Out of curiousity, why would you want crosswalk signals? Legally speaking, when no crosswalk signals are present, you can walk when the light is green in your direction. Crosswalk signals decrease your lawful window for crossing the street, since the white "walk" signal always lasts less time than the green "motor" signal. They restrict walking mobility and legal protection for walking, and the gain is what?

The gain is that you can push a button to get a red light to stop traffic on the road you are attempting to cross. I walk this area sometimes and it can be pretty busy and the traffic lights do not change often enough in peak times.
