2 MOBILITY
Mobility is a relatively straightforward concept. In the transport context it means to be able to move about physically. In other contexts it is used to mean moving economically or socially between classes.
To achieve mobility, a person needs the physical means to move about. These include legs, skis, wheelchairs, horses, automobiles, public transport and special transport, to name but a few. For effective mobility, appropriate infrastructure must be available for the vehicle or other means of mobility. Thus a footway that provides unrestricted mobility for pedestrians would prevent mobility for people in wheelchairs if it had kerbs that were not dropped at appropriate places. A metre of snow prevents mobility for a person without skis.
In addition to the physical means of mobility being available, a person is only mobile if they have funds to pay the cost of travelling, documentation to authorise travel (if needed), and knowledge of the existence of the means of travel and of how to use it.
