Means of Transport and Population Distribution in Metropolitan Areas: An Evolutionary Analysis of the Valencia Metropolitan Area
2022
Carmen Zornoza-Gallego
The purpose of this research is to find out how transport modes shape the configuration of a metropolitan area in terms of population. Evolutionary analysis is undertaken to ascertain the impact of mobility on population distribution over a number of stages. The case study analysis puts the spotlight on the Valencia Metropolitan Area (Spain) over a long period of time, from 1900 to 2021. The research focuses on quantification, first in terms of how different means of transport affect population distribution, and subsequently, on the time gap between the emergence of a means of transport and its potential in distributing the population. Results show that the prevalence of the means of transport in structuring a metropolitan area has varied over time. At first, trains and trams played a major role in shaping the urban area while, in more recent eras, cars have remodelled the urban space. It was found that municipalities which did not have a railway service had very low, or even negative, increases in population until 1981. By contrast, since then, they have outstripped the increases in municipalities with rail connections. The time gap between the emergence of a means of transport and its potential to distribute the population is quantified in terms of decades. Automobiles took less time than trains and trams to have an impact on population distribution. These results can be understood as an indicator of the length of time needed to change previous dynamics and can be used to guide new policies in the field.
