Innovative motorcycle headlight design for improving motorcycle visibility

Innovatives Motorrad-Scheinwerferdesign für bessere Erkennbarkeit

The most frequent cause of Powered Two Wheeled vehicle (PTW) accidents involves another vehicle that violates the PTW’s right of way at an intersection. Two main causes underlay these accidents: on the one hand a detection (or late detection error, the famous “sorry mate I didn’t see you”), and on the second hand a misperception of the PTW’s speed and time to arrival. Several works have been undertaken over years to determine a better visual signature for the PTWs, and to improve the speed perception of PTWs using additional lighting systems. In a previous research work, conducted using virtual reality, the authors have shown the interest of a vertical lighting configuration to improve the drivers’ perception of motorcycles’ motion. In this paper the authors present the results obtained thanks to a real-world experiment, on track, at dusk and night-time. The participants were in their own car in a left-turn situation while a PTW or a car approaches. The oncoming car used its “standard” front lights. The oncoming PTW used either its “standard” front light system, or a specific “vertical” configuration (“standard” front light plus additional lighting systems on the rider’s helmet and on the PTW fork) aiming at a visual increasing of the vertical size of the PTW. The findings indicated that the “vertical” configuration significantly increased the gap accepted by car drivers towards PTW. The authors discuss the experiment and the results. (A)
