Driving Bearing Evaluation System to Achieve Eco First Haulage Work

This paper presents the drive bearing evaluation system to quantitatively describe and evaluate driving peculiarities and styles regarding dump truck drivers in a haulage work. The drive bearing represents appearance and motion in driving. It would provide site-manager and resident engineers with quantitatively suitable indices to guide or instruct drivers under their control with the objective of increasing haulage efficiency and achieving the ECO first haulage work. Firstly, this paper presents existing problems latent in a fleet management for a haulage work and the purpose of this study. Secondly, the ECO first haulage work is explained. Thirdly, described is the configuration of the drive bearing evaluation system that has a site process database in which actual driving data are preserved, and that automatically edits the data to produce daily and monthly reports and to issue driving evaluation cards for each driver. Fourthly, reported is the application of this system to haulage work of no-slump concrete for multilayer sediment control dam by unmanned construction in the Unzen restoration project. Finally, remarks are presented.
