摘要


20世紀末個人電腦問世以及網際網路應用,使得人類歷經了資訊革命,至本世紀初,資訊科技已經發展到相當成熟的階段,各種相關的技術被應用在社會各種層面上,資訊化將成為影響政府未來經濟發展的重要因素。因此在運輸政策上,傳統以工程方式興建道路以提升道路運輸量,現代化則透過資訊科技以有效的經營管理手段提高現有運輸設備效用,即智慧型運輸系統(Intelligent Transportation System, ITS)。 行政院於「挑戰2008-國家發展重點計畫」中提出「數位台灣計畫」中之「e化交通計畫」子計畫「交通服務e網通計畫」,該計畫明確指出建設提供用路人即時路況資訊系統,其於民國93年12月起正式由交通部運輸研究所建置推出「全國路況資訊中心網站」提供用路人即時路況訊息,用以滿足用路人行駛效率與滿意度,但觀察該中心網站總瀏覽人次發現使用率不高,因此有必要探討該中心網站使用者之認知、評價以及使用意圖,目的是用以增加該項政策使用率與滿意度。 本研究希望透過整理相關文獻資料及問卷調查法,從科技接受模型(Technology Acceptance Model)與其相關理論和資訊系統成功模式(IS Success Model)的觀點探討全國路況資訊中心網站的使用意圖;但該網站推出至今時間短,使用率不高,因此本研究為了避免研究失焦,進一步以內部政策行銷角度,將研究對象侷限在對交通業務較為專業熟悉瞭解的交通部公路總局人員。 本研究架構為九大構面,分別為形象性、主觀規範、知覺有用性、相對優勢、資訊品質、結果展示性、知覺易用性、知覺行為控制及使用意圖,希望透過此九大構面瞭解已使用過全國路況資訊中心網站者的使用意圖,並且透過個人背景變項分析瞭解對全國路況資訊中心無認知者以及未使用者之認知與使用情形。研究結果發現,影響使用意圖之因素為知覺有用性與知覺行為控制,其中相對優勢與資訊品質又會影響知覺有用性。

Computer networks produced an information revolution in the late 20th century. The resulting information technology continued to develop and mature during the early years of 21th century, such that various technologies have now found social application. At the same time, the production , distribution and application of information has become an important factor influencing government-directed economic development. Traditionally, engineers have looked to improve transportation networks by building roads to enhance traffic flows, but using information technology to design a more intelligent transportation system – ITS – it is now possible to achieve significant improvements by enhancing the effectiveness of existing infrastructure. In 2002, the Executive Yuan formulated “Challenge 2008 – National Development Plan”,which included the“Digital Taiwan Plan”,“Transport Service E-Network Plan”, and a sub-project: the“E-Traffic Plan”. The“E-Traffic Plan”was launched with the intention of building an instant traffic information system for road users. To provides users with real-time traffic information and realize greater efficiencies and a higher degree of user satisfaction, the Institute of Transportation in the Ministry of Transportation and Communication, established the“National Traffic Information Center”web service in December 2004. Based on observations of the number of visitors, this study finds that the web service is under-utilized. In order to increase usage and satisfaction, it is necessary to examine user perceptions, appraisals and intended usages. Using literature review and questionnaire survey methods, this study adopts the viewpoints of Technology Acceptance Model and Information System Success Model to investigate the factors that influence the ultimate usage intention of the“National Traffic Information Center”web service. Considering the short history and low-usage rates of this web service, this study limits the surveyed population to employees familiar with traffic affairs in the Directorate General of Highways. This study is based on nine research constructs: image, subjective norm, perceived usefulness, relative advantage, information quality, result demonstrability, perceived ease of use, perceived behavioral control and behavior intention of use. By analyzing the different personal background of users and non-users, and their perceptions and usages of the“National Traffic Information Center”web, this study aims to understand the real usage intentions of web visitors. The research results show that factors influencing usage intention are the perceived usefulness and behavioral control. In addition, relative advantage and information quality affect the perceived usefulness.
