Multiagent land-use and transport model for the policy evaluation of a compact city

Land-use strategies such as city compaction are the basis for creating livable communities with more accessible land-use patterns that reduce automobile dependency. In previous studies the various advantages of the compact city have been proven, especially from environmental perspectives, but there still remain major questions, such as how the compact city can be induced and whether it can bring a higher quality of life. The authors' main objective in this paper is to answer these questions by using a multiagent land-use transport model to represent the interaction of agents' locations, the effects of mixed land use, and the agglomeration merits or demerits of agents. This model is used to examine the effectiveness of policy measures aimed at achieving a compact city from the viewpoint of urban physical compactness, total trip length, energy consumption, and the social welfare of residents.
