I'd say your best bet would be straight walkways running east and west, north and south. Many blind people orient themselves based on heading.

Curving walkways are the worst thing

Perfect circles aren't too bad.

I'm not a fan of curving walkways. I get what you're trying to achieve, they are a good way to maximise the use of space, especially in a garden type setting and the tactile features could make it work if the walkway is for meandering purposes. However, if it's a functional walkway where someone might want to get from A to B with minimum delay, it would be unnecessarily frustrating for many visually impaired folk.
Good luck with the project and thank you for seeking imput.

Mobility instructor here. Curvy walkways are the worst! So hard for ppl to keep their orientation. Looks pretty, but it's not really functional.

Maybe you could include those padded (how are they called in English?) Things on the way. The main problem for me and many other blind people is that you don't have any clues how far you went and which direction you are facing.

I agree with the majority straight walkways. I already feel like I pay minimal attention. I struggle with curvy walkways that branch and one keeps going straight and one turns left or right worse is both. I get lost easily.

It also depends on level of awareness. I consider myself a fair traveler of my city and county but open spaces and campuses or areas with those always gets me. When I am more aware which is not all the time I do okay.

I use the edge of the sidewalk, or curb as a guide when my cane finds it. And there lies a problem. Where I live they seem to be fond of curvy curbs at walkways. I’m also partially deaf, so there has been several instances where I have ended up on the street. To be precise, i ended up in the middle of the intersection. Those that are VI and in walkers and/ or wheelchairs using a guide dog will also have issues with curvy walkways. Can you imagine a wheel falling off the edge of sidewalk when it goes “in”? Or a leg of a walker. Just my 2 cents.

Hello there, I personally think the question maybe to general, and to give an answer to it reguardless of the generality I think it is person by person dependent. What may work for me or you or be bad for either may not work or may be bad for the next person.
