| Comparisons between areas close to and more distant from network | Linking routine data from National Travel Survey and Health Survey for England to areas close to and distant from a cycle pathway | Outcome measures: Differences between areas in amount of walking and cycling Differences between areas in self-reported levels of physical activity | Linking of routine data to postcodes and from this to areas of completed network paths | May not be possible to obtain routine survey data by postcode Need to be able to adequately adjust for potential sociodemographic confounding factors |
