A study into whether social networks can help change travel behaviour. A bit underwhelming really…interviews with two developers, a focus group, and an online survey with 141 users. And inconclusive results: “…They seem likely to increase awareness of the impact of travel behaviours and of more sustainable alternatives. This may not lead to a direct change in travel behaviours, but it potentially impacts on attitudes and values that could change travel behaviours in the longer term.”
Curiously, this paper appears to suggest that people with more members in their social network travel more.
