Abstract
Many researchers advocate transit oriented development or compact city concept. However, it is necessary to obtain a rational reason on urban policy by quantitatively grasping an effect of transportation mode on city growth. In this reason, we developed a simple simulation model that can compare the differences between automobile-oriented and transit-oriented cities, and clarify the difference among city forms by transportation mode. Following a theoretical model development, a series of simulation runs are tried. The model allocates people who commute to CBD from residential zones along a transportation corridor. As a result of many simulation runs, it is shown that automobile requires much more traffic space than transit.
In this paper, the improvement on the model is proposed using Linear Programming. It is an improvement for the purpose that the model can be applied to more general city forms. Through the trial, we confirm that the solution of LP model exists.
