Following a thirty-fold increase in car traffic in the city of Hanoi (Vietnam), a metro network is being built to decrease pollution, improve public health and productivity.

In Hanoi, motorbikes are the main way of transportation with 600 motorbikes for 1000 inhabitants. With only 1000 buses, the bus network is currently the only public transport and the number of passengers increased 30 times over the past 6 years.

With a population of 6.2 million in 2012 (8 million in 2020), the city needs to address the urban transport crisis with the creation of the Hanoi metro. The aim will be to have one in two journeys by public transport in 2020.

Our Greenfish team will work on the Nhon-Hanoi Station metro, a line that will transport 157,000 passengers a day in 2018, 428,000 by 2020 and 750,000 by 2030. The project will save around 20,000 T eq. CO2 between 2010 and 2030. It is expected to halve local polluting emissions by 2020. The number of roads accidents will decrease from 3500 to 2100 thanks to the project.

The line will run from the west of the city to the south. The 12.5-kilometre line, of which 8.5 kilometres will be elevated and 4 underground, will include 12 stations and is scheduled to enter service at the end of 2021. It will be the first urban underground structure built in the Vietnamese capital.
