Abstract

Safety and smoothness in pavement for pedestrians are required. It has been put in various methods other than method for measurement of walking sensation. However, systematic quantitative evaluation methods have not yet been established. In this study, new pavement in our pavements is added and wireless equipment is introduced, denoising and normalizing using % maximal voluntary contraction on surface electromyogram is processed. Effects on the lower legs due to physical properties of pavement are evaluated quantitatively. Between the physical properties and muscular activities are clarified, and systematisms is tried. As a result, it is clarified that the muscular activities of the lower legs vary with a tendency of one graphical form by differing to stiffness and skid resistance of the road surface. Physical properties for measuring muscular activities of the lower legs can be evaluated quantitatively. Thus it is shown possibility that pavement for pedestrians with a viewing point to human can be to introduce an item of evaluation index.

Vernacular Abstract

歩行者系舗装は安全かつ円滑な移動ができるものとされ，歩行感測定法などの研究が行われているが，体系化された定量的な評価法は確立されていない．本研究は筆者らの既往研究に新たな舗装種および無線測定装置を導入し，筋電図のノイズ除去と表面筋電図法の%MVC法で正規化の処理を施した．また，下腿が受ける影響を表面筋電図法により定量的に評価し，その関係性を明らかにし，体系化を試みた．その結果，下腿の筋活動は路面の硬さおよびすべり抵抗係数の違いによって一傾向をもって変化することが明らかになった．下腿の筋活動を測定することで，舗装の物理性状を定量的に評価できることから，人からみた歩行者系舗装の性能指標の一項目として導入できる可能性が示唆された．
