Throughout human history, people have settled the land based on two fundamental desires, to be both in motion and in place. Cities as we understand them today were formed when the necessary movement of people and vehicles through them began to crystallize in the design of distinct rights of way. And as in response, in the enabling of stasis, human comfort and security, pleasure and production, in the form of distinct blocks, lots and buildings of various kinds.
The physical character and livability of human settlements has always existed in the intersection between the design and maintenance of this grid of potential, a simple binary system of Urbanism: blocks defining streets for mobility, streets defining blocks for inhabitation.
The particular design of these two key ingredients of city making has changed radically in pattern and scale over time, adapting to human needs. Their interdependence has not. We can experience it in all kinds of beloved existing traditional places: in Villages designed for hand cart service, in towns organized around the movement of animal drawn carriages, in cities built to the scale of motorized vehicles, in regions supported by transit.
