学科:台湾主要城市客运铁路干道路廊与设站策略更新之探讨/摘要

摘要

交通部铁路改建工程局近期对台湾各主要城市客运铁路干道路廊与设站策略之更新，于新闻媒体、社会大众及政治界各方领域内均产生极大的回响，在透过互联网传播导致资讯流通飞快之环境下更掀起热议，尤以铁路立体化（高架化及地下化）及铁路捷运化两大发展方向为甚，除对未来运输环境改善、产业扩张及用地再生之愿景展望外，亦于政治界或民间产生若干争议，其中许多由对铁路立体化及捷运化技术、概念及设计层面之误解所致。

本篇专题志于厘清此等策略更新之脉络，自概念、历史、效益、实行技术、配套措施等各方面进行简略探讨，未来可再基于其成果，普及大众对其之理解，消除讹误及争议，令铁路运输切实成为推动城市发展进步之重要一环，并免于成为争议与冲突之导火线。

本篇专题之内文分为两大部分，分别探讨铁路立体化及捷运化。以铁路立体化作为主题之第一部分中，论述铁路立体化之缘起、简史及效益之例举，对台湾本土铁路立体化建设之经验整理，分析大众媒体所指，地面铁路造成地区切割、交通瓶颈等问题，最后进行高架化与地下化二大立体化方案之比较；以铁路捷运化作为主题之第二部分中，论述传统铁路与捷运系统之传统角色分工，探讨促进都市分区发展及旅客分流与去中心化等铁路捷运化愿景之相关概念及可能成效，末尾分析台湾铁路捷运化实行面临之难题。

The Railway Reconstruction Bureau under the Ministry of Transportation and Communications has put out several renewing projects for it's route designing and station location selection in the recent years, the messages has taken social medias by storm and the public attention has arroused, especially by two major kinds of renewing projects: the Grade Separation Project, including Railway Elevation and Underground Project, and the Railway Rapid Transit Systematization Project.

These projects are designed to improve the current conditions of transportation, encourage the expansion of industries, increase space for other projects to ameliorate the urban environment while the railway has been elevated or built underground, etc. However, several controversies has came from the implementation of these projects as well, and many of them are derived from the misunderstoods of the technologies, concepts, and designs related to these projects.

The target which this article aiming, is from conceptional, historical, technological and implementational point of views to compose a simple research on these projects, to clarify their sequences, and make it possible to serve as a foundation of future popularization of clear understadings on these projects, after all the misundertoods and disputes are amended, the railway transportation could truly became the power that pushes the metropolitan development, so do I prospect.

I've diveded the body of this article into two major parts. the first part is focus on the Grade Separation Project, it discussing histories, examples and outcomes of grade seperations of railway networks at the beginning, take a look at what Taiwanese railway industry have experienced, analysing two problems that often being mentioned on the media articles related to the project, the diviation of living sphere, traffic congestions caused by the ground railways, and compare the elevation and underground method at the end of this part.The second part is focus on the Railway Rapid Transit Systematization Project, it discussing the traditional positions of the Traditional Railway System and the Mass Rapid Transit System on a divided work, investigate around the prospects of the project such as stimulaton of urban divisional developments, diversion of passenger flow, decentralization of major transportation terminals and so on, analysis of the difficulties the project will face in Taiwan at the end.
