無線射頻辨識技術應用於道路交通緊急號誌
Application of RFID Technology to Emergency Traffic Signal Design
摘要
隨著科技時代不同，在台灣這地狹人稠裡交通問題顯著，尤其是在於緊急車輛通行的時候，有鑑於汽車駕駛在道路上的禮讓觀念並不理想，為得到雙贏局面，可利用現有科技RFID射頻無線電來做交通道路號誌改善，這不僅可以縮短緊急車輛通行時間，同時又可去除不必要人力支援，而不用在執行定點式的調整交通號誌時間 就本論文中利用RFID射頻無線電去感應緊急車輛在道路行駛所需的距離、高度、方位，並架設READER讀取器來求得最佳的平均數值，在實驗中模擬道路交通號誌前60公尺處架設感測器所通過距離300公尺處路口時間與未加裝感測器所通過路口時間，二者差異時間所獲得秒數各為69.2秒與39.2秒，由此可見在裝設與未裝設前所得到的時間不同，這不僅可以改善在交通道路上的車輛擁擠問題，更可縮短緊急車輛抵達目的地時間，讓我們可以節剩更多時間來完成任務所需或是人力資源的調度分配。

With the changing technological era, traffic issues have become significant in densely populated Taiwan. The situation especially worse in the case of emergency vehicles, because most drivers do not yet the concept of yielding. For a win-win situation, state-of-the-art RFID technology can be leveraged to improve traffic signal design. The proposed method can not only shorten the travel time for emergency vehicles, while at the same remove unnecessary manpower support such as specific location-based tuning of signal timings. In this work, the RFID technology is used to sense emergency vehicles approaching on the road and to estimate the distance between the approaching emergency vehicle and the following traffic signal, the height and the direction of the emergency vehicle. In the simulated experimental environment, an RFID reader is installed at 60 meters before the next traffic signal. The time required for an emergency vehicle to travel a distance of 300 meters is estimated using the installed RFID reader, while passing by the corresponding traffic signal. The average time required when no emergency signal system is installed was 69.2 seconds and that when emergency system is installed was 39.2 seconds. The installation of an emergency signal thus reduces the travel time of emergency vehicles by improving traffic congestion. The saved travel time can thus be used for emergency handling.
