DELTA regional models

The regional model application of DELTA adds three more sub-models dealing with:

  • migration between different urban areas
  • the location of investment
  • the pattern of production and trade.

The investment and production/trade sub-models form the Regional Economic Model, which can be used alone. A full urban/regional DELTA application integrates all three of the sub-models with the urban modelling, as shown in Figure 3.
