【摘要】：交通信息服務系統(tǒng)作為智能交通的一項重要應用,為緩解交通擁堵、改善交通質量、提高交通服務水平作出了重要的貢獻。然而隨著經(jīng)濟社會的快速發(fā)展,現(xiàn)有的交通信息服務機制不能滿足社會公眾對交通信息服務的需求,存在交通信息的綜合處理能力較弱、智能化服務水平較低、交通信息服務方式單一等問題。近年來,車聯(lián)網(wǎng)技術的研究及應用為交通信息服務的發(fā)展提供了新的思路,車聯(lián)網(wǎng)環(huán)境能夠為改善交通信息服務質量創(chuàng)造數(shù)據(jù)條件和基礎平臺,因此構建車聯(lián)網(wǎng)環(huán)境下的新型交通信息服務體系成為當前的研究熱點之一。基于上述背景,論文以車聯(lián)網(wǎng)環(huán)境下的新型交通信息服務協(xié)同體系構建為目標,對車聯(lián)網(wǎng)環(huán)境下交通信息服務協(xié)同關鍵技術展開研究。首先,論文在深入分析車聯(lián)網(wǎng)的技術特征的基礎上,針對交通信息服務的應用需求,提出了一種新型交通信息服務協(xié)同體系,包括交通信息服務模型描述、基于機會通信的服務發(fā)現(xiàn)協(xié)議、基于語義的交通信息服務匹配與服務動態(tài)組合三個部分;其次,在研究Web服務的語法與語義表達技術的基礎上,對交通信息服務的描述方法進行分析,提出應用OWL-S語言建模來實現(xiàn)交通信息服務描述的語義化,并構建了一種基于OWL-S的交通信息服務描述模型;然后,在深入分析Web環(huán)境下服務發(fā)現(xiàn)技術的基礎上,分析了交通信息服務發(fā)現(xiàn)的關鍵內容,并完成了交通信息服務發(fā)現(xiàn)協(xié)議的總體設計,重點研究了車聯(lián)網(wǎng)環(huán)境下的服務請求數(shù)據(jù)分發(fā)過程,即建立機會路由來實現(xiàn)服務請求者與服務提供者之間的數(shù)據(jù)交換;最后,在對服務組合的方法進行研究的基礎上,針對交通信息服務組合的特征,構建了一種基于語義匹配和工作流技術的交通信息服務組合框架,并在該框架下研究了交通信息服務組合的工作流程、服務組合模板的構建方法、原子服務的組合判定方法及交通信息服務的執(zhí)行控制方法。論文提出的車聯(lián)網(wǎng)環(huán)境下的交通信息服務協(xié)同體系能夠有效提升交通信息服務的智能化和個性化水平,增強交通信息服務系統(tǒng)的綜合處理能力,有助于提高交通信息服務系統(tǒng)的服務質量,保障交通運輸?shù)陌踩透咝н\營。
[Abstract]:Traffic information service system, as an important application of intelligent transportation, has made important contributions to alleviate traffic congestion, improve traffic quality and improve traffic service level. However, with the rapid development of economy and society, The existing traffic information service mechanism can not meet the demand of the public for the traffic information service. There are some problems such as the weak comprehensive processing ability of traffic information, the low level of intelligent service, the single mode of traffic information service and so on. The research and application of vehicle networking technology provide a new way of thinking for the development of traffic information service. The vehicle networking environment can create data conditions and basic platform for improving the quality of traffic information service. Therefore, the construction of a new traffic information service system under the vehicle networking environment has become one of the current research hotspots. Based on the above background, the paper aims to build a new traffic information service collaborative system under the vehicle networking environment. The key technologies of traffic information service cooperation under the environment of vehicle networking are studied. Firstly, based on the in-depth analysis of the technical characteristics of vehicle networking, the paper aims at the application needs of traffic information service. A new traffic information service collaborative system is proposed, which includes three parts: traffic information service model description, service discovery protocol based on opportunity communication, semantic traffic information service matching and service dynamic composition. On the basis of studying the syntax and semantic expression technology of Web service, the description method of traffic information service is analyzed, and OWL-S language modeling is proposed to realize the semantic description of traffic information service. A description model of traffic information service based on OWL-S is constructed, and then the key content of traffic information service discovery is analyzed on the basis of deeply analyzing the technology of service discovery in Web environment. The overall design of the traffic information service discovery protocol is completed, and the process of service request data distribution under the environment of vehicle network is studied, which is to establish the opportunity route to realize the data exchange between the service requestor and the service provider. Based on the research of service composition method and the characteristics of traffic information service composition, a framework of traffic information service composition based on semantic matching and workflow technology is constructed. Under this framework, the workflow of traffic information service composition and the construction method of service composition template are studied. In this paper, the cooperative system of traffic information service under the environment of vehicle networking can effectively improve the intelligence and individuation level of the traffic information service, which is based on the combination and decision method of atomic service and the execution control method of traffic information service. Enhancing the comprehensive processing ability of the transportation information service system is helpful to improve the service quality of the traffic information service system and ensure the safe and efficient operation of the transportation.
