本研究は、高齢者の健康の維持・増進と身体機能の低下を予防するためには積極的な外出行動が不可欠と考え、歩行衝撃が小さく、また、熱線の照り返しも少ない木材チップを、歩行者用街路の舗装材料として用いて、歩行環境の快適化をはかることで、季節を問わず高齢者の積極的な外出行動を支援する歩行環境の構築を目的として行った。19年度は、木質チップ舗装の経年劣化の検討を行うために、18年度と同規模の木質チップ舗装路をあらたに設置した。反発係数での評価では有為な差が認められず引き続き経年劣化の評価について研究を継続していく。既存舗装材料との歩行性能の比較評価のためには反発係数による評価は有効であるが、歩行感覚との対応に関しては必ずしも有意な相関関係がなく、そこで歩行感覚と相関の高い歩行衝撃の影響を評価するために、加速度計を踵に設置して衝撃加速度の周波数特性による評価手法の検討を行った。その結果、衝撃加速度の高周波成分と低周波成分の比を衝撃係数として、その数値と歩行感覚とには高い相関のあることがわかった。周波数の閾値の検討に時間を要したため、計画した高齢者による評価実験は実施できず、今後の課題とする。歩行路面の温熱環境の評価のために試験歩行路の表面温度の計測を引き続き行った。夏期の表面温度はコンクリート舗装、アスファルト舗装より有意に低い結果が得られているが、周辺建物の影響など日射受熱量の検討が不十分となっている。そのため、今年度設置の舗装路は十分な日照が得られる地点に設置しており、引き続き、表面温度の計測を行って有効性の検証を行う。以上、木質チップ舗装は、既存のコンクリート舗装やアスファルト舗装より高齢者の歩行衝撃や温熱環境を緩和し、高齢者の外出行動を促進する歩行環境条件の構築に十分寄与できることがわかった。

In this study, people with high levels of health should maintain a low level of physical fitness in order to prevent the active activities of going out. Do not owe the examination, train, pay, save, pay, visit, purchase, shop, train, train, train Those who are highly favored in the middle of the season will actively go out and support those who are in charge of environmental training for the purpose of doing so. In the year of 19, the annual deterioration of the equipment and equipment of the wood was completed, and in the year of 18, the equipment was installed in the same size as that of the road. There are many reasons for the increase in the number of years in which the annual deterioration has been studied. The performance of the existing materials is much higher than that of the existing materials, and the performance of the existing materials is much higher than that of the existing materials. The acceleration meter is followed by setting the acceleration cycle number property, the acceleration cycle characteristic, the maneuver, the operation, and so on. The results show that the acceleration, high-cycle components, low-cycle components, high-frequency components, high-cycle components, low-cycle components, low-cycle components, high-cycle components, high-cycle components, low-cycle components, low-cycle components, high-frequency components, high-frequency components, low-cycle components, low-cycle components, high-frequency components, low-cycle components, high-frequency components, low-cycle components, high-frequency components, low-cycle components, high-cycle components, low-cycle components, high-frequency components, low-cycle components, low-cycle components, high-cycle components, low-cycle components, low-cycle components, high-cycle components, low-cycle The number of weeks must be monitored during the week, and those who plan to do so will continue to do so in the future. The calculation of the surface temperature of the road surface will lead to the operation of the road. In the summer, the surface temperature is very high, and the equipment is not very good in the summer. as a result, the results show that the buildings are affected by the amount of solar radiation. This year, the installation of equipment and equipment is very sunny this year. You can set up the equipment, guide the equipment, and measure the surface temperature. There are some characteristics of the equipment. The above, the existing equipment equipment, the existing equipment, the environment, the environment.
