Third Traffic Science Section

The Third Traffic Science Section conducts research on vehicle dynamics, driving characteristics, vehicle safety, accident analysis, and accident investigations from the standpoint of automotive engineering.

Research on In-vehicle Data Recorder

Actual data of vehicle accelerations

Some devices are installed in a motor vehicle to record vehicle and occupant information for a brief period before, during, and after a crash.
To use it for an accident investigation, the method of reconstruction of vehicle motion from EDR data is researched. Also, the reliability and accuracy of EDR data are examined.


Reconstruction of Accidents Including Bicycle or Wheelchair

Crash test

Recently, users of bicycles and wheelchairs have been increasing. To develop reconstruction method of accidents between vehicles and bicycles or wheelchairs, crash tests are examined.
