Visualising Traffic Patterns

A guy named Pedro M Cruz has put together an interesting video. It's cool to see a neat graphical interpretation of something so mundane as traffic.

Pedro's explanation:

'One month (October 2009) of traffic information (1534 vehicles) is condensed in a 24h day. The arteries are colored in a way capable to represent average traffic speeds (the greenish and cooler represents high traffic velocity, and the reddish and hotter, corresponds to sluggish traffic). There is a visual emphasis on areas where the traffic is predominantly slow'.

Location: Lisbon, Portugal.

This video could do with some music though.
