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.
