation system, the Railway Reconstruction and Engineering Bureau of the Ministry of Transport has considered“ the Construction Project of Underground Railway of the Tainan City area ". (called : Tainan Project).
The comprehensive planning report of the project was approved by the Executive Yuan on September 9, 1998. The scope of the plan starts from the southern end of Daqiao Station Station (that is, the north bank of Chaitou Gangxi) in Yongkang District, Tainan City. The east side of the existing railway exits into the underground,through the North, East District, climbs up near the AirAsia community in Rende District, and then rejoins the Taiwan Railway ground railway, which is approximately 8.23 kilometers in length. In addition to retaining the historical sites of Tainan Station, another new Tainan Underground Station is built. It also added 2 commuting stations such as Lin Sen and South Tainan.
Based on densely populated areas such as Yongkang, Xinshi, and Shanhua, the Tainan City Government has long considered the division of urban space due to the Taiwan Railway track, which has seriously affected the balanced development of the areas along the two sides, and considered traffic impact caused by the flat track and road traffic. A professional team was entrusted to handle the feasibility study of the three-dimensional railway extended north to Shanhua District.
This thesis attempts to use "the research on the spatial development of Yongkang Railway Station and the surrounding urban areas after the underground of the Taiwan Railway" as the space exploration intent, and comprehensively considers the perspectives of urban planning, urban planning, urban design, and architects roles, to seeks an ideal project connecting "Tainan "Urban Railway Underground Engineering".
In terms of station development vision, the original urban plan positioned the station's development vision of the district as "a new garden city residential house". Through this research concept, it is hoped that the future station area will be transformed into a livable "flexible sponge new city" .It can also become a new regional development center, driving further urban development in Yongkang City, and becoming a metropolitan gateway of Tainan City and a transportation node for mass transportation.
This thesis explores themes, focusing on the four main aspects of traffic and landscape, urban renewal, station image, and station design in the urban design category. The thesis originated from the transportation issues of the underground railway of Yongkang Station, and because of the underground railway of the original railway, a landscaped parkway was created. By re-integrating the road system, Yongkang Station has become a facade of Tainan City. The district must also take advantage of this opportunity to reverse the image of the old industrial area through urban renewal and reposition the role of industrial areas and railway stations in the city. Compared to the original city core in Tainan City, Yongkang City is eliminated. And the urban image of the station area mainly on the channel and the edge, once again retrieve the image of Yongkang's new human-centered station, which is mainly relocated and liveable. Through station design, landscape greening, and leisure facilities and other related urban design techniques, it brings a whole newYongkang station area. The new vision of the city makes Yongkang people no longer just passers-by and no sense of belonging. This is the greatest hope and vision of this thesis and the problem that this thesis hopes to solve.
In terms of spatial layout and open space system, since the back of the train station is mainly an old industrial area and there is no substantial dynamic line connection with the train station area, plus the old buildings, all industrial plants respond to industrial transformation And re-optimization considerations, the urban planning goals also prioritized the implementation of urban renewal across the two sides of the railway. This case took advantage of this opportunity to reconnect the new relationship between the front and back stations; and tried to demolish the two sky bridges on Yongda Road、a level crossing on the west side of the station area, and through urban renewal methods, relocate the old industrial area as a commercial area, residential area, office building and other spaces, and strengthen public facilities to create regional theme parks. The method of green covering sidewalks and street corner squares shape and optimize the livable new urban space.
On the moving line system, the space of railway after the underground corridor is vacated is converted and increased into a 30-meter wide green park road, and the provincial road on the east side of Yongda Road is combined with the original urban planning road and railway land to expand the road. The sixty-meter-wide road is a wide tree-lined green garden road, which effectively relieves the dilemma of provincial road crossing. It also extends north to south through all roads, reconnects the new relationship between front and back stations, and resolves local traffic problems.
