dc.description.abstract近年來國內政府正積極推動智慧型運輸系統的相關建設,希望透過先進的通訊網路技術與現有運輸設施的結合來改善目前國內交通擁塞的狀況。然而智慧型運輸系統所涵蓋之範疇相當廣泛,往往會因為其應用範圍的不同,產生出不同的通訊需求,進而導致其所使用之通訊網路也會有所差異,若是無法對其應用特性評選出適當通訊網路,則會對系統整體的效能造成不良的影響。 在國內之前的研究中,主要是以通訊需求為出發點,以模式構建的方式來進行各個通訊系統的中傳輸資料量與頻寬的分析,而後再以此來判斷各個通訊系統於不同路網特性的適用程度。但在此方法中無法將車輛於路網中的行駛特性納入考量,故本研究則提出以系統模擬的方式,針對大眾運輸車輛的行為來進行車輛行駛特性的分析,並以此為基礎探討資料於不同通訊網路服務下的傳輸行為,而後則以平均資料傳輸時間、阻斷率及跳站機率三者來進行各個通訊網路效能的評估。 為了解本研究所建構系統之效能,本研究以新竹市大眾運輸系統為例進行測試。測試結果顯示新竹市的大眾運輸系統在資料量需求較小時,各個目標系統均可以提供服務,其中又以GPRS系統平均傳輸時間最小。zh_TW
dc.description.abstractIn recent years, the government wants to improve the traffic congestion by promoting intelligent transportation system (ITS). Most of the ITS application have some components involving the data transmission between vehicles and control centers. Thus the ultimate selection of communication system will affect the performance of ITS network. The purpose of this research is to evaluate suitable communication networks for ITS applications, based on a through study of the characteristics of data transmission process. The analysis of ITS communication demand is first proposed, and then a simulation structure is established through estimating the parameters of vehicle behaviors and wireless communication network. Finally, a computer software for evaluating the communication networks suitable to ITS applications is developed.en_US
