The new classification of traffic accident using the quality and the quantity data and the direction for the safety measure

Abstract

The road traffic accidents are always a chronic social issue in terms of economically big loss. Meanwhile, the traffic accidents on Hanshin Expressway have been reduced on account of the various safety measures on the traffic accident-prone spots and the occasional supports to drivers. But it shows that there's a limit in the existing traffic safety actions as a lot of traffic accidents still occur. In this sense, new safety measures with a different point of view are required in order to decrease the number of traffic accidents. This study aims for contributing to reduce traffic accidents further. We suggest the new classification of traffic accidents through the traffic accident factor analysis using the quantitative and the qualitative accident data from the traffic accident database consisting of traffic accident data, traffic data, road structure data, weather data and safety measures data. The influence of traffic accident clusters on society is quantified and the appropriate safety measures for each cluster are proposed.
