【摘要】：無信號控制交叉口是各個方向的車流相交匯之處，對整個城市道路網(wǎng)的運作產(chǎn)生很大的影響。因為車流的轉向會引起機動車，非機動車和行人之間的沖突，混合交通比較嚴重，造成了交叉口處復雜的局面。無信號交叉口混合交通流的相互影響及對交叉口通行能力的影響成為城市道路網(wǎng)研究的難點。 國內(nèi)外交通工作者研究主路優(yōu)先交叉口通行能力時，很少考慮到行人和非機動車對機動車產(chǎn)生的影響，通行能力的計算存在不符合實際的問題。論文基于我國城市道路網(wǎng)交通條件及交叉口處混合交通現(xiàn)象明顯的現(xiàn)狀，結合現(xiàn)有研究方法的不足，綜合考慮行人和非機動車對機動車的影響，提出當量人群流的概念，并對各向機動車流，當量人群流在交叉口處產(chǎn)生的沖突點進行詳細劃分，引入沖突技術法進行分析確定交通流優(yōu)先等級，提出橫穿主支路過街的當量人群流的優(yōu)先等級關系，，分別建立各向機動車流通過交叉口時產(chǎn)生的多個沖突點處通行能力計算模型，同時設計了主路和支路右轉車流不受當量人群流影響和受當量人群流影響時通行能力的計算公式。最后，以462型交叉口為例，通過實例分析，給出了模型中各參數(shù)的建議值，并驗證了模型的有效性。在分析中考慮了當量人群流的影響，相比于一般的忽略我國交叉口混合交通流復雜現(xiàn)狀的計算方法，該方法更符合城市道路交叉口的實際情況，具有更高的理論意義和實用價值。
[Abstract]:Unsignalized intersection is the intersection of traffic flow in all directions, which has a great influence on the operation of the whole urban road network. Because of the conflict between vehicle, non-motor vehicle and pedestrian caused by the turning of the traffic flow, the mixed traffic is serious, resulting in the complex situation at the intersection. The interaction of mixed traffic flow at unsignalized intersections and its influence on the capacity of intersections have become the difficulties in the study of urban road network. When the traffic workers at home and abroad study the capacity of priority intersections of main roads, the influence of pedestrians and non-motor vehicles on motor vehicles is seldom taken into account, and the calculation of traffic capacity does not accord with the actual problems. Based on the traffic conditions of urban road network in China and the obvious situation of mixed traffic at intersections, combined with the deficiency of existing research methods, this paper puts forward the concept of equivalent crowd flow by considering the influence of pedestrians and non-motor vehicles on motor vehicles. At the same time, the conflict points produced by vehicle flow and equivalent crowd flow in each direction are divided in detail. The conflict technique is introduced to analyze and determine the priority grade of traffic flow, and the priority grade relationship of equivalent crowd flow across the main branch road is put forward. The calculation models of traffic capacity at several conflict points are established respectively when the vehicle flow in each direction passes through the intersection. At the same time, the formulas for calculating the capacity of the right-turn traffic on the main road and the branch road without the influence of the equivalent crowd flow and the influence of the equivalent crowd flow are designed. Finally, taking the 462 intersection as an example, the suggested values of each parameter in the model are given through an example analysis, and the validity of the model is verified. The effect of equivalent crowd flow is considered in the analysis. Compared with the general calculation method which ignores the complex situation of the mixed traffic flow at intersections in our country, the method is more suitable for the actual situation of urban road intersections. It has higher theoretical significance and practical value.
