中文摘要 道路安全巡察是道路維護重要的一部分,巡察員定期檢視分配的道路路段,若發現道路或是一些公共設施像是紅綠燈損壞時,再以相機、智慧型手機拍照記錄。一般市民若發現有任何危害交通的事物,可利用查報系統通知相關人員處理。
近年來政府也使用專門的衛星道路巡察車負責此業務,一旦發現道路問題時則利用車上的攝影機以及衛星定位回報維修部門。傳統的巡察作業與故障維修查報花費很多人力成本外,也需要不少往來交通時間。衛星巡察車雖然可減少部分時間花費,但仍需相當的人力成本,此外衛星道路巡察車的造價也是十分昂貴。
本篇論文發展一個支援道路巡察的資訊系統,利用十分普及的行車紀錄器或者智慧型手機,將行駛中道路上拍攝的街景影片上傳至系統,讓巡察人員點選所需觀看的路段街景影片。此系統提供了三種功能,影片及相關位置資訊檔案上傳、顯示可觀看影片的路段地圖及播放選擇路段影片。這個系統可以輔助原本的道路巡察作業,精簡作業流程,減少人力與時間的花費。
英文摘要 Road safety inspection is an important part of road maintenance. The road inspection typically depends on road inspectors to do regular check-ups in their responsible areas.

If the inspectors find damaged roads or broken facilities such as traffic lights, they will note them down with their cameras or smart phones. Sometimes, citizens report the damaged road condition, and then the inspectors con rm the damage in person. The method needs a higher input of labor and longer process time.
In recent years, satellite inspection cars were introduced for road inspection. Inspectors use cameras and a satellite positioning system to document noticed damages. The satellite inspection car shortens the time for road inspection. However, this method still
needs extra staffs to carry out the task. Moreover, the satellite inspection car is very expensive.

This thesis introduces a system for supporting road safety inspection. Citizens use mobile devices to record videos and location information when they are driving. The videos then can be uploaded to the system. The system shows the roads of which videos are available. Road inspectors select needed road segments to watch the corresponding videos, so they can collect the information without going to the damaged spots. The system can reduce required inspection manpower, cost, and time.
