【摘要】：作为路网中的常发交通瓶颈点,交叉口的治理改造问题一直都是交通工程研究的热点。国内外针对单交叉口的设计方法已经比较成熟,但是随着城市路网规模的不断扩大,交通行为的日益多样化,路网中短距离相邻交叉口中的交通流往往会相互干扰,并因为疏导不畅而造成拥堵的现象屡见不鲜。因此,论文将城市路网中短距相邻平面信号双交叉口的协同优化设计作为主要研究内容,通过分析其导致交通拥堵的主要原因,提出了信号双交叉口相关参数的设计方法,并给出了优化设计的评价模型。具体而言,论文完成了如下工作：首先,论文对平面信号双交叉口的交通流特性进行了研究,给出了可能导致交通拥堵的主要原因：其次,论文提出了平面信号双交叉口间交通流状态的评价指标,并因此给出相关的评价方法；然后,面向交通拥堵缓解目标,论文给出了平面信号双交叉口的优化设计方法,提出了相关原则,并对其中的主要参数进行了优化分析。最后,结合某城市道路网络中的平面双交叉口案例进行了设计和评价。论文的创新点主要有：提出了面向平面双交叉口的综合评价体系；其次,相比以往对城市双交叉口某个或者某两个方面的优化研究,在此给出了一个比较完善的多因素的整体优化设计方案。论文所做的研究成果可以为城市双交叉口或连续交叉口的规划和改进性建设提供参考,有一定的现实作用。
[Abstract]:As a common traffic bottleneck in road network, the problem of intersection governance and reconstruction has always been a hot spot in traffic engineering research. Domestic and foreign design methods for single intersection have been more mature, but with the continuous expansion of the scale of urban road network, traffic behavior is increasingly diversified, traffic flow in the road network in short distance adjacent intersections often interfere with each other. And the phenomenon of congestion caused by poor diversion is common. Therefore, the paper takes the coordinated optimization design of the short distance adjacent signal double intersection in the urban road network as the main research content. By analyzing the main causes of the traffic jam, the paper puts forward the design method of the related parameters of the signal double intersection. The evaluation model of optimal design is given. Specifically, the thesis has completed the following work: First of all, the paper studies the traffic flow characteristics of the plane signal dual intersection, and gives the main causes of traffic congestion. Secondly, the paper puts forward the evaluation index of the traffic flow state between the plane signal double intersection. Then, aiming at the goal of traffic congestion alleviation, the paper gives the optimization design method of plane signal dual intersection, puts forward the relevant principles, and optimizes the main parameters. Finally, the design and evaluation of a city road network in the case of dual intersection are carried out. The main innovations of this paper are as follows: a comprehensive evaluation system oriented to two intersections is put forward. Secondly, compared with the previous research on one or two aspects of urban double intersections, In this paper, a more perfect multi-factor overall optimal design scheme is presented. The research results can provide a reference for the planning and improvement of urban double intersection or continuous intersection.
