iConnect is a quasi-experimental study of the travel, physical activity and carbon impacts of Connect2, a UK-wide programme of constructing new walking and cycling routes in local areas, conducted as part of an interdisciplinary research consortium.

The MRC Epidemiology Unit leads:

(a) the iConnect core module, which comprises an evaluation of the Connect2 study sites at Cardiff, Kenilworth and Southampton in which three annual waves of adult population survey data (2010-2012; baseline n=3516) are complemented by in-depth case studies and qualitative interviews with stakeholders and participants
(b) the iConnect Travel to School case study at a secondary school in Cheshunt, Hertfordshire.
A more detailed description is available on the study web page and in the study protocol paper for the core module.

Research areas:
Evaluating the effects of environmental and policy interventions on active living and understanding related patterns and mechanisms of behaviour change.

Research purposes:
The study was established to assess the impacts of infrastructural interventions on travel behaviour, physical activity, carbon emissions and energy use at individual and population level and to explore why these interventions are (or are not) effective, in what ways, for whom and in what circumstances.


(a) in the iConnect core module, adults living within approximately five kilometres of one of the three study sites
(b) in the iConnect Travel to School case study, pupils at the secondary school.

Field work completed, analysis and further preparation and development of datasets ongoing.

No longer recruiting.

The final dataset for the core module includes approximately 7000 survey responses.
