TAPAS travel survey

A growing body of literature suggests likely positive impacts of travel policies and built environment strategies to increase walking and cycling. We are undertaking a travel behaviour survey in Barcelona, Spain, which includes questions on physical activity, mode choice, and perception of the environment. The study investigates factors related to commute mode choice in Barcelona, with a focus on barriers and motivators of cycling. It includes an analysis of perceived and objective measures of the environment on mode choice, a study of effects of the BICING bike sharing program on bike commuting in Barcelona, and an assessment of the contribution of active commuting to overall physical activity.

We conducted a pilot and validation study of the travel questionnaire (November 2010-February 2012) which included collecting objective measures of geographic location and physical activity levels associated with respondents’ activities. We recruited 36 volunteers who were administered the travel survey and were monitored during 5 days with cell-phone based technology that incorporates global positioning systems (GPS) and accelerometers to measure physical activity. One aim of the study was to pilot-test the cell-phone based technology, called CalFit, developed by engineers and environmental health scientists at the University of California, Berkeley also partners in this project.

We will start recruitment for the main travel survey in June 2011, aiming at interviewing 400 cyclists and 400 non-cyclists.
