【摘要】：随着我国经济的快速发展,机动车的保有量迅速上升,交通需求普遍增长,随之而来的交通问题带来了能源的浪费,城市效率的降低,也造成了严重的噪声污染和空气污染。随着中国城市建设的步步的完善,重视对交通问题的研究,做好交通规划,避免重复建设,构建合理的城市布局,对我国的城市长远发展有非常重要的意义。本文研究微观交通仿真领域交叉口的运行情况。交叉口在交通网络中处于枢纽的位置,交通问题多发,如果运行不畅的话,很容易造成交通堵塞,降低交通效率。因此,通过对交叉口进行渠化和信号配时优化,使得交叉口的通行能力得到提高,具有重要的现实意义。本文介绍了了近些年国内和国外在微观交通仿真方面的主要的研究阶段、研究内容、取得的成果以及对主流的交通仿真软件进行了简单的介绍。本文选用微观仿真软件VISSIM来对交叉口进行模拟仿真,介绍了对交叉口进行优化的两种方法,渠化和信号配时优化。在信号配时优化部分,选取了优化配时软件Synchro进行优化配时,设计出更好的方案,然后将优化后的方案带入到VISSIM模型中进行验证,确保优化措施有效。最后进行实证研究,选取北京市典型的交叉口大望桥交叉口进行模拟仿真,提出优化措施。通过本次仿真使得北京市的交通路网能够更加有效的运转,体现了交通仿真的研究价值和重要意义。
[Abstract]:With the rapid development of China's economy, the number of motor vehicles has increased rapidly, and the traffic demand has generally increased. The traffic problems brought along with it have brought about the waste of energy, the reduction of urban efficiency, and the serious noise pollution and air pollution. With the improvement of urban construction in China, it is of great significance for the long-term development of Chinese cities to pay attention to the study of traffic problems, to do well traffic planning, to avoid repeated construction and to construct a reasonable urban layout. This paper studies the operation of intersection in microscopic traffic simulation field. Intersection in the traffic network in the hub position, traffic problems, if the operation is not smooth, it is easy to cause traffic congestion and reduce traffic efficiency. Therefore, it is of great practical significance to improve the traffic capacity of intersections through channelization and signal timing optimization. This paper introduces the main research stages, research contents, achievements and the main software of traffic simulation in recent years, both at home and abroad. In this paper, the micro simulation software VISSIM is used to simulate and simulate the intersection, and two methods of optimizing the intersection are introduced, which are channelization and signal timing optimization. In the part of signal timing optimization, the optimal timing software Synchro is selected to optimize the timing, and a better scheme is designed, and then the optimized scheme is brought into the VISSIM model for verification to ensure the effectiveness of the optimization measures. Finally, empirical research is carried out, and the typical intersection of Dawangqiao in Beijing is selected to simulate and simulate, and the optimization measures are put forward. Through this simulation, the traffic network in Beijing can run more effectively, which reflects the research value and significance of traffic simulation.
