I'm not aware of extensive studies that have been done. I think often municipalities take on that role. As you mentioned, communities build themselves around tracks, and eventually traffic and congestion develop and other safety issues may develop. Part of it has to be the community itself reaching out to the railway. Obviously, the railway also has to reach out to the community. If we are seeing, as Jean explained before, incidents and we measure them and we know when they happen and how often they happen, we will reach out to communities to do something to help us, whether that means programs, as Jean described earlier, or whether we have to start looking at better ways of protecting citizens and better ways of ensuring that traffic flow is safe and can move.
