災害時要援護者の市街地津波避難の搬送速度に関する実験車椅子、介助車、シルバーカーを用いた3種類の勾配における屋外介助走行速度の比較

摘要

本研究では、坐位保持可能な要援護者を効率よく搬送するための基礎データを得ることを目的として実験的方法により要援護者の体重を調整したうえで、介助走行時のシルバーカー、介助車、車椅子の3機種を用いて、市街地津波避難を想定した急斜面、緩斜面、平面の3種類の斜度別実験コースにおける速度を比較検討した。なお、実際の市街地避難の速度は、周囲の群衆および避難路や周辺構造物の損壊の影響を受ける可能性があるが、それら周囲の影響を可能な限り排除した単独走行時の結果を分析した。%The purpose of this study is to measure the transportation velocity an evacuation supporter carried a vulnerable person to evacuate from Tsunami by using three instruments. We carried out experiments with (A) a rollator, (B) a transport chair and (C) a wheelchair in three forms of the lane, steep slope, gentle slope and flat. The role of evacuation supporter pushed each instrument with loading a vulnerable person onto each one on the supposition that Tsunami had occurred. The order of average velocity was (A) a rollator, (B) a transport chair and (C) a wheelchair. Additionally, the results demonstrated that evacuation supporter's help with transportation tools enable vulnerable people to run away from Tsunami faster than doing by themselves. Based on our findings, a wheelchair is most useful but we also suggest using other two instruments in case helping vulnerable people.
