From 2019, the NTAS has replaced the questions that were included in the British Social Attitudes survey. This survey is asked of respondents to the National Travel Survey (NTS) who have consented to being contacted for further studies.
Multiple survey waves are conducted each year, allowing a mixture of core questions as well as additional questions similar to an omnibus.
Responses to surveys about other transport modes include micro transport are below.

The British Social Attitudes (BSA) survey is NatCen’s longest running survey, being carried out annually since 1983. More details can be found at the dedicated BSA website.
The department included transport related questions as part of the BSA between 2002 and 2018, with the final year being a cut-down set of questions. From 2019 onwards, many of these questions are included in the National Transport Attitudes Study (NTAS).
Data from the ONS ‘Opinions’ survey, the ‘British social attitudes survey’ and the NatCen omnibus are available from the UK Data Service.
Omnibus surveys are operated by a number of social research providers. They allow clients to buy space in a ‘rolling’ public survey to ask a small set of questions for a limited time period. An omnibus survey will typically feature a standard set of core questions that are of interest to all clients (covering personal and household characteristics), alongside topic-specific questions funded by individual clients. They are therefore a low-cost and flexible method of running small-scale public surveys.
Omnibus surveys use stratified sampling techniques and are usually weighted to ensure that results are representative of the population at large. Both the NatCen and ONS omnibus surveys use random probability sampling (without replacement) and are conducted ‘face-to-face’ at the respondent’s household using computer assisted personal interviewing (CAPI).
The attitudinal statistics collected using the ONS ‘Opinions’ omnibus survey are Official Statistics and are produced in line with the relevant code of practice. The department’s view is that all statistics which are not designated as National Statistics are robust and have been produced to a suitable standard.
Indeed, the ONS ‘Opinions’ survey methodology is comparable to that of other ONS surveys whose results are published as National Statistics. However, DfT reports from this survey have not been put forward for National Statistics assessment.
