A Middle Filter is a special Zone used in the O-D with Middle Filter Analysis, similar to a "Select Link" study. The Middle Filter must be a Zone marked as Pass-Through. It may have a direction. The Middle Filter Analysis is calculated for all trips starting in or passing through the Origin Zones, then passing through the Middle Filter Zones, then ending in or passing through the Destination Zones. A Project may have multiple Middle Filter Zones. Each Middle Filter Zone is analyzed separately.
