I do recognize I have large gaps of data missing. This was written as a hypothesis on travel and randomness. To support kids activities in a southern US city, random time/source/destination of drivers is removed. Most people have to drive to the same location at the same time to send their kids to school or other activities. Thus, the event yesterday added more randomness to the travel patterns by removing the kids activities.

I don't have real-time flow of all data, thus I could be completely wrong. All I have for traffic data is a few Google traffic maps.
