Wow! Back in March 2006, I blogged an idea installing a compass rose at subway exits to help emerging travelers find their way. I posted a stencil design to help inspire action. Three weeks later, graffitti roses appeared in lower manhattan. And now a year-and-a-half later, the New York City Department of Transportation announces a plan to implement it.
The DoT will test the designs in midtown, around the heavily touristed Grand Central area. The context specific labels are a nice innovation, not just pointing north, but naming the nearest street in each direction.
