Most traffic accidents come of collisions between two objects in the road transport system. It was assumed that the driver's failure to stop before a collision is caused by a combination of insufficient headway and unforeseen greater stopping distance, and that the human factors which lead to accidents comprise both the driver's tendency to exhibit an unusual delayed reaction or cognition, and a tendency to maintain an insufficient headway. On the basis of this hypothesis, the driver's choice reaction times and the tendency to hasten were measured. Accident-prone drivers showed more irregular reaction times than non-accident-prone drivers, and/or accident-prone drivers showed higher scores on the hastening test than non-accident-prone drivers. It can be concluded that the human factors leading to collisions while driving are the driver's irregularity in reaction times, which can result in a sudden delay in reaction and a stopping distance than usual, and the driver's tendency to hasten, which can result in a shorter headway being maintained. To educate to keep sufficient headway, it was effective to educate them that driving at the higher speed would not give meaningfully shorter traveling time, and derive more fatigue and risky situation than driving at the safe speed.
