we have a local mup that has walk signals and stop signs for the mup. I stop for the stop signs and then proceed no matter what the lights say. I'm not walking. What makes this easier in this case is the stop signs, and the fact that there is actually no walk cycle, there are always cars that can go through the crosswalk. In fact, the "walk cycle" is short and coincides with the left turn cycle for the cars that cross the crosswalk. So I'd rather pick my way through when no cars are present.
