Visualizing Freeway Traffic in the San Diego Region

These two animations were created using California's Freeway Performance Measurement System (PeMS) data to demonstrate the average weekday traffic flow and speed on the freeway system during the month of October 2006. The graduated circles represent the traffic flow expressed as vehicles per hour passing through a segment of freeway. The color of each circle represents the traffic speed in miles per hour. The animations demonstrate the changes in traffic conditions throughout the day based on five minute intervals.
