EasyChair Preprint no. 11407

Abstract

National highway Route 228 is a main national highway connecting Hakodate City and Esashi Town in Hokkaido, Japan. At the Kaminokuni Town Odome-intersection, which is located between these two cities, roundabout operations began in October 2019. The percentage of heavy vehicles including trucks and semi-trailer trucks at the intersection is as high as approximately 20%. After the intersection had been improved, an actual driving experiment with a semi-trailer truck was conducted to obtain driving behavior data. The speed of the semi-trailer truck in the roundabout was approximately 15 km/h, and a maximum lateral acceleration of 0.17G was recorded. Both before and after the improvement of the intersection, the proficiency level in roundabout traffic rules, driving performance and safety of heavy vehicle drivers of 10 transportation companies was investigated. As of September in 2019, before the start of the roundabout operation, the proficiency level of heavy vehicle drivers in roundabout traffic rules was low, and the proficiency level in traffic rules that allow the driver to use the truck apron was only 25%. In October 2020, one year after the start of the roundabout operation, the positive effects of shortening travel time and ease of safety confirmation of intersections were demonstrated.
