一种基于车辆检测器位置和停车视距的隧道节能照明设计方案

A Kind of Design Scheme for Energy-saving Illumination of Tunnel Based on Position of Vehicle Detector and Stopping Sight Distance

合理的隧道照明是高速公路行车安全的重要保障,结合工程实例,基于"按需照明"和"车来灯亮、车走灯灭"的照明方式,考虑隧道内部光源衰减对驾驶员的影响,优化隧道内停车视距模型,根据车辆位置实时开启满足相应照明区域长度的灯具,基于隧道内车速度化规律,计算车辆检测器布设间距,实时修正照明区域长度,并给出不同车流状态下的隧道照明调光原则。

Reasonable tunnel illumination is an important guarantee for the traffic safety of expressway. In combination with engineering practice,based on the lighting methods of ＂ illuminate as required＂ and ＂ light on when cars come,light off when cars leave＂,the model of stopping sight distance within the tunnel is optimized by considering the influence of the attenuation of light source inside the tunnel on the driver. According to the real-time starting of vehicle position,the lamps and lanterns with corresponding length of light area are satisfied. Based on the change rule of travel speed within the tunnel,the layout of vehicle detectors is calculated,so as to provide real-time correction for the length of light area,and offer the dimming principle of tunnel illumination under different states of traffic flow.
