協同式行車安全技術於車間短距無線通訊(Wireless Access in Vehicular Environment/Dedicated Short Range Communication ; WAVE/DSRC)標準經過四年(2008~2011)的制定與二年(2010~2011)的互通 性測試後，終於進入場域實車驗證階段，為了收集場域行駛車輛的即時資料、增強車機的金鑰管 理與憑證更新、與提供優質化行車服務，在場域內需大量佈署路側設備，考慮戶外路側設備管理 與維運等因素，故運用彈性化、模組化之設計；在本論文中，我們提出一套髙可用性路側設備架 構，由一個中央控制單元與四個的無線裝置，組合成一套路側設備，經由後端操作管理維護中心 監控其功能；本文詳細描述其系統需求、功能、流程，最後並做結論。

Wireless Access in Vehicular Environment/Dedicated Short Range Communication (WAVE/DSRC) standards of cooperative vehicular safety technology has been developed for four years (2008~201 1 ) and the interoperability testing during two years (2010~2011). Finally, they will begin to enter the real field testing of verification stage. In order to collect the real-time data of traveling vehicle, enhance the encryption key management and certificate updating, and provide the quality of traffic services, we need to deploy several Roadside Equipments (RSEs). Because considering the outdoor operation and maintain factors, we adopt the flexibility and modulation design. In this paper, we propose the high availability architecture, composed by one control unit and four radio sets and controlled by the operations, administration and management center. Later, we describe the system requirements, functions and process flows and make the conclusion.
