Health impacts of the Cambridgeshire Guided Busway; CGB
Commuting and Health in Cambridge is a quasi-experimental cohort study of adults who travel to work in Cambridge, established with the aim of evaluating the Cambridgeshire Guided Busway which was opened in 2011.
The study aims to assess the magnitude, nature and population distribution of changes in the travel behaviour of commuters who travel to work in Cambridge associated with the opening of the Cambridgeshire Guided Busway. It additionally seeks to identify, explore and explain the wider health impacts of any observed changes in travel behaviour, specifically in terms of changes in overall physical activity, wellbeing, sickness absence, and carbon emissions. Four annual waves of survey data (2009-2012; baseline n=1164) are complemented by detailed behavioural measurement in subsamples using Actigraph and Actiheart physical activity monitors, global positioning system (GPS) receivers and household travel diaries, four waves of qualitative interviews, an intercept survey of busway users and an ethnographic participant-observation study. A fuller description is available on the study web page and in the study protocol paper.

Evaluating the effects of environmental and policy interventions on active living and understanding related patterns and mechanisms of behaviour change.
The study was established to address the following research questions: Is investment in new high-quality transport infrastructure associated with an increase in the use of active modes of travel? What are the wider health impacts of changes in travel behaviour in terms of overall physical activity, wellbeing, sickness absence and carbon emissions? What are the determinants of the use and uptake of active modes of travel? How are any changes in travel behaviour distributed in the population? How are any changes in travel behaviour brought about and experienced? Are changes in travel behaviour sustained over time?.
Adults aged 16 and over who travel to work in Cambridge from within a radius of approximately 30 kilometres.
Field work completed, analysis and further preparation and development of detailed behavioural measurement datasets ongoing.
No longer recruiting.
The final dataset includes approximately 5000 survey responses as well as over 1300 person-weeks of georeferenced physical activity data, over 800 household-weeks of travel diary data and over 120 interviews.
Data collection began: May 2009
