There's a few cycle routes that go through places where cycles are not allowed, tunnels and bridges, such as the Dartford crossing over the River Thames at Thurrock.
In places like these, there's a cycle shuttle service - where the crossing control people (who escort the dangerous loads etc) will load the cycle onto their vehicle at a rendezvous point, and you ride with them through the tunnel, and they unload you and your bike at another rendezvous point, where you can continue the journey on your bike. There's a similar service through the Channel Tunnel (though that one costs money, and needs booking in advance) Of course, a cycle route planner should know that this is a route available to cyclists. Is it a ferry, available only to cyclists? How should this be tagged? How should the rendezvous points for the service be tagged? For that matter, how should the normal motor vehicle Eurotunnel service through the Channel Tunnel be tagged, Motorail services, or other vehicle carrying land-based services be tagged? (I think this was discussed briefly on the talk-de list back in November 2007) The routing engines should be able to cope with the concept of your chosen mode of transport temporarily being able to transit a link (eg, rail tunnel) that would normally not be available to it, without being carried by another vehicle. It's conceptually the same to a routing engine as a ferry and ferry_terminal, but you might not want it rendered on maps the same way. -- Simon Hewison _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
