They can also potentially reflect individual characteristics if the data used are differentiated accordingly (e.g. by number of jobs available to people in a certain age range or income group). For instance, while transport planners tend to focus on the transport component of accessibility, urban planning practice has often placed more emphasis on metrics reflecting land use factors. Practice has shown that breaking this silo-type of thinking promotes a more holistic approach and could be achieved by using a combination of indicators and conducting coordinated analysis by relevant authorities.
