In bike-friendly Copenhagen, the Social Democrats' candidate for mayor tried to win over drivers by calling for more car parking.
In elections this week, she was trounced. For the first time in 122 years, a Social Democrat won't lead Copenhagen. The new mayor is a socialist from the Green Left.

Ups and downs belong to #academia. Two funding applications out of three came back negative. Really frustrating.
I also applied for a new research position, and came up with a clever (IMO) research plan in a short time, so I am very happy with that.

It is quite nice to have my favorite team connection back after a lengthy renovation, just in time for the winter season when cycling gets a bit more tricky (and unpleasant).

Creating a #centroid is not as trivial as you might think!
If you are dealing with regional population data, the locational difference between a regular geometric centroid and a population-weighted centroid can be vast!

AI won’t replace planners, but it is reshaping how we imagine, design & govern our cities. The barrier isn’t tech, it’s mindset.

How can we accurately map where people live and work when they frequently cross national borders? Traditional surveys miss complexity, mobile network operators data are hard to get across borders, and individual social-media traces are sparse—yet social media is inherently transnational.

I also presented yesterday some preliminary work on exploring structural changes in the #Erasmus student mobility network in #Europe.
Student mobility has rebounded, and the structure has changed, with larger regional cities becoming more relevant, and Brexit removing the UK's relevance in Erasmus.
