为确保行车安全,针对不同交通控制管理类型的山区公路平交口的交通运行特性进行分析,基于车速折减参数分析和次要道路交通流穿越临界间隙的安全视距分析模型,给出了山区公路不同交通控制管理类型平交口的安全视距计算方法。此外结合云南省山区公路平交口长期数据调研分析,给出了不同交通控制管理类型的山区公路平交口最小安全视距建议值,为山区公路平交口视距设计、施工提供有效理论依据,保障山区公路平交口的交通运行安全。
In order to ensure traffic safety, the traffic characteristics of mountain traffic intersections with different traffic control management types are analyzed. Based on the vehicle speed reduction parameter analysis and the safe line-of-sight analysis model of the secondary road traffic flow crossing the critical clearance, Calculation methods of safety line of sight for different traffic control management level crossing. In addition, combined with the long-term data of Ping Jiaokou of mountainous area in Yunnan Province, this paper gives the recommended values of the minimum safe sight of the Ping Jiaokou of mountainous highway with different traffic control management types, and provides an effective theoretical basis for the design and construction Traffic Safety at Highway Crossing.
