Intervention:
Nine studies (two good, six moderate, and one poor quality) were identified examining behavioural interventions. All studies aimed to increase active travel through education and promotion and were non-infrastructural in nature. Intervention features varied between studies. Education features included distribution of educational material and resource packs, seminars, and training of eco-travel coordinators. Promotion features were celebration events, led walks, distribution of promotional material and individualised travel marketing strategies. Other behaviour change techniques were used in some studies (such as prompts and goal setting).
Evidence quality:
Overall, the majority of studies showed an effect in favour of the intervention across a range of active travel outcomes (such as purposeful walking and cycling). However, it should be noted that four studies out nine (one high quality and three moderate quality) did not report whether their findings were statistically significant.
Generalisability:
Four studies were conducted in the UK, three in Australia, one in the USA and one in Japan. Therefore, the interventions could be partially generalisable to Wales, but the contextual environment of the different countries should be considered.
If proceeding with this intervention:
It is suggested that a detailed examination of the evidence base is conducted, taking into account intervention context, to support design and implementation. A thorough evaluation of impact should also be conducted.
