本研究透過質化研究中之個案分析為調查基礎，構建智慧城市路線圖的過程，提供了一個技術路線圖以及一些針對城市的政策建議。技術地圖方法論開發了一個三階段過程，第一階段我們彙整背景、介紹智慧城市發展的資通訊科技項目，搜集了全球80個標竿智慧城市發展案例；第二階段盤點技術及應用清單；第三階段是技術成熟度的專家預測階段，透過36位智慧城市領域專家進行問卷檢視，分析在智慧城市中，其技術應用與市場產業等成熟和關連性，藉此了解目前智慧城市的發展現況給予未來智慧城市發展建議。
最後，彙整並萃取出目前智慧城市普遍發展之13個重要的關鍵技術以及42個應用項目，並以技術地圖架構為基礎，將智慧城市的技術與應用層次由底層向上依序分類為「感知層」、「整合層」、「智慧判斷層」與「應用層」等四個層次，建構智慧城市技術應用藍圖。此研究身為智慧城市領域技術預測分析初探之基礎，可作為日後相關產業廣泛性了解重點技術及應用之發展趨勢，以及政府政策發展智慧城市之參考依據。

Based on qualitative case studies, this paper investigates the process of building a smart city roadmap, providing an example of such a roadmap along with some policy recommendations for cities. A 3-phase-process is developed where first literature is reviewed and based on common criteria development cases from 80 cities are gathered. The 2nd phase builds up a technology inventory for the selected cases. The 3rd phase is the expert prediction phase for technology maturity, in which technology development predictions are used to establish the causal relationship between technology and the timing of its application. This process produces a technology roadmap which is then used as the basis for organizing smart city technologies and applications into four ascending layers: Sensor, Integration, Intelligent, and Application.
The result is a blueprint for the application of smart city technologies. In addition, 36 smart city experts were surveyed to assess the maturity of and connection between smart city technologies, markets, and industries. Current smart city developments can then be ascertained to provide recommendations on smart city development. This preliminary forecast and analysis of smart city technologies can be applied to related industries to gain a general understanding of trends in the development of key technologies and applications.
