【摘要】：近年来,伴随着国家综合国力的全面提升,我国高速公路建设迈上新的台阶。受西部大开发发展战略的影响,高速公路建设正快速地向西部山区拓展,目前山区高速公路总里程已超过全国高速公路路网总里程的四分之一,这为西部地区带来快速、便捷交通运输的同时,也带来了事故多、施救难、易堵塞等系列新的问题。尽管国内外已有多名专家学者着手研究山区高速公路关键结构物、高速公路交通事故等应急预警技术,但未对山区高速公路路网整体应急预警系统体系进行研究。为此,本文将在国内外山区高速公路部分关键结构物和交通事故预警技术的基础之上,立足山区高速公路整体通行环境,对建立山区高速公路相关的应急联动模式和预警机制进行研究。根据山区高速公路安全管理的重点与难点,在应对各类应急突发情况时,突出对山区高速公路交通流控制策略进行研究,以保障山区高速公路交通流控制的科学、合理、安全、有效。本文突出对应急预警、应急响应、应急调度、信息发布等综合体系研究,立足山区高速公路公路实际情况,分别提出“一对一”和“多对一”应急和预警联动体系的构想与理论。着重对山区高速公路应急预警响应启动后,按入口匝道控制、主线交通流控制、远端分流控制和优先通行权控制分别对交通流控制策略进行研究。同时,因山区高速公路存在桥隧相连、坡陡弯急、持续长大纵坡、高边坡等特殊的交通环境,本文还重点对弯道、长大纵坡(长下坡)、隧道等山区高速公路的关键结构物交通流控制的具体措施,特别是交通流控制中关键管制(控制)节点的选择,及其交通流控制方法进行深入研究,确保实现山区高速公路交通流控制方法得当,能科学、及时、安全按需求管控交通流。还根据山区高速公路交通流控制重点与难点,以山区高速公路施工的交通流控制为例,分别对控制左侧超车道、控制行车道、控制右侧应急车道、单幅双通和间断放行等正线通道控制交通流的方法进行研究。最后,还将本文研究成果运用在山区高速公路交通流控制的实践中,选择具有典型山区高速公路特点的渝涪高速公路黄草山隧道至古佛收费站段,在对其建立相应数学模型的基础上,按“一对一”和“多对一”应急和预警联动体系的理论构想,分段建立应急和预警联动体系。
[Abstract]:In recent years, with the overall improvement of the national comprehensive national strength, the highway construction in China has reached a new level. Under the influence of the development strategy of the western development, the expressway construction is rapidly expanding to the western mountainous areas. At present, the total mileage of the mountain expressway has exceeded 1/4 of the total mileage of the national expressway network. This brings about rapid and convenient transportation in the western region, and at the same time, it also brings many accidents and difficulties in rescuing. Although a number of experts and scholars at home and abroad have begun to study key structures of highways in mountainous areas, emergency warning techniques such as highway traffic accidents, But there is no research on the whole emergency early warning system system of mountain expressway network. Therefore, this paper will be based on some key structures and traffic accident warning technology of mountainous expressway at home and abroad. Based on the overall environment of mountain expressway, this paper studies the establishment of emergency linkage mode and early warning mechanism related to mountain expressway. According to the key points and difficulties of safety management of mountain expressway, when dealing with all kinds of emergency emergencies, In order to guarantee the scientific, reasonable, safe and effective traffic flow control of mountain expressway, this paper focuses on the emergency warning, emergency response, emergency dispatch, and so on. Based on the actual situation of highway in mountainous area, the paper puts forward the conception and theory of "one-to-one" and "many-to-one" emergency and early warning linkage system based on the research of information release and so on. The traffic flow control strategies are studied according to the on-ramp control, the main line traffic flow control, the remote diversion control and the priority traffic weight control. High slope and other special traffic environment, this paper also focuses on the bend, long longitudinal slope (long downslope, tunnel and other mountain highway key structure traffic flow control measures, In particular, the selection of key control nodes in traffic flow control and the methods of traffic flow control are deeply studied to ensure that the traffic flow control method of mountain expressway is appropriate, scientific and timely. According to the key points and difficulties of traffic flow control of mountain expressway, taking the traffic flow control of mountain highway construction as an example, the left overtaking road, the traffic lane and the right emergency lane are respectively controlled. The methods of controlling traffic flow in single double pass and discontinuous release channels are studied. Finally, the research results are applied in the practice of traffic flow control of mountain expressway. The section from Huangcaoshan Tunnel of Yufu Expressway to the ancient Buddha toll station, which has the characteristics of the typical mountain expressway, is selected. On the basis of establishing the corresponding mathematical model, the theoretical conception of "one to one" and "many-to-one" emergency and early warning linkage system is proposed. Establish emergency response and early warning linkage system.
