Wulf, Gabriele, Hancock, P. A. and Rahimi, Mansour (1989): Some Causes of Automobile-Motorcycle Collisions. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 910-914.

“Motorcycles are overrepresented in fatal motor-vehicle accidents. In the attempt to reduce the frequency of automobile-motorcycle collisions, numerous studies have manipulated motorcycle and motorcyclist characteristics to enhance conspicuity. In this paper, we review of studies that have examined the effectiveness of these measures. Furthermore, we identify factors yet to be considered in the empirical research in this area that may contribute to collisions between cars and motorcycles. These include information-processing failures at the identification and decision stage, as well as relatively stable and volatile factors potentially responsible for different information-processing failures.”

Hancock, P. A., Wulf, Gabriele, Thom, David R. and Fassnacht, Peter (1989): Contrasting Driver Behavior during Turns and Straight Driving. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 918-922.

“In automobile-motorcycle collisions, one particular configuration clearly stands out above all others. This dominant case sees the automobile driver turn left across the right-of-way of the on-coming motorcyclist. Our attempts to understand this particular accident have focused upon the actions of the driver. In the results of the experiment reported here, it is clear that turning involves a higher probability of structural interference to visual information processing and increase in mental load compared to straight driving. These effects are implicated in increased detection failure. The outcome of detection failure is radically different for left versus right-turns. In the former case, a turn is made across the face of on-coming traffic compared to the latter, more benign condition where no traffic conflict is liable to be experienced. The implications of these findings for enhancing motorcycle conspicuity are examined.”
