[Tagging] roundtrip

Thoughts on the subject....

For a route to be a round trip on public transport it would be required that only one ticket purchase would be necessary to take you full circle, and this would include a tourist bus that allows you to get off and back on again along the route until you get back to the original start point. 

A river cruise would fall into this same category even though it will go up one side of the river and back down the other to the original start jetty and requires a single round trip ticket. If there is a disembark point along the route and a new ticket is required to return then this is not a round trip and could use the roundtrip=no tag as a warning for users planning their trip

This means that a bus that has a route that takes it to a destination and then you need to buy a return ticket to get back along the same or similar route to the original start point cannot be a roundtrip.

Falling into this train of thought would it apply to a tourist train that takes you along a dedicated route to a destination, allows you to get off and look around then get on the same train and head back to the original destination, all included in the single ticket purchase. Being careful here because they may have a separate cheaper ticket if you are only going to the destination, in which case would the tourist trip be  a return ticket (or a roundtrip ticket?)

So a roundtrip would not necessarily indicate a circular route but could also be used to indicate that there is a single roundtrip ticket such as a park-and-ride bus or river cruise that returns you to your original destination in one journey.

Thanks for the example.
Looks to me the bus will have to drive through the tunnel for its next round. This route just needs to be completed! Now it's a oneway route. The route_master only contains one relation in one direction.

Similarly, a route that is not closed can be a roundtrip. The start and end points might be several meters apart, even on different roads, yet serve the same destination. There are a few (very few) examples I have found in the Paris area. Here's one. It's not marked roundtrip=yes but probably should be:


I agree that this tag seems to be of very limited usefulness, though I confess to having used it on occasion.

What is the use of the key:roundtrip?  
Explanations just say  
(optional) Use roundtrip=no to indicate that a route goes from A to B. Use roundtrip=yes to indicate that the start and finish of the route are at the same location (circular route).
It seems rather pointless to tag an obvious a-b route with roundtrip=no, or an abvious roundtrip with roundtrip=yes. 
Why would you tag an a-b route as roundtrip=yes, or a closed route as roundtrip=no?

A route that is 'closed' can be a non round trip. 
For example the bus only does one circuit then goes on to another route elsewhere. This can be done to provide services to both that route and to other parts of the community with other routes. 
There may not be enough demand for a continuous circuit to be viable.
