Mid West Regional Model

The Mid West Regional Model (MWRM) is one of five models that comprise the Authority’s Regional Modelling System. The MWRM is centred around Limerick City and includes 428 internal zones covering Limerick, Clare and North Tipperary counties with travel between these zones and the rest of Ireland represented by 26 external zones. The zone structure of the MWRM is shown in the images below, click on each image to see it in more detail.


The base year of the model is 2012 and it represents an average weekday with five separate peak periods modelled;

  • AM peak (07:00-10:00);
  • Morning Inter peak (10:00-13:00);
  • Afternoon Inter peak (13:00-16:00);
  • PM peak (16:00-19:00); and
  • Off peak (19:00-07:00).

The model covers all surface access modes for personal travel and goods vehicles including private vehicles (taxis and cars), public transport (bus, rail, Luas, BRT, Metro), active modes (walking and cycling) and goods vehicles (light goods vehicles and heavy goods vehicles).
