EFFECTS OF EMPLOYMENT AND RESIDENTIAL LOCATION CHOICES ON URBAN STRUCTURE: A DYNAMIC STOCHASTIC SIMULATION

The pattern of home-to-work linkages in urban areas is affected by household mobility decisions. This paper describes a dynamic stochastic simulation model designed to illustrate the effects of mobility decisions on urban structure. The major feature of the model is the representation of household changes in employment or residential locations or both. The sequential process of the decision to move and the search for and selection of new location is specified. The role of accessibility in this process is an important consideration in the model, which allows quick execution of simulation experiments. Experiments consist of alternative input assumptions involving factors such as city size, numbers and locations of job centers and dwelling units, initial pattern of home-to-job linkages, moving rate, and importance of accessibility in selecting new locations. Two types of experiments are presented. The first examines the dynamic properties of the model by varying the initial pattern of home-to-job linkages and the mobility rate. The major conclusion is that there appears to be an equilibrium pattern of home-to-job linkages that is independent of the initial configuration and mobility rate. The second type of experiment involves the variation of the importance of accessibility in the mobility decision process. The results show that the pattern of home-to-job linkages varies in the expected way with changes in the decision process. /Authors/
