Abstract
In recent years, the number of elderly drivers' accidents are rapidly increasing. The increase will continue in the aging society of the future. Therefore it is necessary to reveal elderly drivers' characteristics of braking to prevent their accidents. This paper examines elderly drivers' characteristics of braking, especially drivers' braking time, in comparison of the young drivers based on the data of indoor experiments. We analyzed various factors such as leading vehicle velocity, leading vehicle deceleration, following velocity, following vehicle acceleration, relative velocity, relative acceleration, distance between cars, time headway, TTC (Time-to-Collision) by multiple regression analysis and neural network. The big difference in braking characteristics was not found between elderly drivers and young drivers.
