本文以台北市中華路一段為例,以視線權力、空間修補及基礎設施僵固性等解釋道路形構的不同觀點,探討體現於道路基礎設施變遷的社會物質性。台北市的道路規劃理念歷經兼具衛生、秩序、景觀和效率的現代化道路格網、立體化設施,以迄晚近強調的人本及綠色交通。原為台北城牆西段的中華路一段,自拆除城牆興建三線路以來,其路型更迭體現了前述轉變,並顯示視線權力和空間修補的塑造力量。然而,溯自城牆位置的道路方位和規模,持續框限了城市格局;日益增添的通訊和維生管線也受制於既有通道,展現了基礎設施的僵固性。僵固性也有利於維持城市景觀穩定,裨益於都市自明性和環境認知。視線權力、空間修補和僵固性構成了道路之技術政治的不同向度。
Based on one case study examining the Section 1 of Zhonghua Road in the Taipei City, this article discusses the vicissitudes of the road which epitomized the social-materiality of infrastructure. The author explores different explanatory models with regard to visionary power, spatial fix, and infrastructural obduracy. The planning idea for the roads in the Taipei City has undergone several phases. The roads were first dominated by a modernized configuration featuring hygiene, order, tidy landscapes and efficiency, and were later endowed with three-dimensional road facilities. Recently, a human-oriented planning approach emphasizing "green transportation" has also been gaining popularity. Sec. 1, Zhonghua Rd. has testified to such alteration and revealed the dynamics of visionary power and spatial fix as it is the location where the western side of the old city wall during the Qing Dynasty was demolished and replaced by the three-lane road built by the Japanese. However, the road disposition resulting from the city wall does not lose its sway and has been framing the urban pattern ever since then, which restrains the contemporary channels for distributing telecommunication infrastructure and pipelines for basic livelihood. This is where infrastructural obduracy manifests itself and contributes to the stabilization of city landscapes, gracing it with self-identity and higher environmental legibility. Finally, the author argues that visionary power, spatial fix and obduracy make up the dimensions of techno-politics of the road.
