Children are a kind of indicator species. If we can build a successful city for children, we will have a successful city for all people.

In Bogotá, our goal was to make a city for all the children. The measure of a good city is one where a child on a tricycle or bicycle can safely go anywhere. If a city is good for children, it will be good for everybody else. Over the last 80 years we have been making cities much more for cars' mobility than for children’s happiness.

A premise of the new city is that we want a society to be as egalitarian as possible. For this purpose, quality-of-life distribution is more important than income distribution. [And quality of life includes] a living environment as free of motor vehicles as possible.

The essence of the conflict today, really, is cars versus people…We can have a city that is very friendly to cars, or a city that is very friendly to people. We cannot have both.

Urban transport is a political and not a technical issue. The technical aspects are very simple. The difficult decisions relate to who is going to benefit from the models adopted.

God made us walking animals - pedestrians. As a fish needs to swim, a bird to fly, a deer to run, we need to walk, not in order to survive, but to be happy.

An advanced city is not one where even the poor use cars, but rather one where even the rich use public transport.

A bikeway is a symbol that shows that a citizen on a $30 bicycle is equally important as a citizen on a $30,000 car.

The importance of pedestrian public spaces cannot be measured, but most other important things in life cannot be measured either: Friendship, beauty, love and loyalty are examples. Parks and other pedestrian places are essential to a city's happiness.

We need to walk, just as birds need to fly. We need to be around other people. We need beauty. We need contact with nature. And most of all, we need not to be excluded. We need to feel some sort of equality.

In every detail a city should reflect that human beings are sacred and that they are equal.
