Traffic in Lisbon condensed in one day

This post presents several experiments (piked between a total of more than 20 generated artifacts) that map 1534 vehicles, during October 2009 in Lisbon, leaving route trails and condensed in one single day. The artifacts are animations of traffic’s evolution in Lisbon during a fictitious 24-hour period (from 0:00 to 23:59). Below are the three most relevant results and metaphors.

Traffic clots

Perhaps the strongest visual metaphor — an organism with circulatory problems. When the traffic is slow, the red clots start appearing. Watch video on Vimeo.

Aesthetic deviation

The following artifact is in its essence an aesthetic deviation that brings a visual emphasis on the main traffic routes. Pencil and paper. Darker arteries traduce intense traffic. Watch video on Vimeo.

Searching for emphasis in sluggish areas

In the next artifact the color of the arteries change with the speed of the vehicles. Rapid transit arteries are drawn with greenish and cooler colors, while the sluggish ones are reddish and hotter. Traffic intensity is mapped in the thickness and brightness of the arteries. When a certain path has a very low velocity, its covered area gets filled — the intention was to bring an emphasis to the areas with major traffic issues (low speed). The white dots represent the vehicles themselves. Eye candy, eye candy. Watch video on Vimeo.

These visualization were developed in the context of CityMotion and my master thesis at DEI/FBA.
