Rationale - what it means and why it is an important measure
|
|
Different transport modes place pressures on the environment. Public transport saves valuable space and energy compared to private transport, and has positive health benefits. Transport congestion is associated with air pollution, accidents, reduced productivity, and general frustration for the population.

|
How it is compiled, what data are needed
|
This indicator is measured by transport mode: proportion of trips undertaken by private cars, train or tram, bus or minibus, motorcycle, bicycle, walking or others.
This indicator should be measured annually.

Other comments / background
|
|
Data on transport modes are usually obtained through specific transport surveys. These data may be difficult to obtain, especially disaggregated data. If data cannot be provided for the level of detail above, please provide data on: private motorized vehicles; trains and trams; buses and minibuses; non-motorized vehicles.
