The Segment Analysis provides three Metrics that describe trips through corridors:
- Speed of trips
- Duration of trips,
- "Free Flow Factor," which measures congestion.
Free Flow Factor is a ratio of the average trip speed for the Day Part to the maximum average trip speed for the segment in any hour during the entire Data Period. This means that when the Free Flow Factor is close to 1, there is little congestion on the corridor. The lower the Free Flow Factor, the greater the congestion.
