【摘要】：高速公路作為連接城市的主要道路,對促進國民經(jīng)濟的發(fā)展起著非常重要的作用。自改革開放以來,我國的高速公路事業(yè)發(fā)展迅速。在過去的幾十年里,我國高速公路通車總里程已超過美國,居世界第一位。盡管高速公路里程在不斷增加,但是在高速公路管理技術(shù)上我國與西方發(fā)達國家仍有一段距離,尚難以滿足經(jīng)濟快速發(fā)展的需要。節(jié)假日期間,車輛大量涌入高速公路,就會造成擁堵甚至堵塞,大大降低了高速公路的通行效率和安全性。因此,保持高速公路的安全與暢通,不僅關(guān)系到人們的日常出行,而且對我國經(jīng)濟的長遠發(fā)展有非常直接的影響。通過分析國內(nèi)外相關(guān)研究資料,可以發(fā)現(xiàn),建立智能交通系統(tǒng)(Intelligent Transport System,ITS)是保護公路暢通、安全的非常有效的方式。本文基于地理信息系統(tǒng)(Geographic Information System,GIS)的發(fā)展現(xiàn)狀,結(jié)合交通流誘導系統(tǒng)在國內(nèi)外高速公路的綜合經(jīng)營狀況,在應(yīng)用地理信息系統(tǒng)技術(shù)的基礎(chǔ)上,分析、設(shè)計適合我國高速公路交通流的誘導系統(tǒng)的框架,并對其中的一些關(guān)鍵問題進行了研究。在本文中,筆者使用收集到的數(shù)據(jù)進行驗證,為Petri網(wǎng)的交通流(CPN)模式提供了理論依據(jù),通過研究道路網(wǎng)絡(luò)的拓撲結(jié)構(gòu),分析信息傳遞的原則,建立了C#和CPN模型之間的通信機制。此外,本研究還設(shè)計了應(yīng)急預案,并對應(yīng)急響應(yīng)進行了較為深入的研究:利用開放的XML技術(shù)建立數(shù)字化應(yīng)急預案,進而結(jié)合地理信息系統(tǒng),做到用圖文并茂的方式和互動的形式來展現(xiàn)應(yīng)急預案。在綜合研究的基礎(chǔ)上,本文設(shè)計了基于地理信息系統(tǒng)的高速公路交通流誘導系統(tǒng),其目的是實現(xiàn)信息查詢的共享,展示真實的實時路況,設(shè)計最優(yōu)的路線指引,從而幫助車輛更有效地利用高速道路資源,使交通運行系統(tǒng)更加優(yōu)化。
[Abstract]:Expressway, as the main road connecting city, plays a very important role in promoting the development of national economy. Since the reform and opening up, the cause of expressway in China has developed rapidly. In the past few decades, the total mileage of freeway opening in China has surpassed that of the United States and ranked first in the world. Although highway mileage is increasing continuously, there is still a distance between China and western developed countries in highway management technology, which is still difficult to meet the needs of rapid economic development. During the holidays, a large number of vehicles pour into the freeway, which will cause congestion or even congestion, greatly reducing the efficiency and safety of the highway. Therefore, to maintain the safety and smooth of freeway is not only related to people's daily travel, but also has a very direct impact on the long-term economic development of our country. By analyzing the relevant research data at home and abroad, it can be found that the establishment of intelligent transportation system (Intelligent Transport System,ITS) is a very effective way to protect highway smooth and safe. Based on the development of (Geographic Information System,GIS (Geographic Information system), combined with the comprehensive operation of traffic flow guidance system in expressway at home and abroad, this paper analyzes the application of GIS technology. The frame of the guidance system for freeway traffic flow in China is designed, and some key problems are studied. In this paper, the author uses the collected data to verify, which provides a theoretical basis for the traffic flow (CPN) model of Petri network. By studying the topological structure of road network, the principle of information transmission is analyzed. The communication mechanism between C # and CPN model is established. In addition, this study also designs the emergency plan, and carries on the comparatively thorough research to the emergency response: using the open XML technology to establish the digitized emergency plan, and then unifies the geographic information system, Make use of picture and text of the way and interactive form to show the emergency plan. On the basis of comprehensive research, this paper designs a freeway traffic flow guidance system based on GIS. The purpose of this system is to realize the sharing of information query, to show the real time road conditions, and to design the best route guidance. Thus, it helps vehicles to make more efficient use of high-speed road resources and makes traffic operation system more optimized.
