I am part of a group working on a trash signage campaign. Our goal is to reduce trash in problem areas while trying to raise public awareness of the watershed that the sign reader is in. We are in the process of applying for a grant and one task we need to do is demonstrate meaurable goals about the effectiveness of the signs. I was wondering if anybody could direct me to evaluations that have been done on the effectiveness of trash signage, so as to get more possibiities about how to measure the effect. Obviously, one way would be to establish a baseline and then do a survey of the amount of trash before and after the sign is impemented. Are you aware of any other methods of evaluation?
