本研究結合雙向無線通訊技術、網路傳輸技術及資料庫管理技術，由自行設計的星狀雙向無線通訊協定和最短取車路徑規劃程式，發展出一套停車場智慧型取車導航系統(United Parking System, 簡稱UPs)，並於桃園縣公有府前停車場建置啟用。其主要功能為準確紀錄停車區域、提供最短取車路徑、提供停車場空間資訊。 此系統改變立體停車場的使用模式，以自動化的系統管理，將桃園縣府前公有停車場地下三樓劃分成12處停車區域並設置停車區域記錄器，且於地下一樓出入口處設置三部取車導航電腦，搭配區域的標示牌指示牌，幫助使用者記憶停車區域，提供最短取車路徑規劃以縮短使用者取車時間，降低尋路的困難與迷失的發生。 由現場使用者問卷調查的結果顯示，211份回收問卷中，有80%以上的使用者認為本系統的建置與使用確實能幫助使用者建構停車場的空間概念、省去記憶停車區域的困擾、降低取車所花費的時間、增加處於停車場之中的安全感。以上結果驗證了本研究所開發的系統已具有實用價值。 The United Parking System (UPs) was developed for drivers to quickly and effectively pick up their cars in the parking lot. By using wireless communication technology, network transmission technology and database technology, we designed a sophisticate wireless networks as well as windows-based navigating terminals (WNT) to help drivers finding their cars in the shortest route without memorizing their original parking locations. The main functions of this system are to login driver’s parking area accurately; to offer the shortest path while pick up the car; and to provide the geographic information of the parking lot. In this research, the UPs was built and installed at the underground parking lot of Taoyuan Prefecture Government for a three months long field test. The parking lot has three decks. The third deck was divided into 12 areas each equipped with an Area Data Sender (ADS) for drivers to log their original parking positions. Meanwhile, on each of three main entrances of the lot, a WNT was installed near the Auto-Pay Station (APS). With this design, the driver could see a map that indicated the shortest route from his/her current position (the APS) to his/her own car on the WNT screen when he/she returned to pay fees. An on-site questionnaire was given to the driver who just used this service. At the end of the study, 211 copies of questionnaire were received, and the results showed that over 80% users consider that the UPs did help them to reconstruct the concept of space in parking lot, to avoid wasting time in finding their car, and to enhance the sense of safety while walking in unfamiliar confined spaces. The results demonstrated that the UPs is capable to be a great tool for picking up cars in parking lot.
