If you've ever walked on a sidewalk, you've probably encountered the "beg button" at one point or another. That's the button you press in order to get a pedestrian walk signal to light up on the other side of the road. As Alissa Walker writes in a recent Gizmodo article: "Those little buttons on walk signals have been nicknamed "beg buttons"—because walkers are pretty much begging to be able to cross."

This is problematic for a number of reasons, but the biggest is the obvious prioritization of car movement over pedestrian movement. Do car-drivers have to pull up to each intersection, lean out their window and push a button in order to get a green light? No, they just wait and the light appears. The Gizmodo article continues:

It's annoying for walkers: have you ever tried to walk a few blocks, stopping to hit the button at every single intersection? Or hit the button just a few seconds too late and had to wait a whole additional cycle? But it also illustrates the backwardness of our street design: pedestrians, who are supposed to have the right-of-way, are required to press a button at an intersection in order to get a walk signal, which should happen automatically.

We know that walkability creates value in a community. It invites people out onto the streets, interacting with one another, visiting local businesses and participating in the livelihood of a place. So why do our cities, time and again, in so many different ways, continue to limit walkability and make it more and more challenging to walk?
