Abstract:It is well known that urban form is highly correlated with the evolution of transportation systems. In order to develop planning tools that are responsive to the complicated interaction between transportation and land use, it is helpful to identify the typical characteristics of the development of urban form. The relationship between transportation, land use and urban form is complicated by feedback relationships. Understanding the three-way dynamics between land supply, urban development and travel demand is a first step toward understanding these aspects in the transportation planning process. Using the Des Moines metropolitan area as a case study, this paper begins to examine and quantify some of these relationships. The purpose of this paper is to examine how urban form accommodates transportation systems and vice versa at a conceptual level. This is accomplished through a review of past studies on urban form and transportation from both design and transportation planning literature. The case study demonstrates the relationships between urban population density, travel pattern, residential and commercial distribution, using an interface between MapInfo and Tranplan. Following the characterization provided in the case study, suggestions for further strengthening of the relationship between land use and transportation in travel planning models are recommended.
