This video animates "the pain that is Los Angeles traffic" by using a map with colorful dots representing traffic, general hazards, and police. Makes you wonder how a video of New York traffic would look in comparison.
It starts at 5pm, right in the middle of rush hour, slows down in the late hours, and then of course picks up again around 7am, as people commute to work. Red dots indicate high levels of traffic and green dots indicate hazards, which I assume are accidents. Watch the day unfold in the video below.
