【摘要】：隨著干線公路里程快速增長和國家高速公路網(wǎng)絡的不斷完善,以及機動車保有量的不斷快速增長,路網(wǎng)負荷日益嚴重。特別是在周末和節(jié)假日期間,交通需求激增,大規(guī)模的集中出行,以及車流高峰持續(xù)時間的延長使節(jié)假日期間干線公路網(wǎng)交通供需矛盾日益嚴重。干線公路網(wǎng)交通擁擠和突發(fā)事件及其引發(fā)的行車安全、運輸效率、能源消耗和環(huán)境污染等問題受到了社會各界的廣泛關注。干線公路網(wǎng)運營管理等工作的實施需要以準確掌握干線公路路網(wǎng)實時運行狀態(tài)及其未來發(fā)展趨勢為基礎和前提。所謂區(qū)域干線公路網(wǎng)交通態(tài)勢評估與分析,就是對某一地區(qū)干線公路網(wǎng)的實時運行狀態(tài)進行分析并預測未來發(fā)展趨勢。分析和預測,其目的是為交通管理者提供科學、有效的途徑掌握干線公路網(wǎng)的交通狀態(tài)和性能,以便其在有限的交通資源條件下,合理分配路網(wǎng)的供給能力。本項研究旨在針對干線公路網(wǎng)日益突出的擁堵和突發(fā)事件頻發(fā)的問題,借鑒國內(nèi)外干線公路運營管理的先進技術(shù)和經(jīng)驗,結(jié)合我國干線公路運營管理的需求,從微觀和宏觀層面,建立多層次關聯(lián)的評估模型,并初步研究建立干線公路網(wǎng)交通運行狀態(tài)發(fā)展趨勢的預測技術(shù)。論文首先以干線公路網(wǎng)交通歷史數(shù)據(jù)為研究對象,根據(jù)路網(wǎng)收費站點信息建立路網(wǎng)模型,開展干線公路網(wǎng)交通特征分析,分析路網(wǎng)網(wǎng)路拓撲結(jié)構(gòu),為后文模型研究提供了基礎和依據(jù)。然后,論文對高速公路歷史OD收費數(shù)據(jù)進行拆分處理,統(tǒng)計出了干線公路網(wǎng)分空間分時段的交通需求,并結(jié)合各路段道路規(guī)劃通行能力推算路段實際通行能力,開展了干線公路網(wǎng)運行狀態(tài)分析。接著,論文根據(jù)路網(wǎng)拓撲結(jié)構(gòu)在計算機上構(gòu)建虛擬路網(wǎng),并將歷史數(shù)據(jù)分時段還原在虛擬路網(wǎng)上,通過軟件模型動態(tài)實時顯示路網(wǎng)狀態(tài)。最后,論文模擬在緊急事件或突發(fā)狀況導致的路段通行能力減弱的情況下,根據(jù)問題路段的交通需求在路網(wǎng)內(nèi)進行交通流重新分配,并對配流后的交通態(tài)勢通過計算機模擬進行評估,構(gòu)建交通突發(fā)事件態(tài)勢評估模型。
[Abstract]:With the rapid growth of highway mileage and the continuous improvement of national highway network, as well as the rapid growth of vehicle ownership, the road network load is becoming increasingly serious, especially during weekends and holidays. The demand for transportation has soared, and there has been a massive concentration of travel. During the holidays, the contradiction between the traffic supply and demand of the trunk highway network becomes more and more serious. The traffic congestion and unexpected events in the trunk highway network and the traffic safety and transportation efficiency caused by it are becoming more and more serious. Energy consumption and environmental pollution have received extensive attention from all walks of life. The implementation of the operation and management of the trunk road network needs to be based on an accurate grasp of the real-time operation state of the trunk road network and its future development trend. The so-called regional trunk road network traffic situation assessment and analysis. It is to analyze the real-time running state of a certain area trunk highway network and predict the future development trend. The purpose of analysis and prediction is to provide science for traffic managers. The effective way to master the traffic state and performance of the trunk highway network, so that it in the limited traffic resources conditions. The purpose of this study is to learn from the advanced technology and experience of domestic and foreign trunk road operation management in view of the increasingly prominent problems of congestion and frequent emergencies in the trunk road network. According to the needs of the operation and management of trunk roads in China, a multi-level related evaluation model is established from the micro and macro levels. At first, the paper takes the historical data of the trunk highway network as the research object, and establishes the road network model according to the network toll station information. The traffic characteristics of trunk highway network are analyzed and the topological structure of highway network is analyzed, which provides the foundation and basis for the later research. Then, the paper divides the historical OD toll data of highway. The traffic demand of the trunk highway network is calculated according to the space and time interval, and the actual capacity of each section is calculated according to the planned capacity of each section. Then, the operation state of the trunk highway network is analyzed. According to the topology of the road network, the paper constructs the virtual road network on the computer, and restores the historical data into the virtual road network in different periods, and displays the road network status dynamically and in real time through the software model. Finally. This paper simulates the traffic flow redistribution in the road network according to the traffic demand of the problem section under the condition that the traffic capacity of the road is weakened due to the emergency or unexpected situation. The traffic situation after distribution is evaluated by computer simulation, and the traffic emergency situation assessment model is constructed.
