The science of visitor management in parks and protected areas: from verbal reports to simulation models

Visitor management in parks, wilderness and other protected areas requires information about visitor-environment interactions and, particularly, the distribution and flow of visitors in space and time. Such information is usually sketchy and based largely on the verbal reports of visitors. A review of recent psychological and neurological research and theory suggests that traditional verbal survey methods cannot in principle provide an adequate basis for models of human landscape navigation. We argue for more use of direct observation of visitor movements and the utility of travel simulation models. Simulation modelling of visitor flow can be helpful in making monitoring programs more efficient, in fine-tuning existing management programs, and in assessing the likely consequences of alternative future scenarios We review early efforts to simulate the flow of recreation use, describe several current modelling efforts and conclude with suggestions for a research and development effort.
