kfd4edu Tuesday, April 21, 2009 Riley, I think it’s an interesting idea and a rather inexpensive way to slow motorists in school zones, etc IF it works. I’d love to see some data on this method. We will have to see what Loudoun’s speed trackers find out. I wonder if they tracked speeds and decrease in speed before putting the lines down so they could compare against a baseline? They should also track speeds again a year out, to make sure the lines are actually effective at reminding folks and not just effective at confusing them initially. I can see people slowing down when the lines first appear because they don’t know what’s going on, but once they get used to it they may return to older and faster habits.
