Oslo. Laszlo Ilyes Cars are no longer welcome in downtown Oslo.

Oslo plans to ban all cars from its city center by 2019, Reuters reports.

It will also build more than 35 miles of bike lanes by 2019 and invest heavily in public transport.

The permanent ban will affect the 350,000 or so car owners in the Norwegian capital.

Oslo's car ban is the largest of its kind, says Paul Steely White, the executive director of Transportation Alternatives, an organization that helped install New York's Citi Bikes and advocates for car-free cities.

"The fact that Oslo is moving forward so rapidly is encouraging, and I think it will be inspiring if they are successful," he tells Tech Insider.

The car ban in Oslo will reduce pollution and make it a safer city for those on foot.

"We want to make it better for pedestrians, cyclists. It will be better for shops and everyone," Lan Marie Nguyen Berg, lead negotiator for the Green Party in Oslo, tells Reuters.

Madrid set a similar precedent last year, when the city announced an ambitious plan to kick cars out by 2020. Madrid's ban, larger than Oslo's, will cover 500 acres of the city. Other European cities have worked toward similar objectives, but not to this scale and speed.

Paris banned cars from its major landmarks, like the Eiffel Tower and Notre Dame Cathedral, last month. If commuters in Milan leave their cars at home, the government will reward them with public transit vouchers. Copenhagen introduced pedestrian zones in the 1960s, and car-free zones slowly followed over the last half-century.

Oslo's auto ban may mark a shift in our thinking around cars, White says. When cities move away from private transportation, they can rededicate that space to public parks, sidewalks, and cafés.

The problems created by cars are many.

Traffic in London today moves slower than the average cyclist, and drivers in the U.K. waste 106 days of their life searching for parking spots. Commuters in Los Angeles spend 90 hours per year in traffic.

Pollution aside, cars are actually the most inefficient way to move through a city. Car bans could solve that.

"Having cars inside a dense city center is the equivalent of putting a large dinner table in a small studio apartment," White says. "In the space it takes to park a car, you can park 15 bicycles."

White predicts large car-free zones will eventually happen in the U.S. "Because Oslo is moving forward on such an aggressive time table, the world will be watching and seeing how it goes," he says. To follow Oslo's lead, White says other cities need to provide more bike lanes, sidewalks, buses, and subways.

Options like these will improve everyone's commute.

"What a human and wonderful thing: to be able to walk down the street and feel like you're a first-class citizen," White says.
