公路電子收費系統的實施效益，涵蓋各種層面，惟實施過程中，不論從自動化執法系統的配合或車旅及個人化資料的保全、傳輸及處理等而言，稍一不慎卻可能涉及個人隱私權保護等相關課題。因此，本研究即以電子收費自動化執法系統架構的建置與需求規劃作為基礎，就其實施可能涉及的相關法令與執法問題，諸如法源依據、執法現況、新的交通執法技術與取向等、以及未來考慮進一步擴大實施時，對個人隱私權之衝擊、隱私權之保謢及其相關課題等進行探討，參酌國外對個人隱私的保護與規範，以及國內未來在執行上的問題與需求，如交通執法課題、個人旅次資料的應用、資料的保全以及未來第三者資料的取用等相關課題加以剖析；本研究結合電子收費與執法技術之實務層面，從人性的觀點與法理的需求間之兼顧考量，可有效提供未來在執行面上，對於隱私權保護的相關具體方向，將更能確保電子收費的效率與品質。

The introduction of Intelligent Transportation System (ITS), and in particular Electronic Toll Collection (ETC) can offer significant benefits to the motoring public. In Taiwan, the freeway toll system may reach a new stage due to the on-going development in ETC system. However in the course of testing, the high number of violation cases and various highly dangerous illegal driving behavior when passing the toll plaza can reveal the importance of traffic engineering planning and the functions of enforcement for the implementation of ETC. Furthermore, unless carefully managed, the vast information flow associated with ITS applications (i.e.,automatic enforcement) can threaten personal privacy, and contravene the community’s privacy expectations. This research forcus base on the enforcement system funtion design and examines ITS privacy issues, particularly in the context of ETC, and discusses steps which toll road operators, consumer groups, and governments might take in order to accommodate the community’s concerns.
