The migration model is a component of the TELMoS land-use model. It forecasts the pattern of migration of households between the different sub-regions of Scotland. (Movements within sub-regions are forecast in the urban model.) The critical inputs which can vary as a result of different transport schemes are those from the urban model, ie job opportunities and housing costs. Job opportunities are a strong incentive to migration. Housing costs are a weak disincentive.

There is no direct link from transport to migration: better transport does not in itself encourage migration (indeed, it may discourage migration if better transport allows increases in long-distance commuting). However, if better transport leads to employment growth, or allows better access to employment, that will tend to encourage migration into the area affected.
