Study on Safety Secured with Road Width and Corner Cut Edges in Land Consolidation Projects

Abstract

　The use of large machinery is important for agricultural field improvement projects. However, the suitable road widths and corner-cut edge lengths are under-researched. In this study, we examined the road widths and corner-cut lengths suitable for large machinery by CAD simulation. On a branch farm road, a 35 PS tractor with 3 m harrow and 2 t truck required a road width of 4 m, road width of 4 m, and corner cut edge length of 1.5 m with obstacles. On the main farm road, a 60 PS tractor with 5.5 t trailer and 4 t truck required a road width of 5 m and corner cut edge length of 1.5 m and road width of 7 m with obstacles.
