This article describes one experiment that studied the influence of Daytime Running Lamps (DRL) on pedestrian detection of turn indicators.
An experimental device including one DRL and one turn indicator was used in order to determine Visual Reaction Times (VRT) of 148 observers in different situations involving turn indicator activation. Such situations were combinations of three main variables: color of DRL, separation between DRL and Turn Indicator, and observation angle.
Significant changes in VRT were found depending on the configurations above, especially the observation angle and the color of DRL. This second result demonstrates that amber DRLs inhibit the detection of Turn Indicators.
One of the main targets of this paper is to recommend that carmakers introduce only white DRLs on new vehicles. We also intend to advise regulatory bodies working on automotive regulation about the consequences of allowing amber DRLs and also about the danger of introducing constrains on the distance between DRL and Turn Indicator without further experimental evidences.
本文描述了一项实验，研究了日间行车灯（DRL）对行人对转弯指示灯的检测的影响。
实验设备包括一个 DRL 和一个转弯指示灯，用于确定 148 名观察者在不同情况下的视觉反应时间（VRT），这些情况涉及转弯指示灯的激活。这些情况是三个主要变量的组合：DRL 的颜色、DRL 和转弯指示灯之间的距离以及观察角度。
根据上述配置，VRT 发生了显著变化，尤其是观察角度和 DRL 的颜色。第二个结果表明，琥珀色 DRL 会抑制对转弯指示灯的检测。
本文的主要目标之一是建议汽车制造商在新车上仅安装白色 DRL。我们还打算建议负责汽车法规的监管机构了解允许琥珀色 DRL 的后果，以及在没有进一步实验证据的情况下，对 DRL 和转弯指示灯之间的距离施加限制的危险。
