- departure time / day
The isochrone curves are computed using actual transportation data (tram and buses) from transport.data.gouv.fr
The front-end (github repository) is a small Vue.js app that uses
leaflet to display the map and the isochrone curves.
The back-end (github repository) is built in Python and relies mainly on
geopandas. The data source is and ensemble of static files (GTFS format) that describe the public transportation available on a given day and time of day. This data source is dynamically analysed to create the isochrone curves that describe how far one can travel during a given duration.
