Blood Drive: Traffic Expressed As A Cardiac System

Today I stumbled across this lovely visualisation by Pedro Cruz who took the Lisbon traffic system and turned it into a ‘living’ cardiac system. He took the number of vehicles on the road and their average velocity to be the variables controlling the thickness, the color and the length of the vessels.

The image below is one of Pedro’s earlier attempts to map the traffic using swarms and particles.

I would recommend viewing other visualisations on his site including this really cool one on the changes in the size of historical empires over time
