【摘要】：随着社会的不断进步,人们生活质量的提高,城市里的汽车拥有量也在逐年增多,而现有的交通基础设施已无法满足需求,于是引发了严重的交通拥堵,能源浪费,以及大量的汽车尾气排放给城市空气造成的污染,甚至引发雾霾。目前常用城市路口交通控制模式相对简单,在面对愈发复杂的路况时越来越难以应付,这种情况亟待解决。本课题针对目前的城市里多变复杂的交通状况,提出了一套以RFID技术为基础的智能交通系统方案,并完成了对这款能更好适应我国交通特点的智能交通信号控制器的设计工作。该控制器以RFID为技术基础,建立在ARM9平台之上,具有模块化、可移植、易扩展、方便升级维护、具有实时多任务处理能力等特点。完成了信息采集、数据处理、控制策略生成等一系列功能模块的软硬件设计,并且提出了一种全新的城市交通干线双向绿波带算法,使进入主干道的车辆上行和下行一路绿灯。本课题主要内容结构概括如下：首先,概述了智能交通控制器的概念及其发展历史,分析国内外目前比较流行的几套交通控制器的优缺点。其次,根据我国城市交通特点,在现有技术的基础之上设计了一套基于RFID技术的车辆信息检测器,结合了多相位智能交通控制器组成了文中提出的新型智能交通控制器。该控制器灵活多变,可任意拓展升级,用户可以根据本地的实际需要,构建出一套既符合当前需求又有利于长远发展的系统。最后,对现有的一些常用交通控制算法的优缺点进行了分析,并在其基础上提出了一种新型的交通干线双向绿波带的算法,该算法利用左转相位“迟起”和“早断”,使上行和下行相协调。能显著降低车辆停车延误时间,整个城市的交通状况都将获得改善。
[Abstract]:With the continuous progress of society and the improvement of people's quality of life, the number of cars in the city is increasing year by year, and the existing transportation infrastructure can no longer meet the demand, thus causing serious traffic congestion and energy waste. And a large number of vehicle exhaust emissions to urban air pollution, and even lead to haze. At present, the traffic control mode of urban intersections is relatively simple, and it is more and more difficult to deal with in the face of increasingly complex road conditions, which needs to be solved urgently. In view of the changeable and complex traffic situation in the city at present, this paper puts forward a set of intelligent transportation system scheme based on RFID technology, and completes the design of the intelligent traffic signal controller which can better adapt to the traffic characteristics of our country. The controller is based on RFID and is built on the ARM9 platform. It is modular, portable, easy to expand, easy to upgrade and maintain, and has the ability of real-time multi-task processing. The software and hardware design of a series of function modules, such as information collection, data processing, control strategy generation and so on, are completed, and a new bidirectional green wave band algorithm for urban traffic trunk lines is proposed to make the green light of the upstream and downlink routes of the vehicles entering the main road. The main content structure of this topic is summarized as follows: Firstly, the concept of intelligent traffic controller and its development history are summarized, and the advantages and disadvantages of several sets of traffic controllers which are popular at home and abroad are analyzed. Secondly, according to the characteristics of urban traffic in China, a set of vehicle information detector based on RFID technology is designed based on the existing technology, and a new type of intelligent traffic controller based on multi-phase intelligent traffic controller is proposed in this paper. The controller is flexible and flexible, can be expanded and upgraded arbitrarily, and users can build a set of systems that not only meet the current needs but also benefit the long-term development according to the actual local needs. Finally, the advantages and disadvantages of some commonly used traffic control algorithms are analyzed, and on the basis of these algorithms, a new bidirectional green wave band algorithm for traffic trunk lines is proposed, which uses the left turn phase "late rise" and "early break". Coordinate up and down. A significant reduction in vehicle parking delays will improve traffic conditions throughout the city.
