中文摘要:
      為了解決“一路一線”模式的換乘問題,提出了一種十字路口布局及其相位方案。設置了左轉、直行、右轉和公交4種進口道,并將右轉車流納入統一控制。??空驹O置在公交進口道邊和出口道邊,公交車通過路口時分別???個站,換乘不過斑馬線,可以實現換乘方便、快捷,并分散客流,避免擁擠。使用4相位動態配時方案,每個相位通過5股車流和1股行人交通流,同一股右轉車流在一個相位周期內被放行2次,相位內的交通流無沖突,而且行人、右轉車流和非機動車三者之間也沒有相互沖突,提高了安全性。對換乘時間進行了詳細分析,說明了在某些特定條件下換乘比不換乘更省時間,提出了紅燈效應和擁堵效應等概念。對通行能力進行了初步分析,結果表明該布局可以提高通行能力。
英文摘要:
      This paper put forward a intersection layout and its traffic signal phase design in order to solve the problem of transfer based on the “one road one line” mode. It set four kinds of approaches that included the left-turn approach, the straight approach, the right-turn approach and the bus approach, and the right-turn traffic flows ware controlled uniformly. The bus stations are located at the edges of the bus lane upstream and the bus lane downstream. Bus stop at two bus stations respectively through a intersection, and when passengers change, don’t pass through zebra crossings, the layout is fast and convenient to transfer, and can disperse passenger flows, and avoid congestion. Four phase dynamic timing scheme was used, there were five traffic flows and one pedestrian flow each phase, and the same right-turn traffic was passed two times in one phase cycle, there were not traffic flow conflicts in each phase, and there were all no conflicts between the right-turn traffic, pedestrians flows, and non-motor vehicles flows, and the security is improved. Transfer time was analyzed in detail, it is concluded that transfer is better than no transfer to save time in some of the special conditions, and put forward a few of new concepts, such as the red light effect and the congestion effect, and so on. Traffic capacity was analyzed preliminary, the results show that the layout can improve traffic capacity.
