I developed an app to track buses and subways in Rennes, France, in real time and want to plug in a bunch of data sources to enhance it further.
Hi everyone, this is my first post here. I’ve developed a small app, a project I'd put on hold for at least two years, to track buses and subways in Rennes, France, in real time (sorry, the app is in French). Stack SvelteKit x Maplibre and DeckGL The base (and the theoretical version) are built on pre-processed GTFS data, then the real-time position uses API calls for GTFS-RT, and between polls I interpolate based on the speed limit for each segment It’s a really fun project, heavily inspired by the incredible Mini Tokyo 3D app. It makes me want to plug in a bunch of data sources, since Rennes has some great OpenData, just to get closer to a virtual twin Anyway, if you want to play around with it a bit, you can check it out here: [https://nahelou.github.io/rennes-transit-map/](https://nahelou.github.io/rennes-transit-map/) Thanks !
