Tuomas Väisänen 📼🧟‍♂️I am wondering if the generation of an <a href="https://vis.social/tags/isochrone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#isochrone</a> is slower or faster compared to generating a grid-based travel-time matrix with <a href="https://vis.social/tags/R5R" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#R5R</a> or <a href="https://vis.social/tags/R5py" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#R5py</a>.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.

Tuomas Väisänen 📼🧟‍♂️Apparently, the easiest way to calculate an <a href="https://vis.social/tags/isochrone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#isochrone</a> for travel times is to use <a href="https://vis.social/tags/R5r" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#R5r</a> in <a href="https://vis.social/tags/Rstats" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Rstats</a>. 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 <a href="https://vis.social/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a> to generate hundreds of isochrones across Europe.

Khurram Wadee ✅Forgive the recent apparent obsession (I’d call it a fascination) with the <a href="https://mastodon.org.uk/tags/cycloid" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cycloid</a> but I’ve just discovered something I’d not heard of before. It is also called a <a href="https://mastodon.org.uk/tags/TautochroneCurve" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TautochroneCurve</a> or <a href="https://mastodon.org.uk/tags/Isochrone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Isochrone</a> curve, which means that a particle starting from any location on the curve will get to the <a href="https://mastodon.org.uk/tags/MinimumPoint" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MinimumPoint</a> at precisely the same time as a particle starting at any other point.<a href="https://mastodon.org.uk/tags/Dynamics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Dynamics</a> <a href="https://mastodon.org.uk/tags/Kinematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Kinematics</a> <a href="https://mastodon.org.uk/tags/Mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mathematics</a> <a href="https://mastodon.org.uk/tags/AppliedMathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AppliedMathematics</a> <a href="https://mastodon.org.uk/tags/Mechanics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mechanics</a> <a href="https://mastodon.org.uk/tags/ClassicalMecanics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClassicalMecanics</a> <a href="https://mastodon.org.uk/tags/WxMaxima" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WxMaxima</a> <a href="https://mastodon.org.uk/tags/FreeSoftware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeSoftware</a> <a href="https://mastodon.org.uk/tags/MyWork" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MyWork</a> <a href="https://mastodon.org.uk/tags/CCBYSA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CCBYSA</a>

Denis 🌏Dear <a href="https://hachyderm.io/tags/lazyWeb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lazyWeb</a> : does anyone know of a website/app like <a href="https://www.commutometer.com" rel="nofollow noopener noreferrer" target="_blank">https://www.commutometer.com</a> that would provide bike travel times? (commutometer is public-transit focused, which is great, but I'd like to also use bike as an option)(yes, I can check point-to-point bike times with google maps, but a isochrone map would be handy for overview)<a href="https://hachyderm.io/tags/transit" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#transit</a> <a href="https://hachyderm.io/tags/publicTransit" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#publicTransit</a> <a href="https://hachyderm.io/tags/BostonMA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BostonMA</a> <a href="https://hachyderm.io/tags/bike" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#bike</a> <a href="https://hachyderm.io/tags/BikeTooter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BikeTooter</a> <a href="https://hachyderm.io/tags/apartmentHunting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#apartmentHunting</a> <a href="https://hachyderm.io/tags/isochrone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#isochrone</a>
