As part of a wider initiative in urban regeneration, a new five-mile section of the M74 motorway has recently been opened in Glasgow. This ‘natural experiment’ provides an opportunity to evaluate a major change in the urban environment, which may have positive or negative effects on the health and wellbeing of those living nearby.
The aim of this study is to increase our understanding of how and why changing characteristics of the urban environment does, or does not, affect how people feel about living in their neighbourhoods, where they go in those neighbourhoods and how active they are. This is important because there is currently little clear public health evidence to guide decisions about investing in expensive urban regeneration projects of this kind. Indeed, an independent public local inquiry advised the government of the day not to proceed with this particular intervention because it ‘would be very likely to have very serious undesirable results’ for local communities.
Our research will test the competing claims for and against the intervention, and will therefore help inform future policy and planning in other parts of the UK where population growth is anticipated or urban redesign is proposed.
We have built on our previous baseline study (conducted in 2005) by investigating changes in travel behaviour, physical activity, perceptions of the neighbourhood environment, wellbeing, and road traffic casualties in a follow-up study between 2013 and 2015.
We surveyed adults living close to the new motorway and comparing them with those living in two matched comparison areas of the city: one where there has been a motorway since the 1960s, and one that has no motorway. We then invited some participants to spend a week wearing unobtrusive monitors (accelerometers and GPS receivers) to provide objective data about their activity patterns, because we are particularly interested in where people go in their neighbourhoods and how this may have been affected by the changes in their environment. We also interviewed a smaller number of local residents and other key informants face-to-face to explore their experiences. We have now finished collecting data for all parts of the study.
