In this study, an experimental study based on the target visibility criteria is carried out for dark and foggy environments, where only vehicle headlights are active. More specifically, the performances of the headlights containing halogen, xenon, and LED light sources in dark and foggy weather conditions are examined and the performance of each headlight is evaluated separately. According to the general result of the visibility experiments, the participants perceived the target object in a shorter time when halogen headlights are used. It is also observed that the average target perceived times of the participant under foggy conditions are at different levels depending on the type of headlights with different correlated color temperature (CCT) and color rendering (CRI) indexes. According to the experimental results performed under foggy conditions, the target detection times of the participants are the shortest at the halogen headlight, the second at the xenon headlight, and the third under the LED lights. It has also been observed that this sequencing is gender-independent. However, the ratio of the detection time of female participants to that of male participants varies between 1.72 and 3.65 times. In other words, female participants perceive the targets in a much longer period than male participants.
本研究针对黑暗与雾天环境（仅开启车辆头灯），基于目标可视性标准进行了实验研究。具体而言，检验了包含卤素灯、氙气灯和 LED 光源的头灯在黑暗与雾天条件下的性能，并分别评估了每一种头灯的性能。根据可视性实验的总体结果，当使用卤素头灯时，参与者感知目标物体的时间更短。还观察到，参与者在雾天条件下的平均目标感知时间因具有不同相关色温 (CCT) 和显色指数 (CRI) 指标的不同类型头灯而异。根据雾天条件下进行的实验结果，参与者在卤素头灯下的目标检测时间最短，氙气头灯次之，LED 灯光下第三。还观察到，这种排序与性别无关。然而，女性参与者的检测时间与男性参与者的检测时间之比在 1.72 到 3.65 倍之间变化。换句话说，女性参与者感知目标的时间要长得多。
