【摘要】：隨著社會(huì)的不斷進(jìn)步,人們生活質(zhì)量的提高,城市里的汽車擁有量也在逐年增多,而現(xiàn)有的交通基礎(chǔ)設(shè)施已無(wú)法滿足需求,于是引發(fā)了嚴(yán)重的交通擁堵,能源浪費(fèi),以及大量的汽車尾氣排放給城市空氣造成的污染,甚至引發(fā)霧霾。目前常用城市路口交通控制模式相對(duì)簡(jiǎn)單,在面對(duì)愈發(fā)復(fù)雜的路況時(shí)越來(lái)越難以應(yīng)付,這種情況亟待解決。 本課題針對(duì)目前的城市里多變復(fù)雜的交通狀況,提出了一套以RFID技術(shù)為基礎(chǔ)的智能交通系統(tǒng)方案,并完成了對(duì)這款能更好適應(yīng)我國(guó)交通特點(diǎn)的智能交通信號(hào)控制器的設(shè)計(jì)工作。該控制器以RFID為技術(shù)基礎(chǔ),建立在ARM9平臺(tái)之上,具有模塊化、可移植、易擴(kuò)展、方便升級(jí)維護(hù)、具有實(shí)時(shí)多任務(wù)處理能力等特點(diǎn)。完成了信息采集、數(shù)據(jù)處理、控制策略生成等一系列功能模塊的軟硬件設(shè)計(jì),并且提出了一種全新的城市交通干線雙向綠波帶算法,使進(jìn)入主干道的車輛上行和下行一路綠燈。 本課題主要內(nèi)容結(jié)構(gòu)概括如下： 首先,概述了智能交通控制器的概念及其發(fā)展歷史,分析國(guó)內(nèi)外目前比較流行的幾套交通控制器的優(yōu)缺點(diǎn)。 其次,根據(jù)我國(guó)城市交通特點(diǎn),在現(xiàn)有技術(shù)的基礎(chǔ)之上設(shè)計(jì)了一套基于RFID技術(shù)的車輛信息檢測(cè)器,結(jié)合了多相位智能交通控制器組成了文中提出的新型智能交通控制器。該控制器靈活多變,可任意拓展升級(jí),用戶可以根據(jù)本地的實(shí)際需要,構(gòu)建出一套既符合當(dāng)前需求又有利于長(zhǎng)遠(yuǎn)發(fā)展的系統(tǒng)。 最后,對(duì)現(xiàn)有的一些常用交通控制算法的優(yōu)缺點(diǎn)進(jìn)行了分析,并在其基礎(chǔ)上提出了一種新型的交通干線雙向綠波帶的算法,該算法利用左轉(zhuǎn)相位“遲起”和“早斷”,使上行和下行相協(xié)調(diào)。能顯著降低車輛停車延誤時(shí)間,整個(gè)城市的交通狀況都將獲得改善。
[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.
