Chair: Lorenzo Stucchi (@LorenzoStucchi)
- [DONE] GTFS (General Transit Feed Specification) standard demand
bus stop, do you work with this standard? How manage this
- ANSWER: Yes, we are working with GTFS data. For informal bus
routes we build virtual bus stops on every crossing - Sören
- Are you planning to support GTFS-Flex?, Felix
- Yes, definitely. Actually, we are running Trufi App in Addis
Ababa already with GTFS Flex and want to migrate the other
cities as well.
- [DONE] How do you create bus routes ?
- if I understood well, you create GTFS from OSM routes ?
- Do you create routes manually with JOSM ??
- [DONE] What are “Digital Principles”? (The speaker mentioned that
the app was developed “along Digital Princples, if you know what I
mean”.) – das-g
- you can see https://digitalprinciples.org/
- (thanks!) – das-g
- [DONE] Which countries in Africa are using it?
- (Ghana and Ethiopia)
- [DONE] Anyone in Tanzania?
- Not yet, please contact us! - Christoph
- [DONE] What level of technical expertise do you need?
- ANSWER: The tech team must be able to develop in Dart/Flutter or
able to learn it - Sören (Trufi)
- [DONE] It was mentioned that the app is customized / localized for
local communities. When travelling several Trufi-enabled places
(cities, countries), do I have to download a separate app for each,
or is there one I could use everywhere? – das-g
- [DONE] Will the app(s) be available of F-Droid?
https://f-droid.org/ – das-g
- Yes, please contact me if you want to help us to publish it on
- We made a try but failed and haven’t tried again. - Christoph
- [DONE] Why are there multiple apps (forks of the original) instead
of one (localized) brand?
- How do you deal with the very chaotic and different ways to map
public transport in OSM? If you have your own model: Is it available
in the OSM-wiki or elsewhere?
- We have a guideline on how we do it:
- Sören will talk about this in his talk at 20:00 UTC - Christoph
- How can you collaborate with companies likke WhereIsMyTransport from
South Africa to target the coverage for more cities?
- Our data is Open Data from OSM and WhereIsMyTransport isn’t
- We could collaborate with companies like WhereIsMyTransport,
because our App could be an add-on to their backend - of course,
we would prefer an open source backend. - Christoph
- [DONE] What does the name “trufi” mean / derive from? – das-g
- Taxi de Ruta Fija :)
- From Bolivia - Enock, Meaning??
- [DONE] Are there issues with internet connectivity in some places
that the busses go? - Gregory +1
- Yes - unfortunately, our app requires right now internet for the
search with OpenTripPlanner Server. - Christoph
- How is market penetration of the drivers app?
- Not yet - we look for a funding to finalize it. - Christoph
- Will the app help the drivers to find their way? — Sometimes the
driver in the villages does not know the exact route.
- What do you mean with “find their way”?
- Yes, but most important share GPS coordinates so that users
know, when the next bus comes.
- Can I see the vehicles in realtime? Like uber vehicle?
- In the future :) - Enock
- Yes, with the driver app. - Christoph
- Are the informations only useable on a smartphone or on a normal PC
- Only smartphone right now. - Christoph
- This app is compatible with the relations of transport created in
- Yes! Using osm2gtfs you have a ready GTFS for OTP - Enock
- Exactly - that’s what we build on. OSM2GTFS is a good option
and our own tool, published on Github.
- Do you think managing (mapping and keeping it updated) bus routes in
OSM is sustainable? - wille
- Yes, I think it is sustainable - Wille, could you write me, why
not? - Christoph
- In some places routes change too much. It’s difficult to map
with relations in OSM, it costs time to be reviewing all
changes and assure information is reliable. Maybe it’s a
good solution if you don’t have official data.
- Yes, that’s a challenge. Therefore, we need a lot of
community efforts. Sören will show later how to do the
work with JOSM.
- Users can also say, when routes are wrong or missing and
track their journey. With many of these trackings, we
want to establish a process to get curated routes to OSM
to keep it up2date.
- BTW, we only work in places without official data. -
- In bad shape here in central Taiwan
- Let’s clean it up together :) - Christoph
- in big cities) Don’t bus companies give GTFS files to Google? Well
ask them for an extra copy.
- Yes, cities with digitizes public transport often already have
GTFS. That is of course the easy start for Trufi :)
- By the way, TRUFI can help maintaining the GTFS accurate and
up-to-date, with the user feedback on missing or outdated
routes. - Christoph
- Thanks for the answers to Christoph and Sören. :-)
