Design and evaluation of situation-adaptive pedestrian-vehicle collision avoidance system

The authors investigated effectiveness of a pedestrian-vehicle collision avoidance system that was strictly the compatible with the human-centered automation. The system is designed to perform no avoidance maneuver when the driver does not show his/her intention to avoid a collision. This paper proposes a collision avoidance system that may intervene into control autonomously when the driver fails to show the intent in a highly emergency situation. The results of an experiment with a medium fidelity driving simulator show that the proposed system is effective to reduce the number of crashes that the original one can not prevent. Moreover, analyses on subjective ratings on improvement of collision avoidance capability and appropriateness of the system´s maneuver show that the drivers have accepted the system.
