A future in which everyone travels in driverless flying cars may still dominate the popular imagination, particularly when it comes to media and marketing hype. But if we are to meet the UN's Sustainable Development Goals (SDG) on sustainable cities and communities, a more revolutionary (albeit more low-tech) picture will unfold, in which people are moving freely and swiftly - but not by car.
Reducing our dependence on petrol cars is not only better for the planet and our individual wellbeing, it will pave the way to a better future for our cities. From improving mobility and ensuring civic participation in how cities are designed, run and experienced, to public health and strengthening the social fabric that will make our communities more resilient, a shift towards fewer cars can help our cities not only survive, but thrive.
The process may not be simple, but there is a practical and easy strategy that can help people see streets differently: temporarily taking cars off the street.
How to get people out of their cars continues to be a global challenge. Even in cities where public space and public transport are safe and reliable, this can be difficult; it is especially so in places where these amenities are unsafe, unaffordable and unreliable. This is where temporary interventions such as car-free days can unlock a whole new approach to movement and mobility.
In the mid-1970s, Colombia's capital city, Bogota, saw the birth of what would become a global movement to make streets safer, more inclusive and more appealing to city dwellers. It is called Ciclovia, often known as 'open streets' in English-speaking countries, and entails the creation of car-free routes throughout the city every Sunday and public holiday.
The swarms of cyclists that take over city streets on these occasions is a real spectacle. Even though the impact on mobility patterns has not yet been fully understood, it is clear that in places like Bogota, Ciclovia was the genesis of bicycle infrastructure in the city and perhaps the country. Culture and environment has helped the movement to grow bicycling in Colombia: people have relied on the bicycle to travel for more than 100 years and professional cycling is a source of national pride. This might not be the case everywhere, but the worldwide frenzy around urban cycling makes this an opportune moment to try car-free street programmes and put them to the test.
