摘要

智慧型運輸系統(Intelligent Transportation System；ITS)是一整合許多設備，藉由現今先進之電腦、資訊、電子、通訊與感測等科技的應用，透過所提供即時(real-time)資訊的溝通與連結以協同合作的方式來改善人、車、路等運輸次系統間互動關係的大型系統。然而，由於各式設備都具有其獨特的資料格式與通訊協定，例如GPS、TMC、Wi-Fi或Bluetooth等，因此設備間無法直接相互交換資料。
本研究提出一套在ITS中資料整合交換之機制(Integrated Data Exchange Platform；IDEP)，此機制包含四個層級以及數個元件分別作為資料的收送、加解密以及分派等，可將由外在設備收到的資料重新包裝成所設計之XML資料交換格式後，再經由不同傳輸方式發送給其他設備。且為求資料安全之考量，傳送之資料內容更可經由AES加密以達保護之作用。經實驗證實，本研究所提出的機制不但可行，且在資料量增加的情形下運算的時間亦不會顯著增加。因此，此機制可在少量運算下即可達成在各式設備間互相交換資料之目的。

An Intelligent Transportation System (ITS) incorporates a variety of equipment and devices all working in mutual harmony. However, each piece of equipment or device has its own data format and protocol such as GPS, TMC, Wi-Fi, and Bluetooth. Therefore, they cannot exchange data with each other directly. In this paper, an integrated platform of data exchange in an ITS is proposed that can receive data from several types of equipment external to automobiles, repackage the received data, and then dispatch the data to different devices inside the vehicles. Based on this platform, data in equipment and devices can be interchanged to share data.
