Jamming In LA

Nathan Yau tenses up:

Waze, in collaboration with Gray Area Foundation and Nik Hanselmann, visualize 24 hours of traffic in Los Angeles, a subject that holds a bitter spot in my heart. 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.
