鑒於以往公車優先號誌之控制策略,大都以單一路口號誌來設計,雖可在適當的狀況下提升公車通過單一路口之效率,但在幹道或路網號誌連鎖控制下,這些單一路口公車優先的號誌控制策略勢必會造成車輛在群組路口續進的衝擊,甚至破壞連鎖,因此有必要進一步針對連鎖號誌時制設計下公車優先號誌的邏輯加以分析探討。本研究結合號誌時制設計軟體Synchro與Microsoft Office Excel之應用,設計虛擬路網之十二種幹道連鎖號誌時制情境,並模擬分析不同公車優先號誌控制策略之影響。研究結果顯示,不執行公車優先號誌策略與執行公 Most bus priority signal control strategies are conducted at a single intersection. Although they can improve the efficiency of buses which are approaching a signal controlled intersection under some conditions, they also might corrupt the coordination of
