摘要
隧道内烟雾环境会对驾驶员视觉认知过程造成一定的干扰,而真实隧道烟雾环境下的光源特性测量及驾驶视认实验,既风险高也不具有重复性。研究通过隧道模型的模拟实验方法,对隧道内烟雾环境进行模拟,并测定驾驶员在不同光源照明下对障碍物的视认反应特性。实验得出了隧道烟雾环境下最佳视认性光源色温范围,并进一步通过驾驶模拟实验比较隧道烟雾浓度与车速对驾驶员视认安全的影响,可为隧道通风及照明设计提供参考。
Tunnel smoky environment will cause some disturbance to driver’s vision cognitive processes.It’s difficult to do experiment about light source characteristics and driving vision recognition measurement in real tunnel because of the high risk and unrepeatability.This study was designed to measure driver’s vision recognition under different lighting and smoky environment in simulation tunnel model.Through the experiment,we can find the color temperature range of the light source with the best vision cognition in smoky tunnel environment,and the influence of the smoke density and the driving speed on driving vision safety by driving simulation method.
