I've noticed that the routing engines avalable on often route pedestrians down the roadway when a sidewalk is mapped as a separate way. I added the sidewalk=separate tag to some roadways in my area, but it does not seem to make a difference. Do any routing engines give any weight to the sidewalk=separate tag? Is there some other way I could help routing engines stick to footways when they are a better option?

It's not a big thing, but It'd be nice if they routed on the sidewalk when it's available.

Edit here's an example.

It might be worth providing a link to a specific example, in case there is something about the mapping that could be improved.

As an aside, I wouldn't use the routing engines on for anything too serious - they're basically just there to say "you can do routing with this data". For example:

seems to think that "how trunk roads are mapped in Germany" applies to the rest of the world, and ignores the "sidewalk" tag on altogether. For completeness

doesn't make the same mistake.

Solving this globally is a hard problem to solve, and not really a fair thing to ask of a simple proof-of-concept.

I know of this dedicated Routago pedestrian routing engine. It was specifically developed for blind people to receive safe walking routes. For that reason it might not always produce the shortest route but it uses sidewalks.
