Here in Bellevue, WA they have an interesting (not to say obvious) solution to having a sound play when there are pedestrian crossings in both directions. The north-south ones play a sound, while the east-west ones play a different sound. As far as I've observed, that's consistent throughout the city. Some crossings don't have sound, though. I'll check if they have the cone thing.
