Development of autonomous dump trucks system (HIVACS) in heavy construction sites

This paper describes an autonomous dump trucks system called Hazama Intelligent Vehicle Automatic Control System (HIVACS) being developed to overcome worker shortage problems and to prevent accidents in heavy construction sites (i.e., dam construction, road construction, etc.). If this system is applied to the aggregate carriage on a RCD (Roller Compacted Dam) construction site, this system operates five dump trucks without drivers. It is anticipated that this system will enable 17% labor-saving. The algorithm of unmanned operation control is based the "Yamabico" robot that is currently under study at University of Tsukuba. A test vehicle for autonomous dump trucks is developed in this study.
