According to forecasts from the United Nations Secretariat, more than 60 percent of the world population will live in urban areas by 2030. With a total world population expected to reach 8.2 billion in the same year, the pressure that this enormous mass of new urban dwellers will cause on transportation infrastructures will be unbearable. It will cause the conversion of large portions of land into urbanized areas and require vast investments in transportation infrastructures, raising concerns about public expenditures, as well as about traffic congestion and safety, environmental pollution, and land consumption.1

The land consumption (land take) phenomenon is the increase of artificial land use at the expense of natural and semi-natural land use, therefore it includes sealed and unsealed areas such as urban green areas (European Environmental Agency, 1997).

Generally unpresented urbanization and urban expansion characterized by demographic shift from rural to urbanized areas with a resultant rapid increase in absolute and per capita land consumption rates has been recorded over the last several decades. According to United Nations (2012), global urban population increased from 1.35 billion in 1970 to 3.63 billion in 2011, a 169% increase. The United Nations (2019), World Urbanization Prospects 2018 revision states that globally, 55% of world’s population live in urban centers as of 2018. The report further states that in 1950, 3% of the world’s population was urban, and by 2050, 68% of global population is projected to be urban. Of particular concern is the fast pace of urbanization recorded in low-income countries including those in sub-Saharan Africa. In 2018, the proportion of the population living in urban areas was 32% in low-income countries, and is projected to reach, on average, 59% urban by 2050.
