Running Urban Microsimulations Consistently with Real-World Data
Abstract We present concepts and methods to cope with the enormous data needs of urban microsimulations. In the first part of the article, we adopt a process-oriented perspective on relocation, activity participation, and transportation and then refine this perspective in the microsimulation context. The second part of the article considers the parameter and state estimation problem. First, the different time scales of an urban system are identified and a rolling horizon framework for its continuous state estimation is developed. Second, the parameter estimation problem for an integrated urban microsimulation problem is investigated. The operational difficulty of jointly estimating all parameters of the urban model is met with two different approaches: the decoupling through estimated process interactions and the use of response surfaces and metamodels to mathematically approximate intractable, simulation-based processes.
