Abstract:

A computer simulation study was made of the role of barriers in structuring human activity patterns in space. Certain abstract barrier situations were investigated using Monte Carlo simulation in the context of spatial diffusion problems. Within this framework the effects of shape and function of barriers were examined, and results indicated that 1 shape is the most important characteristic of a barrier, 2 the spatial range of a barrier is determined by the mean information field of the individual or unit element of the activity under consideration, and 3 time was found to be an essential part of both the spatial movement and its measurement. Drawing upon these results, two simple theoretical models of barrier situations were constructed and compared with their real world counterparts. The degree of correspondence indicates that this approach promises to develop into a fruitful line of inquiry. Author
