THE GEOGRAPHY OF TRANSPORT SYSTEMS
| Size | Larger | More throughput and less warehousing. |
| Facility | One storey; Separate loading and unloading bays | Sorting efficiency. |
| Land | Large lot | Parking space for trucks (often not necessary due to high throughput); Space for expansion. |
| Accessibility | Proximity to highways | Constant movements (pick-up and deliveries) in small batches (often LTL); Access to corridors and markets. |
| Market | Regional / National | Less than 48 hours service window. |
| IT | Integration | Sort parcels; Control movements from receiving docks to shipping dock; Management systems controlling transactions. |
The setting of large distribution centers, often part of distribution clusters, has been a dominant trend, particularly among major retailers such as Wal-Mart, Target and Home Depot.
