In 1987 that population stood at 10 million residents, not counting the two million or so commuters who came into Cairo every day to work.<ref name=Salama1987/>{{rp|11}} The capacity of Cairo's public transport infrastructure was around 20,000 passengers/hour, which increased to 60,000 after the construction of the metro.<ref name=Salama1987/>{{rp|14}}
