But until then, other solutions have to be found and could quite easily be implemented, by considering innovative headlight configurations for motorcycles. In two simulator studies, we tested various motorcycle headlight configurations, intended for remedying simultaneously the two perceptual errors made by other vehicle drivers. The impact of different headlight configurations (using colour coding and additional lights) was studied in the presence of visual distractors (car front lights: only LEDs, only dipped beams, LEDs and dipped beams) and in different illumination conditions (nighttime, dusk and daytime conditions). The results of the first study on motorcycle motion perception indicated that headlight configurations that accentuate the vertical dimension of the motorcycle (additional lights on the fork and on the rider's helmet) led automobilists to adopt larger safety margins towards motorcycles. The advantage provided by the innovative headlight configuration showed up especially at low illumination conditions (night and dusk) where the motorcycle outline was not visible or difficult to perceive. On the contrary, a triangular design (with two additional lights on the handlebars) showed no significant improvement.The findings of the second study on motorcycle detection showed that additional yellow lights (on the motorcyclist's helmet and the motorcycle fork) significantly improved motorcycle conspicuity and produced the best motorcycle detection performance, even in the presence of a great number of competing car headlights (when LEDs and dipped beams were lit at the same time). When combining the results of our studies, we suggest a motorcycle headlight configuration that consists in one white central headlamp, an additional yellow light on the helmet and two additional yellow lights on the fork. This ergonomic solution has the potential of successfully counteracting the two kinds of perceptual errors made by other vehicles drivers.]]> Fri, 17 Mar 2017 10:40:16 GMT https://trid.trb.org/View/1460365 Innovative motorcycle headlight design as a means of improving motorcycle perceptibility for car drivers https://trid.trb.org/View/1395431 10 years).
