【摘要】：平面交叉是路网交通的关键节点,而高效的交通组织方式是提高平面交叉运行效率的重要手段。在国外发达国家,新型平面交叉越来越得到政府部门重视。新型平面交叉的优化设计方案在帮助减少交通建设投资的同时还可以增加道路通行能力和安全性。而我国对新型平面交叉的研究却很少,对新型平面交叉的设计、应用和评价方面都还处于初步阶段,与国外发达国家差距较大。而新型平面交叉有着提高平面交叉通行能力,增加道路安全性,缩减建设投资等诸多优点。因此研究新型平面交叉对缓解我国交通拥堵现状有重大意义。论文通过对国外的五种新型平面交叉设计形式及交通组织方式进行分析,并将其与传统十字型平面交叉做对比,列举分析其优、劣势所在,为交通规划者和道路设计者解决交通拥堵问题提供新的思路;结合排队理论、车辆侧向安全宽度、自由车流换道轨迹等理论基础,建立左转漂移平面交叉相关技术指标计算模型并利用模型给出左转漂移车道长度、宽度、与引道合理间距等建议值;根据左转漂移平面交叉交通流特性,提出左转漂移平面交叉相位设计方案,建立左转漂移平面交叉信号配时模型,并基于绿波交通流优化信号配时方案;最后通过建立左转漂移平面交叉和传统十字型平面交叉的交通仿真模型,选取排队长度,停车次数,车辆延误等关键评价指标进行对比分析,证明了左转漂移平面交叉的运行优越性。
[Abstract]:Plane crossing is the key node of road network traffic, and efficient traffic organization is an important means to improve the efficiency of plane crossing operation. In foreign developed countries, the new plane intersection has been paid more and more attention by government departments. The new optimal design scheme of plane intersection can help to reduce the investment in traffic construction and increase the capacity and safety of the road at the same time. However, there are few researches on the new plane intersection in our country. The design, application and evaluation of the new plane intersection are still in the initial stage, which is far from the developed countries. The new plane crossing has many advantages, such as improving the capacity of plane crossing, increasing road safety, reducing construction investment and so on. Therefore, it is of great significance to study the new plane intersection to alleviate the current situation of traffic congestion in China. Through the analysis of five new types of plane cross design and traffic organization abroad, the paper compares them with the traditional cross plane, and enumerates its advantages and disadvantages. It provides a new way of thinking for traffic planners and road designers to solve the problem of traffic congestion, combining with the queuing theory, the lateral safe width of vehicles, the free traffic path changing, and so on. The model of cross correlation technical index of left drift plane is established, and the suggested values such as length, width and reasonable distance between left drift lane and approach road are given by using the model, and according to the characteristics of cross traffic flow in left drift plane, The design scheme of cross phase of left turn drift plane is put forward, and the time model of cross signal of left turn drift plane is established, and the signal timing scheme is optimized based on green wave traffic flow. Finally, the traffic simulation models of left-turn drift plane crossing and traditional cross-plane crossing are established, and the key evaluation indexes, such as queue length, parking times, vehicle delay and so on, are compared and analyzed. It is proved that the crossing of the left turn drift plane is superior.
