[Routing] Ferry routing

[Jaakko Helleranta.com]

Cloudmade's routing and maps are based on data from December 2011. Any changes to OSM data after that are not -- and can not -- reflected in the routing results.

I haven't tried any ferry routing (but am interested to hear what works). Perhaps you should try the OSRM? .. Or does that not route via route=ferry? .. And if it doesn't I guess the developers (who are/is very active can easily fix that).

Cheers,

Yes, the route(s) in question are tagged with route=ferry and are connected with the road network via one node (on each end) which are tagged with amenity=ferry_route.  Now that I'm looking closely at it though, one of the routes in question is connected via a single segment way which is attributed with (man_made=pier).

way 155099026 (highway=residential) to way 155099140 (route=ferry) to way 155366127 (man_made=pier)

I'll add a highway=residential on way 155366127 and hopefully that will fix that route.

However, there's another regional ferry route which _is_ connected to the road network, but isn't being routed across.

way 5914611 (highway=residential) to way 5918808 (route=ferry) to way 5903243 (route=ferry) to way 5904227 (highway=secondary).  An example of the (incorrect) route is here:
http://maps.cloudmade.com/?lat=47.835283&lng=-122.426147&zoom=9&directions=48.11213057743938,-122.76045799255371,48.15964474913805,-122.67261028289795&travel=car&styleId=1&opened_tab=1
Is the problem that there are two ferry segments?  Should simply combining them fix the routing?

Many thanks for the help.

I've been having problems routing over ferries with routing servies (Cloudmade or Open Mapquest) who use OSM.  Oddly it seems to correctly route over ferries attributed with route=ferry, but not ferries where the end points are attributed with (presumably correct) amenity=ferry_terminal.  Which is correct?  Is there a bug in the routing, or should the ferry routes/terminals be attributed differently?
