The city is creating a "revolutionary" network of cycle superhighways, which, according to City Lab, bear "smooth pavement, good lighting, separation from traffic, safe road crossings, rain shelters, and air pumps" and will cover 290 miles of the city and its surrounds by 2018.
The Greek capital, along with cities like Beijing and Mexico City, has tried a system of "road space rationing" whereby cars with certain number plates are banned from travelling in the city centre on certain days of the week.
A similar scheme to Athens' was implemented in the Honduran capital in 2008, in which owners of vehicles had to register one day of the week when they would not drive into the city. If their car was spotted on the roads, the owner would be fined up to $40.
Despite an expected growth in population, city planners in Helsinki want to make it as easy as possible to walk everywhere by creating a "network of dense, walkable neighbourhoods that are virtually car-free" by 2050, according to Fast Company.
City planners in Milan introduced a scheme whereby tracking devices are placed on cars and owners are rewarded with a public transport voucher if the car stays parked at home between 7.30am and 7.30pm.
Ahead of the crucial climate summit due to start in the city next month, mayor of Paris Anne Hidalgo decided to make a statement: the city would ban all cars from its city centre for a day. On Sunday 27th September, there was an unusual calm on the streets and Parisians reported that the sky above the French capital was bluer than they'd ever seen it before.
While certainly not a new innovation, Venice is perhaps a perfect example of a city that can function without automobiles. Citizens in Europe's largest car-free area use the city's famous waterways to make their way around instead.
