I'm interested in studying human movement (any type of transportation except aerial), specifically related to health.
I would assume most of this data is owned by one possible creators/collectors of it, such as telecom companies (which record their cellphone client's position on the cell "handover" procedure).
I've searched around the web and have not found data sources yet.
Do any other open data sources, in which I could obtain at the very least trends of human movement, exist? For now I'm not interested in international migration. Any country is OK.
What I'm interested in is the "movement" people usually do, their commutes, and their most usual movements. I'd use this data to research it jointly with case data (of multiple different diseases) and see if there's a correlation.
