Abstract

省道肩負著國道替代道路的使命,但在國道發生壅塞時,用路者卻往往無法得知省道路況,而可能錯失其選擇最佳路徑的機會,不但影響用路者行車品質,更影響整體道路的使用效率,並增加社會成本。為了擴充省道路況資訊,本研究擬探討國內客、貨運輸或其他具規模車隊作為探偵車的可行性,並實際彙析探偵車之行駛資訊,進而轉換為省道路況資訊;另一方面,傳統蒐集路況資訊之偵測器,多直接引進國外產品,不但價格昂貴,其維護及相關技術都受限於國外,爰此,本研究將研析國內研發偵測器的可行性,並探討研發偵測器可能面臨的相關課題。本研究期望藉由固定式偵測器及移動式探偵車議題的探討,建立未來省道路況蒐集的方式及機制,另為了將所蒐集資料提供給民眾及加值業者使用,本研究同時將建置速率資訊蒐集、處理及發佈的平台,提供網際網路式之路況(速率)資訊顯示系統。
The provincial highways serve as important alternatives for national highways. However, the lacking of traffic condition on these provincial highways is a must address issue for improving the efficiency of transportation system. The goals of this research include: (1) studying the feasibilities of using related vehicle as probe vehicles to collect traffic information, (2) developing the core techniques of developing economic vehicle detectors, (3) studying a web-based platform of collection, exchanging, processing, and broadcasting traffic information.
