Abstract

Active travel such as walking and cycling has potential to increase physical activity  levels in sedentary individuals. Motorised car travel is a sedentary behaviour that  contributes to carbon emissions. There have been recent calls for technology that will  improve our ability to measure these travel behaviours, and in particular evaluate modes and volumes of active versus sedentary travel. The purpose of this pilot study is to  investigate the potential efficacy of a new electronic measurement device, a wearable digital camera called SenseCam, in travel research.
