【摘要】：隨著中國經(jīng)濟(jì)的發(fā)展,城鎮(zhèn)化進(jìn)程加快,城市人口快速增長,機(jī)動車保有量也越來越大,城市道路的建設(shè)速度已難以滿足城市居民正常的交通需求。目前,人口集中的大城市各類突發(fā)事件頻出,嚴(yán)重危及人們生命財(cái)產(chǎn)的安全和未來城市的健康發(fā)展,研究突發(fā)事件的相關(guān)理論和應(yīng)對方法已成為當(dāng)務(wù)之急。城市交通突發(fā)事件多發(fā),尤其是干道交通突發(fā)事件,具有破壞性大、影響范圍廣等特點(diǎn),對城市交通系統(tǒng)的運(yùn)行影響巨大。為了更加科學(xué)有效地處理城市干道交通突發(fā)事件,有必要針對突發(fā)交通事件的影響和應(yīng)急救援疏導(dǎo)進(jìn)行研究。論文對比分析了一般突發(fā)事件和交通突發(fā)事件的相關(guān)理論,明確了城市交通突發(fā)事件對城市交通系統(tǒng)產(chǎn)生的影響�；诮煌ㄍ话l(fā)事件條件下對交通流特性和路網(wǎng)可靠性的研究,從通行能力、車輛延誤、二次事故及服務(wù)水平等四個(gè)方面對城市干道交通突發(fā)事件的道路影響進(jìn)行分析。同時(shí),考慮救援實(shí)施的交通影響,得出事件交通影響范圍的確定方法,為建立應(yīng)急疏散模型提供了先決條件。然后,在對常規(guī)交通組織方法研究的基礎(chǔ)上,歸納總結(jié)出適用于城市干道交通突發(fā)事件的應(yīng)急組織方法和智能交通組織體系,并通過對一般交通疏導(dǎo)模型的改進(jìn),建立兼顧救援與疏導(dǎo)的應(yīng)急疏散模型,保障應(yīng)急交通組織的科學(xué)與高效。此外,選取影響范圍、事發(fā)位置、事發(fā)時(shí)間等作為評判指標(biāo),運(yùn)用模糊綜合評價(jià)法對事件的應(yīng)急等級進(jìn)行判定,并根據(jù)應(yīng)急等級制定相應(yīng)的組織預(yù)案,為交通應(yīng)急管理部門快速處置交通突發(fā)事件提供科學(xué)有效的方法。最后,論文假設(shè)重慶市江北區(qū)嘉州路某處發(fā)生公交車自燃,根據(jù)研究對事件實(shí)施應(yīng)急交通組織,并通過仿真軟件對組織方案實(shí)施的效果和可行性進(jìn)行驗(yàn)證。本文將城市干道交通突發(fā)事件作為研究對象,建立兼顧救援與疏導(dǎo)的應(yīng)急疏散模型,并提出事件應(yīng)急等級的判定方法,制定相應(yīng)等級的組織預(yù)案,以提高交通管理部門應(yīng)對城市干道交通突發(fā)事件的應(yīng)急組織管理能力和決策水平。
[Abstract]:With the development of China's economy, the acceleration of urbanization, the rapid growth of urban population, and the increasing number of motor vehicles, the speed of urban road construction has been difficult to meet the normal traffic needs of urban residents. The occurrence of all kinds of unexpected events in large cities with concentrated population seriously endangers the safety of people's life and property and the healthy development of future cities. It has become an urgent matter to study the relevant theories and coping methods of emergencies. Urban traffic emergencies, especially the main road traffic emergencies, have the characteristics of large destruction and wide range of influence. It has a great impact on the operation of urban traffic system. In order to deal with urban traffic emergencies more scientifically and effectively. It is necessary to study the impact of traffic emergencies and emergency rescue guidance. Based on the study of traffic flow characteristics and road network reliability under the condition of traffic emergencies, traffic capacity and vehicle delay are studied. The second accident and service level are four aspects to analyze the road impact of urban trunk road traffic emergencies. At the same time, considering the traffic impact of rescue implementation, the method of determining the traffic impact range of the incident is obtained. The precondition is provided for the establishment of emergency evacuation model. Then, based on the study of the conventional traffic organization method. Summarize the emergency organization method and intelligent traffic organization system suitable for urban trunk road traffic emergencies, and through the improvement of the general traffic diversion model, establish the emergency evacuation model which takes both rescue and guidance into account. In addition, select the influence range, the location of the incident, the incident time and so on as the judgment index, use the fuzzy comprehensive evaluation method to judge the emergency grade of the event. And according to the level of emergency to formulate the corresponding organizational plan for the traffic emergency management department to quickly deal with traffic emergencies to provide a scientific and effective method. Finally. This paper assumes that bus spontaneous combustion occurs somewhere in Jiazhou Road, Jiangbei District, Chongqing, and carries out emergency traffic organization according to the research. And through the simulation software to verify the effectiveness and feasibility of the implementation of the organizational plan. This paper takes the traffic emergencies of urban trunk roads as the research object and establishes the emergency evacuation model which takes both rescue and guidance into account. In order to improve the ability and decision-making level of traffic management department to deal with traffic emergencies, the judgment method of emergency level is put forward, and the corresponding organization plan is made in order to improve the ability of traffic management department to deal with the emergency of traffic emergencies on urban trunk roads.
