Livable "Complete" Streets for Panama

I noticed this initiative by The National Complete Streets Coalition (via Wired Magazine) which seeks to create guidelines for more livable urban streets. The definition of “livable” in this case is that the streets are accommodating to all modes of transportation; autos, pedestrians, bicycles, and public transportation.
This is something which I believe should be adopted by Panama in order to fix the increasing problems of traffic, pollution, and an unlivable urban environment.
