基于警示效果的隧道多功能车道控制器光学研究

Optical Research of Tunnel Multi-Function Lane Controller Based on Warning Effect

针对隧道内特殊的背景环境,结合隧道内司机行车视距以及眩光理论分析和建模研究,从确保安全行车和交通警示的原则上分析和研究多功能车道控制器发光强度和安装距离范围,以及红蓝爆闪灯的发光强度范围。研究结果表明,多功能车道控制器在隧道内的设置间隔在250 m~300 m范围内时,车道控制器既能在正常通行时指挥交通,又能够对驾驶员起到警示作用。红蓝爆闪灯的闪光频率在13次/秒之内时,既起到警示作用,又不会对驾驶员造成连续致眩。工程应用结果表明,采用文章所确定参数的情况下,多功能车道控制器可有效降低公路隧道的交通事故率。

Aiming at the special background environment in the tunnel,combined with the driver’s driving line of sight in the tunnel and the theoretical analysis and modeling research of glare,from the principle of ensuring safe driving and traffic warning,this paper analyzes and studies the luminous intensity and installation distance range of the multi-function lane controller,as well as the luminous intensity range of the red and blue strobe lights.The research results show that when the multi-function lane controller is installed in the tunnel within the range of 250 m to 300 m,the lane controller can not only direct the traffic during normal traffic,but also play a warning role to the driver.When the flashing frequency of the red and blue strobe lights is within 13 times/second,it not only plays a warning role,but also does not cause continuous dizziness to the driver.The engineering application results show that the multi-function lane controller can effectively reduce the traffic accident rate of highway tunnels under the condition of using the parameters determined in this paper.
