Driving Behavior Analysis in a Large Earthquake Using a Driving Simulator

Abstract

In the earthquake directly under the Tokyo metropolitan area that is expected to occur in the future, there is a concern about collision accidents and road blockages caused by the driver's steering wheel and brake operation due to the earthquake motion at the time of the disaster. In particular, on highways that run at high speed and high density near the epicenter, it is necessary to examine damage assumptions and countermeasures that take into account the driver's driving behavior during an earthquake. However, the driving behavior at the time of an earthquake is still in a situation where sufficient knowledge has not been obtained due to the difficulty of observation, and further elucidation is required. In this study, we obtained driving behavior data assuming an earthquake during indoor running experiments using DS. As a result, it was suggested that the deceleration behavior differs depending on the timing of the information provision on the earthquake early warning, and that the driver with less frequent driving tends to take a unique deceleration behavior during an earthquake.
