For Public Transportation, Hanoi Wants to Ban Bikes by 2025

Vietnam’s government plans to rid the congested streets in downtown Hanoi of motorbikes by 2025 to make room for more buses and metro lines — but residents areless than open to the change.

There are currently around half a million cars and 5 million motorbikes on the Hanoi streets, and the government estimates that economic growth will increase those numbers to 1 million cars and 7 million motorbikes by 2020. The streets are already crowded, and air pollution is bad enough that the Real Time Air Quality Index classifies the city as “unhealthy.”

“The traffic situation in Hanoi will become extremely complicated in the next four to five years,” Hanoi City Chairman Nguyen Duc Chung said at a public development meeting. “So we really need a timely solution to this.”



That solution includes building highway, bridges, tunnels, bus stations, along with doubling the number of buses and adding six new metro train lines by 2030. But it also includes banning motorbikes from the city center within ten years. In a city where less than 10 percent of residents use public transportation, the transition would be extreme.

In addition to not wanting to part with an integral mode of transportation, The Guardian reports that some see the move as unfair to those who cannot afford their own cars. Many are skeptical that the construction of the first two new metro lines will happen on schedule by 2020, since they have already faced delays.

Fighting Motorcycles and Waiting for Metro Lines in Hanoi

Hanoi, a city with more motorbikes than households, has to contend with heavy congestion and frequent traffic accidents. In recent years, studies have named it among the worst cities in Asia for air pollution. In May this year, Vietnamese media reported that the US embassy’s air quality monitor in Hanoi registered a “hazardous” spike in particulate matter, reportedly reaching a level seven times that recommended by the World Health Organisation.

Though the government hopes the metro can tackle both traffic and environmental issues at once, the project has faced numerous delays and setbacks. What’s more, convincing Hanoians to give up their motorbikes could turn out to be the biggest challenge yet.

In 2008, more than 80% of journeys in the city were carried out by motorbikes and scooters – and a fast-growing share of the population is opting for cars. Currently there are roughly 4.9 million motorbikes and scooters on Hanoi’s roads. The use of bicycles, once the dominant transport mode in the city, decreased dramatically as motorbikes and cars became more popular: in 1995, 47% of journeys were made by bicycle; in 2008, the figure had dropped to only 3%.

Hanoi’s Transport Plan aims to increase the share of public transport from the current low figure of 9% of trips, to above 60% by 2030, by which time Hanoi is slated to have six new metro lines and three Bus Rapid Transit (BRT) lines. But the ambitions get even steeper. Last month, Hanoi’s Party Committee outlined plans to ban motorbikes from the downtown area by 2025, in line with improved public transport. A total downtown ban of the vehicles would require a huge lifestyle shift for most residents – and put an enormous amount of pressure on the new metro system. None of the locals I speak to regard the 2025 plan as feasible.

Two-wheelers on CNG - Piloted in India

Scooters and motorcycles that run on non-polluting natural gas could be on India’s roads one day, if a pilot project involving 10 such two-wheelers launched on Thursday proves successful. The 10 two-wheelers retrofitted with compressed natural gas (CNG) systems are the first of 50 such vehicles which will be released in Delhi within a month. Emissions and efficiency of these vehicles will be closely monitored. Union environment minister Prakash Javadekar and petroleum minister Dharmendra Pradhan launched the pilot in the national capital.
