Study of the senior driver's driving conscious against the specification traffic situation and driving behaviors

Japan is one of the leading country of the aging society. For traffic as well, the number of the traffic accidents caused by senior driver is increasing year by year. So we have to make countermeasure for it ahead of the other countries. Currently, Japanese government moved into actions for example to have the campaign for returning of the senior drivers' licenses, or oblige senior driver who doesn't want to return his/her license to take a driving lessons at the driving school each 3 years. But to resolve this problem, society have to take a radically -new way to support senior drivers they can drive much more safely. It would be help for the senior people to keep healthy life. We had to 2 activity. One was a questioner research to understand what type of the traffic situations have the possibility of the traffic accident caused by senior drivers. The result was, it likely to be better to prioritize supporting for the decreasing visual cognitive ability and judgment for the countermeasures. Secondly, we analyzed senior drivers driving test results using driving simulator to see whether there is any variability of the performance among in senior drivers, and also to see their driving ability tendency.
