In Loudoun County, Virginia, they're trying out new zigzag road markings at intersections with the WOD hiker-biker trail to try to slow drivers down as they approach the intersection.

I happened to ride that section of trail on the day they painted the markings, and did see drivers slowing down more than usual. However I wonder if the effect will be short-lived, and people will ignore them once they're used to them.

Does anyone else have these kinds of markings near where they live, and if so how well do they work?
