摘要:随着交通工具的快速发展和人们生活的提高,家用车越来越多,随之而来的是道路负载量也在日益增加,城市的交通拥堵也越来越严重。交通控制也变得越发重要了,引发了人们对交通控制的重视,加强了对交通管理的研究及探讨。本论文简单的介绍了智能交通系统的发展史和车载电子标签的原理,并构建以单交叉口为模型的交通优先控制系统。 通过相关理论和资料,建立相关交通模型,提出其求解算法,并将模型与算法应用到一个简化的交通网络中去。并且在Visual Basic平台下进行相关优先级控制程序的开发,实现编程以控制交通的优先级判别,同时为了使仿真效果更为贴近于现实,采用交通流仿真工具VISSIM仿真软件。22748 实践证明,利用VISSIM与VB语言平台搭建实现对十字路口信号灯进行优先级控制的系统,从而体现了仿真模型的合理性和所开发软件模块的可靠性,提供了一个解决突发性交通事件的有效方法。 毕业论文关键词: 优先控制系统;车载电子标签;优先级判别;VISSIM Design and Simulation of Priority Intersection Control System Based on Vehicle Electronic Tags Abstract: With the rapid development of transport and improve people's lives, more and more private cars, followed by a load of road are also increasing urban traffic congestion has become increasingly serious. Traffic control is becoming increasingly important, and sparked the importance of traffic control, and strengthen the research and discussion of traffic management. In this paper, a brief history of the development of the principles of smart electronic tags with car transportation, and build a model of a single intersection traffic priority control systems. Through theory and data, establish relevant traffic model, proposed their algorithm and model and algorithm applied to a simplified network traffic to go. And development programs related to priority control in Visual Basic platform, programmed to determine the priority of traffic control, but in order to make the simulation results closer to reality, using traffic simulation software VISSIM simulation tools. Practice has proved that the use of VISSIM platform built with VB language to achieve a crossroads lights for priority control system, which reflects the rationality of the simulation model and the reliability of software modules developed to provide a solution to unexpected traffic events effectively methods.
