Speed Lines

In Virginia they're painting zig-zag lines on the road. The idea is to visually overwhelm drivers as they approach a busy intersection and bike/pedestrian path, causing them to slow.

VDOT says similar programs have been successful in the United Kingdom and Australia. The transportation agency will study the zig-zagging lines for a year and see if they actually reduce speeds. -WTOP.com

Sounds good to me!
