Simulating Interactions Between Land Use, Transport and Environment

This paper describes how the project Integrated Land-Use Modeling and Transport System Simulation (ILUMASS) embedded a microscopic dynamic simulation model of urban traffic flows into a comprehensive model system that incorporated both changes of land use and the resulting changes in transport demand as well as their environmental impacts. The land use modeling is entirely microscopic and includes models of demographic development, residential location, firm life cycles, business relocation and construction of dwellings and non-residential floor space. To test the land use model the very detailed transport and environment models were temporarily replaced by an aggregate transport model and less detailed environmental impact models. The paper outlines the land use submodels and their integration into the ILUMASS model and presents selected scenario results and concludes with a discussion of the advantages and limits of microsimulation.
