The following simulation describes the growth of suburbs in the United States through the twentieth century. It describes and explains the reasons and the results of suburb growth.
Flexibility is an important quality of this simulation; by adding or taking out agents in simulation the user can observe the changes that will take place because of userıs interference. In other words, we give the user a unique opportunity to play with history.
At the beginning of the simulation, there is an "inner city" and a number of small villages on periphery. As the simulation starts running, people will move to the cityıs outer edges. Then, they are followed by developers who build more houses in suburbs. The developers will also build new roads that will connect the "inner city" with the suburbs. Gradually, the suburbs will expand and their quality will enhance too. More and more people will move to suburbs, as a result the "inner city" starts decaying.
There are several flexible agents, which the user can play with. By putting and extracting these agents the user is able to create his/her own scenario of suburb growth. The first and the "most flexible" agent of the simulation is developer. He is the one who actually creates the bulk of suburbs. In our simulation the developer can create up to five new houses on the open spaces. The more houses there are, the more people move from city to suburbs. After the first generation of "immigrants" a new generation comes to suburbs. The new generation then puts up more beautiful houses with yards and trees.
The increased movement of people from the city to suburbs requires new means of transportation. Here, a new flexible agent, car, comes on stage. The user can change the number of cars that in its turn, would affect the number of trees in suburbs. We made this dependence between the number of cars and the number of the trees because of the direct link between the pollution cars cause and the trees, which reduce the pollution. Now, when we have enough cars we come up another problem roads to drive on. Developers come to help again. Not only do they put up more roads, but they also create new ones.
Other than the agents we have already described above, there are also such agents like "pink houses", " new houses", "gangsters" and "man 2" that though do not play a crucial role in simulation, are an important part of it. They add to the simulation, complement the overall impression of the project and make it ecstatically pleasant for the user.
In the end, we hope you will learn more about the suburb growth in the United States and at the same time enjoy the simulation as an interesting game, where you are the boss.
