This paper is intended to improve the performance of signalized intersections, one of the most important systems of traffic control explained within the scope of smart transportation systems. These structures, which have the main role in ensuring the order and flow of traffic, are alternative systems depending on the different methods and techniques used. Determining the operation principles of these systems requires an extremely careful and planned study, considering their important role. Performance outputs obtained from the queue analyses made in previous studies formed the input of this study. The most important techniques are used in the effective control of intersections, such as signal timing: in particular, the use of effective green time and order of the transitions between phases. In this research, a traffic-sensitive signalized intersection control system was designed with the suggested methods against these two problems. The sample intersections were selected from three cities with the highest population density as the case study area. In the analysis of the performance of the connection arms of the selected intersections, flow intensity data were taken into consideration, as well as the arrival and service rates. Based on this, the outputs of the two proposed models regarding the use of phase transitions and effective green durations were compared with two other adaptive control systems and their positive results were shared. The results showed that signalized intersections, operating with a well-planned and correctly chosen technique, better regulate density and queuing.

智能城市和智能交通系统的数据分析:用于在信号化交叉口安排阶段和交通灯的分析模型

本文旨在提高信号交叉口的性能,这是智能交通系统范围内解释的最重要的交通控制系统之一。这些结构在确保交通秩序和流动方面起主要作用,是取决于所使用的不同方法和技术的替代系统。考虑到它们的重要作用,确定这些系统的操作原理需要非常仔细和有计划的研究。从先前研究中进行的队列分析中获得的性能输出构成了本研究的输入。最重要的技术用于交叉口的有效控制,例如信号时序:特别是有效绿灯时间的使用和阶段之间的转换顺序。在这项研究中,针对这两个问题,采用建议的方法设计了交通敏感的信号交叉口控制系统。样本路口选取人口密度最高的三个城市作为案例研究区。在分析所选交叉口连接臂的性能时,考虑了流量强度数据,以及到达和服务率。在此基础上,将关于使用相变和有效绿色持续时间的两个建议模型的输出与其他两个自适应控制系统进行了比较,并分享了它们的积极结果。结果表明,采用精心规划和正确选择的技术运行的信号交叉口可以更好地调节密度和排队。
