An Integrated Metropolitan Model Incorporating Demographic-economic, Land-use and Transport Models

Department of Urban and Regional Planning, Chung-Ang University, San 40-1, Deduck-Myun, Ansung-gun, Kyunggi-do, Seoul, Korea 456-800, mjjunl{at}naeri.cc2.cau.ac.kr

This paper formulates an integrated metropolitan model which captures full intersectoral and interspatial relations as well as impacts on transport networks within a metropolitan area. To achieve this, the proposed model consists of three components: multizonal input-output linkages; land forecast models; and transport demand forecast models. Given the model structure, the proposed model can estimate economic impacts by type of secondary repercussions (indirect, and induced spillovers), by industry type and by zone. In addition, the proposed model will forecast the size of land by land-use type and by zone and estimate changes in traffic volumes on transport networks due to an urban policy. Moreover, the three components of the proposed model can be easily linked with GIS, presenting all the zone-specific information generated from the model on maps.
