National Travel Survey (NTS)
Module of QNHS Quarter , 2012, 2013 and 2014 On travel behaviour of respondents One of most comprehensive household studies of travel patterns ever to be conducted within the State In 2014, detailed information on travel collected from 10,382 respondents comprising 18,031 journeys
4
NTS continued CAPI interviewing – on waves 2 to 4 of QNHS sample
The information collected included the following: number of journeys made reason for journey mode of transport used duration of each journey distance travelled Only travel within the island of Ireland, made by residents of the State

NTS continued 2011 Census of Population POWCAR (Place Of Work Census of Anonymised Records) POWCAR - definitive source of data on travel to work, school and college NTS results – are for a particular quarter - may not be fully representative of the year as a whole Care should be taken when interpreting the results, especially if extrapolating to annualised results Also seasonality note of caution

NTS – key definitions and descriptions
Journey – one way course of travel from A toB for the purpose of carrying out a specific activity at location B. Location could be a single premise or a complex of premises Return trips recorded as separate journeys Journeys must have: Commenced in the travel reference day (but may end the following day) Been at least 100 metres in length (approx one minute walk) Comprised exclusively of domestic travel (all stages of foreign travel were excluded) Not an integral part of respondent’s routine employment Mode - where a journey consists of more than one mode of travel, the main mode of travel is the mode of travel used for greatest distance Travel reference period is 4am to 3:59am – allows capture of information for respondents who finish work or return from leisure activities after midnight Data collected over 24 hour period

NTS – key definitions and descriptions (continued)
Travel Reference Day To ensure that data is collected for all 7 days of the week, each participant in the NTS is assigned a selected 'travel reference day ‘- maximum of three days prior to the day of interview Wednesday through to Saturday interviews - travel reference day was the immediately preceding day Monday interviews - .30% of Monday interviews were assigned at random to the immediately preceding Friday, 42% to the immediately preceding Saturday and 28% to the immediately preceding Sunday. Tuesday interviews- 17% were assigned at random to the immediately preceding Sunday and 83% were assigned to the immediately preceding Monday Excluded the business related travel of professional drivers (e.g. bus and taxi drivers) and other occupations where travel is integral to the role (e.g. postal delivery workers) NTS journey purpose of 'work' includes both commuter and business travel Excludes the business related travel of professional drivers (e.g. bus and taxi drivers) and other occupations where travel is integral to the role (e.g. postal delivery workers)

Users of NTS Data Used to compile statistical indicators for journey purpose and modes of travel Universally accepted necessity for better transport data to underpin transport policy making and monitoring of key programmes, including Smarter Travel Help monitor implementation of existing transport policy and will inform future transport initiatives With regular surveys any shifts will be detected earlier and allow policy approaches to be more responsive in future Measure of demand for personal transport within the State Spending on Transport in 2014 was €1.1 billion

Future of NTS Next survey – Quarter 4 2016 No change basis
Household Survey Development Project – transformation programme for QNHS CSO - meet user demand for travel data while simultaneously reducing the response burden, minimising the required inputs Does the change being captured by the survey necessitate an annual survey?
