Used to indicate duration of a route that is bus, route=ferry, railway=funicular, aerialway=cable_car etc). The duration does not include any possibly required waiting time. Applied to relations or ways. The duration for a relation should contain the sum of durations needed for the individual relation elements.
Most useful where the route has a clear beginning and end. Should only be applied where normal routing algorithms and traffic analysis cannot figure out how long it takes (highways is the most obvious example).
It's uncertain how to show duration between stops. Comments are welcome.
The recommended format is the simple 'hh:mm' format for hours and minutes. OSRM or GraphHopper support either 'mm', 'hh:mm' or 'hh::mm::ss'. Be aware that values less than one hour has been entered as simple integer minutes. This practice is discouraged as its ambigous with integer hours.
A more formal alternative is ISO 8601:
