平原地区高速公路交通运行特征及事故预防措施研究
Research on Traffic Operation Characteristics and Accident Prevention Measures of Expressway in Plain Area

随着社会经济水平的提高和机动车保有量的不断增长，高速公路网交通流量逐年递增。为了降低典型高速公路路段交通压力，减少高速公路交通事故，本文分析平原地区高速公路交通交安安全影响因素，以河南省平原地区典型高速公路安罗高速安罗段和京港澳高速新乡至郑州段为例，通过现场调研和资料调研相结合的方法，分别在高速公路上的基本路段、匝道出入口路段、收费站互通路段和桥梁等特殊路段等路段采集相关数据，分别对路段状况、交通量特征、运行速度特征和事故特征进行分析，掌握平原地区高速公路安全运营状况及存在问题，并提出有针对性的事故预防与安全保障措施。研究成果的应用和推广将会减少平原地区高速公路交通安全隐患，提升高速交通安全水平和高速公路的运营管理服务水平，具有重要的理论意义和实用价值。
With the improvement of the socio-economic level and the continuous increase in the number of motor vehicles, the traffic flow of the highway network is increasing year by year. In order to re-duce the traffic pressure of typical highway sections and reduce highway traffic accidents, this paper analyzes the influencing factors of highway traffic safety in plain areas. Taking Anluo sec-tion of typical Expressway in plain area of Henan Province and Xinxiang Zhengzhou section of Beijing Hong Kong Macao expressway as examples, relevant data are collected in basic section, ramp entrance and exit section, interchange section of toll station, bridge and other special sections of expressway by means of field investigation and data investigation. This paper analyzes the road condition, traffic volume characteristics, operation speed characteristics and accident characteristics, grasps the safe operation status and existing problems of expressway in plain area, and puts forward targeted accident prevention and safety guarantee measures. The application and promotion of the research results will reduce the hidden dangers of highway traffic safety in plain areas, improve the level of highway traffic safety and highway transportation quality, which has important theoretical and practical significance.
