台灣高速鐵路全長345公里，縱貫整個台灣西部走廊，影響範圍涵蓋大半個台灣。除了扮演著台灣西部走廊的交通命脈以外，政府又賦予高鐵另一個偉大使命扮演國土規劃的角色。在密集場站開發的規劃下，未來高鐵各站都將帶動地方發展，使得這些地區成為一個個新興的市鎮。從五大車站產業專區的區位條件觀之，五站各有其特性與發展利基。桃園站雖地處偏遠，但因擁有得天獨厚的桃園國際機場，且擁有與大台北連接的機場捷運系統，則有助於發展為國際商務城市。同時高速鐵路將串聯台灣南北原有的台鐵系統以及各大都市的捷運系統與公路客運，形成高速大眾運輸網絡，貫徹「大眾運輸為主、私人運輸為輔」的目標，使城鄉區域發展更臻完善。為了因應高鐵旅客轉乘之需，各站區除針對聯外道路系統加以改善外，政府並規劃軌道（包括鐵路及大眾捷連系統）及公路運輸之聯外交通系統。

Taiwan High Speed Rail, whose route is 345 km in length, mainly serves the western corridor of Taiwan that affects almost half portion of it. It is not only an important transportation lifeline of Taiwan western corridor, but also been granted a great mission as the national territorial planner. Under intensive station area development planning, each station is in charge of triggering the development of nearby local area to be a new town. From the point of geographical feature of five major station areas, each station has its own characteristics and strengths. Although Taoyuan Station is located at a remote area, it possesses an unrivaled advantage that located nearby Taoyuan lnternational Airport and having the airport link MRT connects to the Taipei metropolis that contributes to the development of being an international commercial city. Meanwhile, Taiwan high speed railway system is integrated with the conventional railway system, as well as the MRT and bus systems at each metropolitan area to be a high speed mass transportation network, to fulfill the target of "Public transportation the first, Private transportation the second", and to balance the development of countryside and urban areas. For the requirements of passenger transfer of high speed rail, the outreach transportation systems, including freeway and railway systems, were improved by the government at each station area.
