Live map of public transport in Belgium

Author here! Thanks for posting the app!

Two notes on what you are looking at:

Not every vehicle is a live position. STIB-MIVB and TEC publish vehicle positions and those are shown as received. De Lijn and NMBS/SNCB do not, so their vehicles are computed from the timetable and corrected with the delays they do publish (GTFS-RT). Each marker is tagged live, computed with delay, or computed, and the computed ones are drawn dimmer.

All data is open data. The four operators publish through one federal portal (data.belgianmobility.io) under CC BY 4.0: GTFS for timetables and route geometry, GTFS-RT for delays, alerts and positions where available. NMBS ships no route geometry, so train paths are routed over Infrabel's open track network.

This is not specific to Belgium. Nearly every country publishes public-transport open data in the same formats, and I was able to locate feeds for most European countries. A map like this can be built for almost any of them!

Happy to answer questions on the data or the simulation :)

I do see some isolated improvements whenever I travel to Germany (mostly to Frankfurt, but what is pain other than Frankfurt am Main), but yeah I sympathize here, and do hope the pushes toward better systems continue

And yet pretty accurate :)

I don't want to be negative here, just asking out of curiosity. Does anyone actually use apps/services like this? Why would it be useful?

Normally when I want to get somewhere I just use local public transport navigation app which calculates the route and shows me estimated time of when my tram or bus arrives (taking into account its GPS data). Why would I need to know live position of every vehicle in the city?

Nevertheless, cool project!
