摘要

高速公路電子收費系統（ETC）為智慧型交通運輸系統（ITS）的重要子系統之一。ETC以資訊科技為基礎的系統，當車輛安裝車上設備（OBU）或電子無線射頻標籤（eTag）後，ETC透過電子識別向車輛收取過路費，讓駕駛人可在免停車或減速的情況下通過收費站完成繳費動作。即使ETC有減少交通擁擠、不用停車之優點，但使用率一直低於預期。高速公路局為了減緩收費站前的停等時間，並考慮公平收費的原則下，預計將實施電子計程收費系統。由於台灣ETC的使用率偏低，本研究主要為探討採用ETC服務的態度和行為意圖之影響因素。由研究結果發現，在以科技接受模式為基礎下，對於ETC的認知有用性與認知易用性對於使用ETC的態度皆有正向影響，而認知易用對認知有用有正向影響。在計畫行為理論的基礎下，高速公路使用者對於ETC的使用主要是受其對ETC使用態度的影響；ETC使用主觀規範與ETC使用知覺行為控制皆無顯著影響。

The Electronic Toll Collection (ETC) is part of the Intelligent Transportation System (ITS). It is an information system that makes drivers install On-Board Units (OBU) or eTag and charges vehicles as they pass through a tollbooth without stopping or slowing down. The current ETC is a toll-based collection system in Taiwan. Despite the potential benefits for reducing traffic congestion, the utilization rate of ETC for drivers has been lower than expected. In order to alleviate traffic delay in tollbooths and consider equity principle in toll collection, the electronic distance-based charging system (EDBS) will be implemented overall on freeways.Because of the low utilization rate of ETC in Taiwan, this study wanted to explore the factors affecting the attitude and behavior intention of ETC service adoption. Based on technology acceptance model and the result of this study, it could be finding that the perceived usefulness and the perceived ease of use are positively associated with users' attitude toward using. A useful and ease of use ITS product can improve users' attitude of using it. Based on theory of planned behavior and the result of this study, users' attitude is positively associated with behavioral intention. Subjective norm and perceived behavioral control are not positively associated with behavioral intention significant. So users' attitude played an important role in using ETC. Besides, perceived usefulness and perceived ease of use are positively associated with behavioral intention indirectly.
