Great work :) Nice to see alternatives poping up. There used to be navitia https://github.com/hove-io/navitia/ but its company is slowing closing thing, so I would not bet on it for the future.
I’m a co-maintainer of gtfs-structures, if you have any feedback using that crate I’ll be glad to hear from you (specially since you consume a lot of different gtfs, you must have tripped on some issues).
Just out of curiosity, did you consider other algorithms, like CSA? It’s been a while I’m out of the algorithmical stuff, so I’m just wondering pros and cons of different algorithms.
I agree. That’s our choice, mostly because of our background as service provider (we usually charge by time) it’s in our comfort zone while we are uncomfortable in marketing and trying to get 1000 recurring paying customers. Everyone is different.
And yes, I’m frustrated that living from doing FOSS is hard. And it is also hard to spend only 1 day/week to do smaller contributions…
Oh, that’s sad. Placemark was a very nice as it was for collecting geographical objects where the associated data is well structured. This is always a hurdle when integrating the generated data into other systems.
My coop has been working with something resembling to placemark: https://cocarto.com but our business model is not to sell it as a SaaS (which is always very difficult, and requires a lot of capital to reach enough customers) but sell a service to companies and administration around it. That’s why it’s FOSS from the beginning.
For now Capitaine Train the only carriers we are connected to that stop in Austrian stations are Deutsche Bahn and Trenitalia. Only those stations are in the database.
Once we connect to ÖBB and Westbahn, we will need a more important cover.
I am on that list since a while :) We met at the Okfn-conf in Geneva.
I am waiting until we translate the blogpost and our page in English before talking about that on the list.
Pieter Colpaert alreday complained about uri/linked data ;)
Indeed the data is incomplete yet. Bear in mind that the data comes from a specific use on https://www.capitainetrain.com That is why many countries are poorly covered (yet! we plan to eventually cover whole Europe).
There is no magic to find the UIC code, sorry… Sometimes it is in OpenStreetMap, sometimes we get it from a rail operator… But it is not a required value, so you can add it with out the station.
`is_suggestable` means that the user can input the station on capitainetrain.com. Leave it false for now ;)
The idea behind the name vs. info is that name is the station as it is locally known.
Info adds any information extra information to help to find which station it is (that includes translations, “Central Station” for people not understanding „Hbf“, disambiguation between similar names…)
Wow! I didn’t know about those ids, thank you. However it would be some work to match the stations.
What call the db_id is called IBNR as Internationaler Bahnhofs Nummer
(I work at Capitaine Train who published this data)
It is true. This database has not the pretension to have all the stations in Europe. It has all the stations where we can sell tickets to.
As we connect to more carriers, the database will expand. But it is a long process.
Dijkstra’s algorithm is well known in computer science, but as other comments say it, Google uses a much more advanced algorithm.
Furthermore the complexity O(n×log(n)) we know dates from the 80’s. Many years after Dijktra’s original article.
They say so in their announcement: “and for the stationary storage market”
A huge growing market will be batteries in homes. Germany is trying to push it to go from 30% of photovoltaic self-consumption up to 70% (when the sun shines, people usually are away at work). The excessive electricity is sold to the network.
This requires between 5 and 10kWh storage capacity (compared to the 50+kWh of a Tesla) for a single family home.
The current price is about 20€cts/kWh for the storage over the whole lifetime. So it is not economic yet, but it should be within a few years and I hope that Tesla will contribute to it.
Solar costs about 15€cts/kWh and electricity from the network is around 25€cts/kWh. When solar will reach 10€cts and storage 10€cts/kWh, the market will be very important.
