Index of quantitative evaluation of degree of barrier-free on side walk is required in order to make progressively barrier-free. In this paper, we suggested an index of quantitative evaluation that can evaluate the physical workload of movement on side walk about manual moving body with wheel. We devised a method to evaluate the difficulty of movement on side walk by angle of basic road. It is possible to evaluate the difficulty of movement on side walk without measuring angle of vertical and cross slope, surface roughness on side walk, and material of the side walk, etc. We examined which index of quantitative evaluation is useful by verification experiment. We measured the difficulty of movement by electric wheelchair's consumed current, and estimated physical workload of manual wheelchair users based on index of moving difficulty. As a result, it was possible to estimate the physical workload of manual wheelchair movement (relative error = 15.1%, r > 0.93, p < 0.01). It appears that the proposed index of difficulty of movement is useful to evaluate degree of barrier-free on side walk.
