In preparation for the meeting today, I talked to my colleagues who are economists and asked them the same question. They said that the research has not identified a magic distance. In other words, they have been unable to determine whether demand would be lower with a longer distance or higher with a shorter distance. It is a continuum. Later on, we can provide the committee the details on how we arrived at this figure. In general, we found that this distance was optimal for access to rail lines.
