Abstract
This Paper aims at developing evaluation method of road roughness profile for sidewalks used by bicycles, wheelchairs, and pedestrians, by employing analysis of relationship between IRI index measuredby DAM (potable road profiler) and rating index by cyclists and wheelchair users. The author proposed IRI simulation method for bicycles and wheelchairs. The bicycle IRI index appeared good relationship with rating index. The wheelchair (front wheel) IRI index showed good relationship with rating index of some of sample pavements, except with natural stone pavement, color asphalt pavement, and some type of ILB pavement.
