fancy ferry routing over the med sea with bicycle profile #6782

Closed hannesaddec closed 8 months ago

Issue

Make a bicycle route from Spain to Italy goes fancy via ferries over the mediterrean sea see https://map.project-osrm.org/?z=7&center=42.386951%2C6.042480&loc=40.446947%2C-0.175781&loc=42.098222%2C12.260742&hl=en&alt=0&srv=1

Steps to reproduce

go to https://map.project-osrm.org and choose a spanish and Italian location - see link above. For sure someone can enable exclusion of ferries in the lua file https://github.com/Project-OSRM/osrm-backend/blob/31e31a63d062fb804f5f4695ed3036ca7a269ead/profiles/bicycle.lua#L208 but I doubt that is really the intention..

The reason is that a ferry connection is faster than a bicycle land connection

Looking at the example route you share, this sounds like a fair assumption. In which case this behavior is more of a feature than a bug.

If the plan is to avoid ferry routes altogether in output, this can indeed be done using exclusions, or even better yet by disabling ferry routes at the extract step on your custom instance.

we have a "feature" ! - the workaround would be to add addional land based intermediate stops....
