I am speaking for a small developing team that currently develops a small routing service for the BUGA2019 in Germany Heilbronn.
The BUGA2019 is basically a big garden and all streets are tagged with access=private, since you can only access this park if you pay money.
My question is, if I have two points, how can I route through this park (using the streets, that are private).
I couldn’t find any documentation in the open layers API (https://openlayers.org/en/latest/apidoc/) about routing at all.
Every routing service I found (for example openrouteservice.org) does not use access=private streets and does also not have any settings to use private streets.
