Crosswalk hacking

Some pedestrian hackers called Cross Anytime have brute-forced and gained some insight on how the crosswalk systems work. Used mainly by politicians and city officials, these commands are given to the crosswalk signals from the “infinite Don’t Walk” to the “Instant Walk”. Apparently there are two different types of systems but both have this next hack in it.

The most popular hack, which works on most models, is the “Instant Walk.” Three short clicks, followed by two long, one short, two long, and three short; turn any crosswalk signal from “don’t walk” to “walk” with a matching change in the traffic signals.

I’m curious as to if this actually works.
