摘要
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。
To ensure traffic safety,in terms of traffic operating characteristics at mountain highway intersection with different types of traffic control and management are analyzed,based on analysis of speed reduction parameter and safe sight distance for minor road traffic crossing critical gap to analyze mode,and the method of calculating safe sight distance at mountain highway intersection with different types of traffic control and management is proposed.Furthermore combining the long-time data collection and investigation at intersections of Yunnan province highways,the recommended values of minimum safe sight distance are put forward to provide reference for sight distance design and construction and ensure traffic safety at intersections.
