Abstract
By Shoshi MIZOKAMI·ERyuji KAKIMOTO·EAkanori AKAHOKO·EAtsuhiro MATSUKI·EItsuki SHIRAKAWA This paper shows the effectiveness of Workshop process on the policy-making, monitoring and evaluation when we carry out a Park and Ride social experimentation. Also, by using the covariance structure analyses, we can find that the preference structure of participants for the P&Rsystem changes after they attend the Workshop.
