A study of accident analysis that occur on residential areal roads parallel to the main road

( Traffic route analysis using ETC2.0 data and characteristics of loopholes accidents)

Abstract

In a previous study, the authors have clarified that the traffic volume of parallel residential areal roads increases during the time when the length of traffic jams becomes long on the main road during the morning and evening commuting hours. In this study, we investigated the section where traffic jams occur during the morning and evening commuting hours of National Highway No. 2 in Fukuyama City, Hiroshima Prefecture, and the residential areal roads parallel to this section. Then, the authors verified that the residential areal road is a loophole of National Highway No. 2 by performing a traffic route analysis using ETC2.0 data. In addition, by analyzing the traffic accidents that occur on this residential areal road, we clarified the dangers hidden in this road used as a loophole.
