    Abstract: 當今是全面數位化的網路生活時代,學術文獻已從紙本形式轉變為電子化形式,充足便利的電子文獻資源大幅降低知識擴張的空間障礙,知識得以廣泛的傳播,以為後人所借鑑,因此電子化資料庫成為一項學者進行研究的有力工具。臺灣目前知識領域視覺化相關研究產出鮮少,運輸科學研究領域亦是如此。有鑒於此,本研究嘗試結合國內外知識產出繪製出知識圖譜,全面統計產官學研多面向文獻成果,深入瞭解我國ITS領域之知識產出及其學術群聚現況。



    The academic literatures have been transformed in the form of paper into electronic one due to digital life with Internet nowadays which can overcome space obstacles of knowledge expansions. Therefore electronic database on the web are one of powerful resources for researchers. However, there are few studies on knowledge mapping in the field of transportation science in Taiwan. This study aims at providing knowledge maps of ITS and quantifying ITS knowledge outputs with clusters by subjects, institutions and authors in Taiwan.

    The empirical study is conducted based on English ITS database on the web. Global ITS knowledge maps are drawn by using CiteSpace software to demonstrate co-citation networks which nodes include countries, authors and keywords. The same approach is applied to domestic ITS knowledge maps. Because there are no electronic database for ITS in Taiwan, manual screening of ITS documents is inevitable and ITS knowledge maps are drawn by using Ucinet software in order to demonstrate ITS knowledge outputs with clusters by subjects, institutions and authors in Taiwan.

    The results of the empirical study show that research developments of ITS are very promising worldwide. CiteSpace is proven to be a good tool for demonstrating ITS knowledge maps with clusters by subjects, institutions and authors. Most of ITS knowledge outputs focus on ATMS, and then on ATIS. Six universities such as National Cheng Kung University, National Taiwan University, National Chiao Tung University, Tamkang University, Feng Chia University, and Chung Hua University are identified to be prominent institutions of ITS knowledge outputs in Taiwan. Especially, most of ITS knowledge outputs are ATMS, while outputs in CVOS and AVCSS are also found in National Chiao Tung University and ChungHwa University.

    The ITS knowledge outputs with clusters by authors are finally summarized to assess their research performance by using AHP. The ranking results and corresponding knowledge maps provide an overview of current performance status of ITS scholars in different ITS service areas in Taiwan. The approach in this study can be adapted to other disciplines with similar processes. The manually summarized ITS database can also be regarded as references for those researchers who need academic ITS developments from 1990 to 2010.
