Abstract

<p>When a traffic jam occurs on the main line road, many vehicles, such as compact vehicles or light motor vehicles, etc., which have a small turning radius, try to detour to nearby side roads where they can run smoothly. In this study, authors applied the function of ETC2.0 and measured the velocity change and traffic volume in each section by dividing the road into small sections of about several meters. Then, authors analyzed traffic jam conditions of main line road and the occurrence of detour traffic of vehicles entering residential areal roads to avoid traffic jam, and obtained the changes in the traffic jam conditions and the traffic volume on residential areal roads depending on the time zone.</p>
