Blue is close. Dark red is the edge. The road network density just shows itself.

I am wondering if the generation of an #isochrone is slower or faster compared to generating a grid-based travel-time matrix with #R5R or #R5py.

Both would get me the result I want in slightly different ways. I need to calculate the travel times to all somewhat major border crossing points in Europe. Calculating 30, 60 and 90 minute isochrones (private car) for Finland's 12 over-land points is taking over an hour in R5R, which is not optimal given that there are 1800+ points across Europe.

Apparently, the easiest way to calculate an #isochrone for travel times is to use #R5r in #Rstats. Trouble is, I've only had one beginner course of R, so I am a bit scared of my ability to troubleshoot anything.

Apparently there is nothing similarly fast in #Python to generate hundreds of isochrones across Europe.

Forgive the recent apparent obsession (I’d call it a fascination) with the #cycloid but I’ve just discovered something I’d not heard of before. It is also called a #TautochroneCurve or #Isochrone curve, which means that a particle starting from any location on the curve will get to the #MinimumPoint at precisely the same time as a particle starting at any other point.
