In the Australian design there’s generally an arrow indicating which direction it goes. It’s embossed to for vision impaired people to be able to feel it too (it also is designed to resonate so if you touch it, you can feel the audio signals so if there are two directions, a vision impaired person knows which direction the sound is saying is safe to cross without needing to see the light signals).
