[Talk-transit] NaPTAN case study

[Jerry Clough - OSM]

I'd completely forgotten that tram stops were imported, because they were stored as bus stops in NaPTAN: this is a significant data issue with Nottingham data (3% of data).

I think I've failed to make clear that these examples were of defined stop places which appear to me to be far too diffuse to have any coherence either for transport planners or transport users. However, I don't know enough about NaPTAN rules to be sure of this. I also don't know if anyone else has looked at stop places in the data which has been imported.

The tram stops should not have been imported as bus stops, this
appears to be an error in the Nottingham data - they're identifying
them as bus stops for some unknown reason. But, I think we've covered
it in the past.

Stop places will eventually be expanded to include inter-modal groups,
I've not yet worked with the applicable datasets though.
