An interpolating model for land-price data with transportation costs and urban activities

It can be inconvenient to use published land-price data with urban lattice data in analyses of urban activities, because such land-price data are limited to assigned plots in an urban area. This paper is an attempt to provide a model for interpolating the limited data. The proposed model is based on the concept of transportation costs in a wider sense than simple monetary costs. To improve the acceptability of the model, urban activities in each place are also incorporated into the model. This paper will first introduce the concept of transportation costs in a wider sense to describe accessibility to the city center. Next, it constructs a model of land prices in the Tokyo Metropolitan area, based on a theoretical consideration of the relation between transportation costs and land prices. We improve the model by incorporating uban activities to make it reflect regional characteristics. -from Authors
