摘　　要：在城市道路不同场景根据道路交通需求设置交通闪烁光是实施交通秩序管理、保证道路交通安全的重要手段之一,闪烁光在道路交通场景中的安全性和有效性研究也是当前道路交通管理中的内容之一。本文基于典型夜间道路场景,通过驾驶人动静态条件下对典型的单体式闪烁光和组合式闪烁光进行识别视认研究,得到110米安全视距下红、黄、蓝、白闪烁光满足驾驶人人眼最低可视性要求的发光强度。研究结果表明路面及道路周边环境光对单体式闪烁光的可视性和警示性影响要明显高于组合式闪烁光,其中红色与黄色单体式闪烁光的警示效果要优于白色,而不同颜色的组合式闪烁光的可视性差异很小。Setting traffic flashing light according to road traffic demand in different urban road scenarios is one of the important technical means to implement traffic order management and ensure road traffic safety.The safety and effectiveness of road traffic flashing light in road traffic scenarios is also an important content of recent road traffic management.Based on typical night road scenes,this paper conducts a visual recognition study on typical single flashing light and combined fiashing light under the driver's dynamic and static conditions,and obtains the luminous intensity of red,yellow,blue and white flashing light that meets the minimum visual visibility requirements of the driver's eyes under the safe visual distance of 110 meters.The research results indicates the impact of ambient light on the visibility and warning of single scintillation light is obviously higher than that of combined scintillation light,in which the warning effect of red and yellow single scintillation light is better than that of white,but the visibility difference of different colors of combined scintillation light is slim.The test data in this paper can provide technical support for flashing light Settings in typical scenes of different roads.
