As for truncated domes, they are a bad idea. Long white canes easily catch in the bumpy surface. When the weather is rainy, snowy or icy, the surfaces tend to become slippery. I remember the first time I encountered one, I was on my way to a job interview. It was on an elevated train platform. I was wearing shoes with high heels. I thought, "One misstep and I could end up in the tracks under a train." Also, when I stop to think about the way pedestrians travel in downtown Chicago. We all move pretty rapidly. I can envision someone tripping and falling. A serious injury could result.

Please consider all this before you make the decision to place these devices in our midst. Most of us don't want them and don't need them.
