Hi HN, Isochrone maps show areas which are reachable within a given time limit. Specifying them for car journeys is straightforward, but scheduled public transport add lots of factors which affect how far you can go, e.g. what time are you setting off?, what day of the week is it?. There are already ischrone generators out there, but none of them let you set all the relevant parameters - so I made one.

This is great!! How do you figure out the pedestrian range?

Do you do loads of individual queries for different ranges from each train station? Are these pre-cached?

Each time someone generates a map I calculate the time to each reachable station then use the valhalla routing engine to generate an isochrone centred on the station with the remaining time.

Cool idea. Funnily enough, I wasn’t able to recreate my commute. With all the parameters, my commute isn’t available… maybe I walk to fast

Or maybe there's a bug... I might make the walking speed adjustable.

I won’t mind providing some additional data!
