Transport Rates and Network Structure
Transport rates can be influenced by the network structure since
it shapes the quantity of traffic at different links and nodes and
therefore the potential for economies of scale.
- Diffused network. An extended service (left side) would
be characterized by low frequencies and smaller shipments, resulting
on high rates on many segments of the network. This is particularly
the case for peripheral nodes.
- Centralized network. A centralized network structure (right
side) has less links and a consolidation of flows at hubs. It results
in lower rates on several segments that have a higher frequency
of service, notably those between hubs.
