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.
