Proposed hike follows doubling of metro ticket price earlier this year.
The cost of travelling on the Cairo metro network is expected to increase in 2018, following negotiations between the Cairo Metro Company and Egypt's transport ministry.
The announcement of the new ticket fares is expected following the completion of new ticket gates at the city's metro stations during 2018.
In March this year ticket fares on the capital's metro system doubled from EGP 1 to EGP 2 for a single journey, regardless of distance.
It is not known yet how much the price increase will be, or how it will be calculated, however Egypt's transport minister Hesham Arafat recently indicated that the fares would see a gradual increase, eventually reaching EGP 4 by the last quarter of 2018.
Launched in 1987, Cairo’s underground metro system is one of the oldest in the Middle East and Africa. More than 3.5 million passengers use the three lines across the greater Cairo area every day.
