Centre for Climate Change and Social Transformations: Cardiff Travel Survey, Wave 5, 2025

The Cardiff Travel Survey is a longitudinal survey that aims to (a) establish current and previous (before the coronavirus outbreak) travel habits; (b) explore how travel-related attitudes, social norms and perceptions change over time; and (c) examine the interplay between individual (perceptual) and environmental (infrastructural) factors in travel mode choice, in particular in relation to the uptake of active travel such as walking and cycling in the City of Cardiff, Wales.

The Cardiff Travel Survey 2025 (Wave 5) is an opportunity sample that was collected in 2025 (n=470) by the Centre for Climate Change and Social Transformations (CAST), and is the fifth of a longitudinal series of surveys to be held annually for the duration of the centre. Data for the Cardiff Travel Survey 2025 were collected between 29 April 2024 and 29 June 2025.
Participants of the 2023 and 2024 Cardiff Travel Survey who consented (n=1,324) were recontacted via email to invite them to take part in the 2025 survey, of which n=90 were undeliverable. The survey was not further advertised, and no other recruitment methods were used.

The survey was hosted on the Qualtrics online survey platform and was available in both English and Welsh. Inclusion criteria were that participants had to be at least 18 years of age and live in or travel regularly to Cardiff.

The English version of the survey was completed by 500 respondents and the Welsh version by 10 respondents. Incomplete responses (n=29), defined as those without any answers beyond socio-demographic, were also removed from the dataset. A further 11 respondents did not complete the first section on current travel behaviours and were also removed. This left a final sample of n=470 adults. Participants were asked to create a unique code that can be used to match this survey to previous and future surveys without revealing their identity.

Main topic areas of the questionnaire were: Demographics, Travel behaviours, Physical activity, Physical health and mental wellbeing, Perceptions of infrastructure and environmental quality, Travel-related social identity, Attitudes to active travel, Active travel-related social norms, Support for active travel policies, and Unique ID."
