【摘要】：随着我国高速公路的大量建设与飞速发展，高速公路交通安全问题日益严重。因地形条件限制，我国山岭重丘区高速公路长大纵坡路段及平纵线形组合路段较多、桥隧比例较大，加上车辆超速等原因容易形成事故易发点段，导致极大的生命和财产损失。因此对事故易发点段进行综合治理改善技术与措施研究十分必要。本文在分析高速公路交通事故易发点段道路、交通及事故特性的基础上，从交通工程角度出发，对高速公路事故易发点段交通安全设施和交通组织优化与管理措施进行了深入研究。首先对高速公路事故易发点段道路特性、交通特性、事故特性及诱发因素进行了分析总结，为实施改善对策提供了思路；其次，在总结分析高速公路交通安全设施类型及功能特点的基础上，对事故易发点段从“视线诱导”、“危险预告”、“强制减速”和“安全防护”四个层次对事故易发点段提出安全设施设置优化方案，并针对长大下坡、隧道、平纵线形组合、互通立交等常见的事故易发点段提出了具体的安全设施改善对策；再次，基于交通组织优化思想与原则，结合事故易发点段货车交通流运行特点，从客货分流交通组织、车速组织方面对高速公路事故易发点段交通组织方式提出了相应的安全改善措施；最后，，从加大对人的安全教育力度、提高车辆安全性能、加强车辆超载超限治理、提高道路安全管理水平、提高事故预测准确度以及完善高速公路交通事故紧急救援体系等长效机制方面提出了改进建议及意见，系统全面的对事故易发点段提出安全改善。
[Abstract]:With the rapid development and construction of expressway in China, the traffic safety problem of expressway is becoming more and more serious. Due to the limitation of terrain conditions, there are more long and vertical slope sections and combination sections of horizontal and vertical lines in mountain and heavy hill areas of China, and the proportion of bridge and tunnel is large, and the overspeed of vehicles is easy to form the accident prone point section, which results in great loss of life and property. Therefore, it is necessary to study the comprehensive treatment and improvement measures. Based on the analysis of the road, traffic and accident characteristics of highway traffic accident prone point, this paper starts from the point of view of traffic engineering. The traffic safety facilities and traffic organization optimization and management measures in the accident prone section of expressway are studied in this paper. Firstly, the road characteristics, traffic characteristics, accident characteristics and induced factors of highway accident prone section are analyzed and summarized in order to provide the train of thought for the implementation of improvement measures. On the basis of summing up and analyzing the types and functions of expressway traffic safety facilities, the accident prone points are induced from "line of sight" and "danger forecast". The four levels of "forced deceleration" and "safety protection" put forward an optimized scheme for setting up safety facilities in the accident prone point section, and for the combination of long and downhill slopes, tunnels and horizontal and longitudinal lines, The specific measures to improve the safety facilities are put forward for the common accident prone points such as interchanges. Thirdly, based on the thoughts and principles of traffic organization optimization, combined with the operation characteristics of the traffic flow of freight cars in the accident prone points, the traffic organization is divided from passengers and goods. In the aspect of speed organization, the corresponding safety improvement measures are put forward to the traffic organization mode of highway accident prone point. Finally, from increasing human safety education, improving vehicle safety performance, strengthening overloading and overloading control, In order to improve the management level of road safety, improve the accuracy of accident prediction and improve the emergency rescue system of expressway traffic accident, the paper puts forward some suggestions and suggestions for improving the safety of the accident prone point.
