機車停等區與機車二段式待轉區為配置為號誌化路口幾何配置組成之一部分,該設計使得機車於路口之紓解與運行發生分流,機車於路口停等具向前集中與橫向擴展之特性與機車高機動性、低啟動延滯特性,機車停等區可以供給空間予機車紓解,並減少後方汽車車流之干擾衝突,以提升整體車流之效率。 機車停等區長度與號誌之影響關係為本研究之主題,最適之停等區長度可於滿足機車集中紓解之需求與後方車流延後之影響中獲得平衡,本研究以透過模式之建構,透過模式之建構與模擬,觀察研究機車停等配置之影響。 而機車左轉待轉區之配置亦影響後方車流之紓解,本模式將左轉之機車視為獨立之流動以考量其停等與延滯特性,為建立衡量整體路口之延滯,本研究針對左轉機車之流動建立二段式左轉機車之延滯模型,使得左轉機車之延滯可被描述於模式中納入最佳化之車流。 本研究利用所發展之號誌模式,進行分析與比較,發現適合之停等區深度配置具有最適之規律,於特定之條件下機車停等區之特定深度可以獲得最佳之紓解效益。本研究透過比較現實配置與模式設計之深度比較分析後,最終本研究建立機車停等區之最適長度之設計流程,以供未來機車停等區之繪製設計予以參考。
Abstract The motorcycle stop zone and the motorcycle left-turn zone are the part of signalized intersection geometric layout. The motorcycle stop zone could separate the motorcycle flow from the car. While motorcycles stop in the intersection, they stop ahead. The motorcycle has high mobility and low start delay. The motorcycle stop zone could provide motorcycle to stop and reduce the conflict between motorcycles and car to developed the efficiency of intersection. The influence by length of motorcycle stop zone is the main topic of research, the most suitable length could balance the stop space of motorcycle and delay of vehicle behind the motorcycle stop zone. This study observed the influence of the motorcycle stop zone by the model building and simulation. The motorcycle left-turn zone also influence the vehicle flow behind it. In the model, the left-turn motorcycle seems as the independence flow to estimate its delay and stop space. To estimate the delay of left-turn motorcycle, this study created a motorcycle left-turn delay model. The intersection signal model would measure the motorcycles’ delay more correctly This study used the signal model to analyze different composition’s situation of vehicle flow and found the rule of most suitable length of motorcycle stop zone which has the better efficiency. This study compared the layout of real world and the output of the model. Finally, this study built the process of compute the motorcycle stop zone and provide a result to refer in practical.
