Abstract

Fast transportation routes such as railways and highways in a city have an effect on locational decision making and urban spatial structure. This paper investigates optimal locational pattern of focal points in several ideal cities with fast transportation routes using conditional facility location models that minimize total travel distance. Optimal solutions with seven patterns of fast transportation routes are compared for two types of location model: traditional p-median model and flow-demand p-median model. Results shows that fast routes significantly affect locational patterns, especially for flow-demand models. Travel speed on fast routes also plays an important role in deciding optimal location. We observe that rectangular lattice and orbital route can reduce the concentration at the center and that hierarchical structure of facility location in flow-demand setting.
