future cities

Norway's capital city is a leader in transportation innovation. Oslo has already eliminated nearly all street parking in the city center, and bike transportation is flourishing.

In 2018, it will turn several streets into pedestrian zones, allowing only limited use of motorized vehicles. The city said it could also introduce stricter regulations in 2019 that ban nearly all cars from its center.

Other cities, including Mexico City and Paris, have restricted vehicle use on certain days to limit pollution and traffic.
