机动车交汇时灯具炫目性的讨论

在背景亮度为1 cd/m2的晚上,摩托车及汽车驾驶员无论使用近光灯、转向信号灯或专用昼间行驶灯,在各交汇距离相对上升对比度阈值小于2时,均不会产生炫目,不会影响对向行驶摩托车驾驶员的观察和判断能力;而摩托车和汽车远光灯在任何距离时的相对上升对比度阈值远远大于2时,在摩托车和摩托车交汇时,会产生炫目,造成交通行驶隐患.

A Discussion on Lamp Glaringness when Motor Vehicles Meeting

In the evening with the background light intensity of 1cd/m~2,no matter what lamps motorcycle drivers or automobile drivers use such as dipped head lamp, turn signal light or special diurnal driving light with the meeting distance to the rising contrast threshold value less than 2, glaringness would not produce,thus not influencing the observation and judgement of the driver when the motorcycle running;when the threshold value is much bigger than 2,glaringness will produce which causes a hidden peril to traffic.
