Are you in Toronto and interested in transportation? I'll be teaching transportation modeling to calculate travel times and accessibility to destinations in #rstats using #r5r ! Free workshop April 8 @ UofT https://www.eventbrite.ca/e/bousfield-urban-accessibility-r-crash-course-tickets-1284533186339?aff=oddtdtcreator

Some days are just better.

It is rewarding to see an analysis go brrrrrrrr after spending a lot of time trying to solve some problems in my pipeline, automating many steps, figuring out how #r5r and #r5py work, and circumventing some hard-coded problems of R5.

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.

#rJavaEnv and #r5r #rstats downloads periodically see bumps in daily downloads. Someone somewhere is conducting a workshop on #accessibility...?

#rstats since it's release is early-mid September 2024 #rJavaEnv (ekotov.pro/rJavaEnv/) is averaging 500+ downloads per month. It's your trusty companion for #r5r, #RSelenium, #openNLP and 100+ other #Java dependent packages. Install Java in one line of code + use with #targets #ReproducibleResearch

Having this basic understanding of how both geographical systems can be connected, we can improve spatial analyses that revolve around proximity and accessibility, e.g. using the #r5r package @UrbanDemog

Last week @tenkahen and @dhersz delivered at @CASAUCL a bilingual workshop on accessibility modelling using both #r5py (#Python) & #r5r (#rstats)

r5r: https://ipeagit.github.io/r5r/
r5py: https://r5py.readthedocs.io/

Doing transport accessibility analysis has never been so easy :)

Thanks for the brilliant @CASAUCL students who were eager to learn accessibility modelling with #r5py & #r5r. My first workshop combining #Py…
