Isochrones

The Isochrones project is an application that calculates areas accessible by public transport and on foot only, within a certain time frame, starting from a location in Switzerland at a given time.

This information is important for planning or analyzing the public transport network offer and was obtained using open data from the Swiss Federal Railways (SBB/CFF).

The isochrones are made available through a website that allows visualization of the results.
