VieBra - The coalescence of two cities 

Postgraduate Program URBAN STRATEGIES, 2006 - 2007 / Universität für angewandte Kunst 

Vienna - Bratislava 

The land in between Vienna and Bratislava, historically used to seperate people, can become the land of an emerging trans-national metropolitan area. 

To simulate growth and densification i use the "Game of Live" algorithm, due to the analogies with the rise, fall and alterations of a society of living organisms. Its a simulation of real live processes. The Game provides an example of emergence and self-organization. 

The aim of this work is to set up a method suitable for modelling the dynamic evolution of urban centres.

Rules of Conway's Game of Life:

1. Any live cell with fewer than two live neighbours dies, as if caused by underpopulation.

2. Any live cell with more than three live neighbours dies, as if by overcrowding.

3. Any live cell with two or three neighbours lives on to the next generation.

4. Any dead cell with exactly three live neighbours becomes a live cell.

first test - the initial configuration representing the existing settlements of Vienna and Bratislava: 

>Vienna and Bratislava don't realy grow towards each other

second test - the initial configuration are the "empty fields" within the test territory: 

>The evolution of urban centres of the Vienna Bratislava region can be observed 

(=concept of central places)

The investigation of the surface is based on the measurement of 3 different qualities:

R- sealed surface

G- protected nature surface

B- cultivated surface

The association of the surface qualities to the parametric colour model of "RGB-colour" leads to a visualisation of the existing conditions. The color becomes the code of the surface-properties.

The urban multiplier - Danube shipping

The infrastructural intervention of a Danube-bypass between Vienna and Bratislava and one common harbour can create impulses for urban and economical development.
