Modeling for Urban Crowd Daily Behavior Based on Human-Earth Relationship

With the development of the urbanization process, the spatial-temporal behavior of the urban crowd is becoming focus of the research in urban transportation, environment and evacuation etc. The model of the spatial-temporal behavior of the crowd has wholly turned to micro and detailed from traditional mean. Traditional GIS data model rarely considers the behavior of human activities in micro-geographical environment, and it lacks consideration of surface features possessing various affections to the human. Individual daily travel behavior often depends on the change of the urban surface features´ spatial distribution. These space objects have different functions (such as home, school, hospital), different states (mobile car, fixed house), which are directly bound up with individual spatial-temporal behavior. Therefore, the human-earth relationship is an important part during the construction of urban crowd´s spatial-temporal model. In this paper, the author raise the method for modeling of individual and group´s spatial-temporal daily behavior, through constructing urban crowd´s human-earth relationship model, which is based on the exploration of the method that used by complex human and land information´s acquisition and processing. In addition, a prototype system has been built a prototype system for preliminary application experiment, in which the urban crowds´ spatial-temporal behavior simulated.
