The aim of the study is to assess health data (heart rate variability, blood pressure, blood glucose, particulate matter pollution) and travel characteristics (length, duration and type of commute) on the way to and from work from members of the universities in Hannover (Germany).

Active mobility, (i.e. moving around using the own physical strength) has positive sustainability effects. The physically active way to and from college is a great untapped resources for health promotion. The aim of this sub-project is to examine the way to university in order to assess its effect on individual health depending on the means of transport.

In order to determine the status quo and changes in mobility behavior the investigators will use movement trajectories using smartphone apps or inexpensive trackers in a larger cohort, as well as more specified health measures including overweight status, blood pressure, blood glucose concentration, lack of exercise, particulate matter and risk of accidents in a smaller sub-cohort.

By linking this data with the personal characteristics surveyed in other sub-projects, an evaluation of the individual health status and the expected health benefits depending on the route to work can be created. This represents the database for identifying certain groups of people or status groups who could particularly benefit from targeted promotion of an active commute.
