The City of Mass MobilityIn 2020 over 50 percent of the worlds population will live in cities on just 3 percent of the worlds land mass. Increasingly over crowded cities are becoming ever more congested and as a result living spaces are becoming smaller and our quality of life is becoming worse. To com-bat this we want to design a city of the future that improves flow and circulation to provide a freely mobile city that does not compromise public or private spaces. We shall consider all of the various circulation systems within the cities, including pedestrians, public forms of trans-

port, along with any necessary support infrastructure.

Velocity Vortex12 Fall 2012 Marina NicollierArchitectural Design III ARCH 553

In the city, as a user goes from the exterior to the interior of a building their velocity changes; a pedestrian goes from a low ve-locity to a high velocity, and a car goes from a high velocity to a low velocity. This inver-sion of velocities creates a direct separation from the exterior to the interior. Within this project a user velocity is kept at a constant as one moves through the building and then as they leave their velocity is increased. This allows for the user to enter the building and experience it without a disconnect from the exterior.

A spiral also simulating a vortex is a shape and form that is unlike any other; it is rarely referred to as geometry, but rather as energy. The form is also seen in plant growth patterns. This allows for the maxi-mum number of petals to grow in the least amount of space. The spiral is not so much a shape as the evidence of a shape forma-tion.
