幹線道路の渋滞時に迂回路とされる生活道路の急ブレーキ発生状況の分析

（ETC2.0データを用いた急ブレーキ発生状況分析による生活道路の交通環境の推測）

When main line roads are traffic jam, many vehicles move into residential areal roads to avoid traffic jam. Furthermore, it is expected that safety will decrease due to the large number of vehicles passing on narrow residential areal roads. As a method to evaluate this, this study focused on the relationship between the occurrence of sudden braking and the vehicle traffic volume. Similar to previous studies, the road was divided into small sections of several meters each, and the relationship between sudden braking frequency and time zone, road section were analyzed. This analysis confirmed that there are cases in which sudden braking occurs frequently and cases in which sudden braking occurs less frequently during time zone when vehicle traffic volume on residential areal roads increases.
