The colors mimic and signify Motorway / Trunk / Primary / Secondary / Other. You can click on the features to get a popup with those links. It's a GeoJSON-fed vector layer. Let me give some background on how the data is prepared (and kept up to date if I get it to work reliably): 1 A local us.o5m[1] file is updated using osmupdate[2] 2 From that, a file with just those objects last edited by the redaction bot is filtered using osmfilter[3]. 3 This file is compared with the previous run, an osc is derived using osmconvert[4]. 4 The osc is applied to a PostGIS database that was initially populated with the result of the first run of step 2. The script can be found at https://gist.github.com/3257796 if you're interested.
