Short abstract:
Car-to-cyclist crashes frequently occur in traffic accidents and many researchers are now focusing on collision avoidance and injury mitigation of cyclists.
In this presentation, our research topics on car-to-cyclist crashes are introduced. First, drive recorder analysis was performed in order to examine the factors that differentiate car-to-cyclist crashes from near crashes and identify the causes of the crashes. The results showed that car-to-cyclist crashes would not be avoidable when the car approaching the cyclist enters an area where the average deceleration required to stop the car is more than 0.45 G. Second, using data from drive recorders, accident reconstructions were performed and the performance and limitations of AEB systems were investigated. Using a 50 degree field-of-view with a braking delay time of 0.5 s resulted in avoiding six cases out of forty of 90-degree, car-to-cyclist intersection collisions. Finally, the head protection with cyclist helmets in impacts against the A-pillar was investigated from experiments and finite element (FE) analyses. It was shown that the helmet liner has little effect on the HIC.
