【摘要】：随着机动车交通负荷水平的整体提高,环形交叉口存在交通事故频发、通行效率低下、行人和非机动车过街难等交通问题。挖掘和发挥环形交叉口作为一种交通设施的服务能力,对于一个城市或区域的文化保护和传承具有十分重要的意义。首先,选取典型的环形交叉口,从制高点拍摄的现场影像中分析得知,错误的车道选择行为在我国具有普遍性,因此,有效引导驾驶员的车道选择行为是减少环形交叉口的交通冲突、规范环形交叉口的车辆运行秩序、有效避免交通事故的可行措施。其次,针对两种常用的环形交叉口机动车交通流向调查方法进行了对比分析,建立了一种工作强度低、调查准确度高、易在工程实践中推广应用的环道基本断面法。然后,利用非优化建模的思想,建立了基于非等饱和度原则的预设时间全控制方法,该方法能够有效遏制机动车交通高峰时段环形交叉口的整体性能发生显著恶化；建立了基于进口道阻塞成因分析的交通响应进口道控制方法,该方法在一定机动车交通负荷水平区间下,可有效的避免或延迟环道死锁时刻；建立了基于通行时空资源利用率的交通响应全控制方法,单进口轮流放行和多进口同步放行两种方式均能满足环形交叉口较大区间范围的机动车交通负荷水平,但是,多进口同步放行方式在同等条件下要优于单进口轮流放行方式。
[Abstract]:With the overall improvement of vehicle traffic load, there are many traffic problems such as frequent traffic accidents, low traffic efficiency and difficulty for pedestrians and non-motor vehicles to cross the street at roundabout intersection. It is of great significance for a city or region to protect and inherit the culture of a city or a region by excavating and exerting the service ability of a circular intersection as a traffic facility. First of all, select the typical roundabout, from the scene image taken from the commanding height, we know that the wrong lane selection behavior is common in our country, so, It is a feasible measure to effectively guide the driver's lane selection behavior to reduce traffic conflicts, standardize the running order of vehicles and avoid traffic accidents. Secondly, by comparing and analyzing two common methods of investigation on traffic direction of circular intersection, a basic section method is established, which is easy to be popularized in engineering practice and has low working intensity, high investigation accuracy and easy to be popularized and applied in engineering practice. Then, using the idea of non-optimal modeling, a preset time full control method based on the principle of non-equal saturation is established, which can effectively restrain the deterioration of the overall performance of the annular intersection in the peak period of vehicle traffic. The traffic response control method based on the analysis of the cause of the entrance road congestion is established. The method can effectively avoid or delay the deadlock time of the annular road in a certain vehicle traffic load level range. A traffic response control method based on the utilization ratio of traffic space and time resources is established. Both single inlet rotation release and multiple inlet synchronous release can meet the traffic load level of large range of motor vehicles at roundabout. Multi-import synchronous release mode is better than single import rotation release mode under the same conditions.
