Hi all,
I am the lead developer of Aubin which is a public transport journey planner
using OpenTripPlanner as its backend. We have now released an update which
shows the position of the station entrances where you need to use during
your journey on the map.
This feature has helped me a lot in finding errors in underground station
mappings, because if I expect to use an entrance to go underground but a
symbol doesn't appear, it strongly suggests that there is some mess up in
the map which makes me teleport between levels, or alternatively the
platforms aren't mapped properly with the right naptan:AtcoCode populated,
or the entrance themselves not being mapped, or the platforms aren't
correctly connected to the street network. I have already found and fixed
some errors in the map like Oxford Circus.
I am not trying to promote the features of Aubin not directly related to
OpenStreetMap but you should try to use it because it uses OpenStreetMap
data to guide you directly to the best entrance to the correct platform,
giving a realistic time to access / change trains, as long as the map data
is of high quality.
Also, I live in London, if you find some dodgy journey planner results
planning a trip in London but can't fix it yourself, please let me know
where the problem is and I may be able to have a site visit (I did some in
South East London yesterday).
Thanks,
Michael
Further to the above, please also check that the app can correctly show the
platform numbers for metro journeys. They can be shown in the app when all the
following are present:
- a `ref` on the platform
- a `naptan:AtcoCode` on the platform
- the platform is a member of the stop area
If multiple platforms function as a group (for example, terminus platforms),
tag them with the same `naptan:AtcoCode`, in such case we can show in the app
in the format such as "Platform 3-6".
Please help to complete these information in the map.
Thanks,
Michael
