【摘要】：我国高速公路事业的发展，给社会带来显著的经济效益。近几年，极端异常天气时常发生，给高速公路运营安全带来极大隐患。本文通过对低能见度气象对高速公路交通流运行状态的影响和交通事故的分析，研究主动发光诱导设施控制策略和设计理念，确定符合低能见度气象条件下主动发光诱导设施的设置原则和方法。本文依托低能见度气象条件下主动发光诱导设施实验，通过主观评价和客观数据分析两方面，验证主动发光诱导设施设置原则和方法的合理性，确定主动发光诱导设施在有差别的能见度条件和不同工作模式下的实际效果。试验结果显示，设置诱导设施可大大提高低能见度条件下高速公路的通行能力和运行安全。论文以乌鲁木齐东绕城高速公路甘沟立交至米东立交段低能见度常发性路段作为工程案例，结合项目实际情况，提出主动发光诱导设施设置方案。通过本文研究，提出适合在低能见度气象条件下主动发光诱导设施设置原则和方法，对低能见度常发性高速公路的主动发光诱导设施设置起到理论指导和技术支持。
[Abstract]:The development of expressway in our country brings remarkable economic benefits to the society. In recent years, extreme abnormal weather often occurs, which brings great hidden danger to highway operation safety. Based on the analysis of the influence of low visibility weather on the traffic flow and traffic accidents, the control strategy and design idea of the active luminous induction facility are studied. The setting principle and method of active luminescence induction facilities under low visibility meteorological conditions are determined. In this paper, based on the experiment of active luminescence inducement facility under low visibility weather condition, through subjective evaluation and objective data analysis, the rationality of setting principle and method of active luminescence induction facility is verified. The actual effect of the active luminescence induction facility under different visibility conditions and different operating modes is determined. The experimental results show that the setting of induction facilities can greatly improve the traffic capacity and operation safety of the freeway under the condition of low visibility. This paper takes the section of low visibility and regular occurrence between Gangou Interchange and Meidong Interchange of Urumqi East Roundabout Expressway as an engineering case and puts forward an active luminescence inductive facility setting scheme combined with the actual situation of the project. Through the research in this paper, the principle and method of setting up the active luminescence induction facilities suitable for low visibility meteorological conditions are put forward, which can provide theoretical guidance and technical support for the setting up of the active luminescence induction facilities of the low-visibility and normal-occurring highway.
