The Travel Survey for Northern Ireland is required to provide a comprehensive picture of personal travel behaviour by people living in private households in Northern Ireland.  The sample is therefore designed to provide a representative sample of households in Northern Ireland. 

The sample for the Travel Survey consists of a systematic random sample of 1740 addresses selected from the Pointer Database. The Pointer Database is managed by Land & Property Services (LPS) and Ordnance Survey Northern Ireland (OSNI) with input from Royal Mail. This is the most up-to-date listing of private households and is made available to the Northern Ireland Statistics and Research Agency for research purposes.  People living in institutions (though not in private households in such institutions) are excluded.

A total of 145 addresses are selected for interview each month for the Travel Survey. Each member of each household is asked to provide information about journeys made in a pre-selected seven-day period, known as the Travel Week. 

The information for the survey is collected in the following stages:

  • A placement call where members of the household are asked a series of questions about household composition, type of vehicles, travel habits and use of public transport. 
  • A travel diary is left with each respondent to be completed during a selected "travel week".
  • Finally a pick-up call - our interviewer will then call at the address to pick up the completed diaries.
