摘　　要：基于虚拟现实(VR)技术建立公路隧道内环境智能辅助决策系统,在不同色温的主灯照明下进行驾驶模拟试验,构建注意力增长率和光源色温之间的度量模型,并给出反应时间的分布规律。结果表明:在隧道入口和出口处,驾驶人的注意力增长率较高,行驶约1 200 m时驾驶人注意力达到最低值;不同的光源色温对驾驶人注意力影响差异显著,色温约6 300 K时最利于注意力的集中;低色温下(2 000~4 000 K)驾驶人对事故的反应时间约为0.78 s,而中高色温下(5 000~8 000 K)驾驶人对事故的反应时间约为0.58 s。An intelligent decision-making system for the environment in road tunnel was established based on virtual reality(VR)technology.Driving simulation experiments were carried out at different color temperatures to establish a measurement model between the growth rate of attention and the color temperature of light source,and the distribution of reaction time was given.The results show that at the entrance and exit of the tunnel,drivers’attention growth rate is higher and drivers’attention reaches the lowest level after driving about 1200 m.The color temperature of different light sources has a significant difference in the effect on drivers’attention.The color temperature of 6300 K is the best for the concentration of attention resources.Under low color temperature(2000‒4000 K),the driver’s reaction time to the accident is about 0.78 s,while under medium and high color temperature(5000‒8000 K),the driver’s reaction time to the accident is about 0.58 s.
