雨雾天气下不同灯光穿透效果对行车安全的试验研究

Experimental Study of Different Lighting Penetration Effects on Driving Safety in Rain and Fog

为分析雨雾天气情况下不同灯光穿透效果对行车安全的影响程度,首先对大样本被试进行问卷调查,获取被试对雨雾天气情况下开启灯光的选择结果。其次,利用雷达和音频、视频监测系统搭建了试验车,在高速公路环境下对10名被试进行了雨雾天气下不同灯光穿透效果的真实试验。数据分析结果表明:驾驶人在问卷调查过程中表现出了较高的安全意识,97.4%的被调查者认为需要开启雾灯或者双闪警示灯,而实际道路测试结果中只有9.8%的人开启雾灯、12.1%的人开启双闪警示灯。雨雾状态下,雾灯、双闪警示灯、尾灯和不开启灯光4种状态下的车辆能见度平均值分别为171.6 m、158.1 m、137.6 m和124.8 m,双闪警示灯的穿透效果要比雾灯差。

In order to study the real traffic environment, where the influence of diferent lighting penetrationeffects on the safety of vehicle during the rain and f g ,large sample subjects were surveynaires which in order to get the choose of flashing warning lamp and f g signal light. And the test vehicle with theDelphi ESR radar and camera of real-time field collection was built,which recording the vehicle’s running in the rain and fog by 10 subjects. The analysis shows that drivers in the questionnaire survey showed a high degree of se-curity awareness,and 97. 4% of the respondents believe that they would open the fog lights or double flash warninglights. However,only 9. 8% of tlie actual road-test results turned on the fog lights and 12. 1 % of double-flash warning lights. Under the condition of rain and fog, the average visibilkinds of states were 171. 6 m,158. 1 m,137. 6 mand 124. 8 m respectively under the condition offog lamp,doub- le flashing warning lamp,taillight and no light. Therefore,f g lamps’ penetration effect warning lights.
