Show HN: Seattle Traffic Congestion Map, in 3d

This is the normal traffic map that most folks use: http://www.wsdot.wa.gov/traffic/seattle/

And this map adds a third dimension: http://seattletraffic3d.herokuapp.com/

Oh right, that's why I live and work on Capitol Hill... Neat! :)

Kinda cool, but it bottoms out at 0 degrees of inclination for all Y coordinates in the bottom half of the window, which is a really useless perspective. How about bounding the range of angles, between something like 30 and 90 degrees?

What does the height of the traffic line mean? It's not very clear.

Higher = slower traffic, the original map used 4 colors to show traffic speed, I kept those colors and made corresponding heights.

Pretty cool, what did you use to build it? The navigation was a little difficult to grasp, might be more intuitive with a click and drag interface, or something with buttons i.e. google earth.

Thanks! I used Three.JS for the 3d rendering, Rails for the rest. Good idea on the click/drag UI, I'll think about that for v2!

I came across three.js and was actually looking for it randomly today, very cool.
