I want to get accurate data on walking behaviour (particularly related to public transport use), such as the distances and routes taken.
A relatively easy method would be to use an app for people's smartphones to track their location.
I have tested a few apps, such as Moves, but in my experience the tracking often tends to be inaccurate - especially regarding the microscale on which walking takes place.
I wonder what other people's experiences are regarding the use of travel behaviour-tracking apps, or other (non-smartphone) tools that might help getting insight into this walking behaviour?
