山区高速公路急弯陡坡路段交通安全影响分析

Influence Analysis for Traffic Safety in Sharp Bend Steep Slope Section of Mountainous Expressway

山区高速公路急弯陡坡路段交通事故多发,安全生产形势严峻。从平面线形、纵断面线形和平纵线形组合三方面进行分析论证,提出了急弯陡坡路段的界定标准,分析了急弯陡坡的线形条件下驾驶员心理、车辆行驶状态、交通事故呈现出的独有特性,可为山区高速公路的线形设计和安全保障技术研究提供依据。

Traffic accidents occur frequently in the sharp bend steep slope section of mountainous expressway, and the situation of safety production is grim. This paper analyzed and demonstrated from three aspects of horizontal alignment, vertical section alignment, horizontal and vertical alignment combination, the definition standard of sharp bend steep slope section was proposed. The special properties of drivers psychology,vehicle driving condition, and traffic accidents were analyzed. This paper provides evidences for alignment design of mountainous expressway and the research on safety assurance technologies.
