DETERMINING THE SAMPLE SIZE OF SUBJECTS ON A DRIVING EXPERIMENT TO EVALUATE PASSENGER ACCEPTANCE OF PAVEMENT ROUGHNESS [PDF]
, 2008 本研究の目的は，路面平たん性に対する利用者許容度の体感評価において，統計的に必要な被験者数を検 定力分析により算定する事である．被験者数は，統計的有意水準，母集団効果量，検出力の関数となるが， 効果量については，個々の研究に委ねられる．そこで本研究では，ドライビングシミュレータによる体感評 価試験から，平たん性評価における効果量を算出した．その結果，中から大の効果量は，車両上下加速度実 効値0.35m/s2 以上の低減が見込める場合であり，この場合20 名以上の被験者数でよい事がわかった．一方 ...
