This technical paper was written with undergraduate geography students and instructors in mind. Its primary objective is to introduce readers to the first of urban simulations and to provide materials for utilizing simulation models. Contents are interdisciplinary oriented and contain seven chapters showing how simulation techniques may be utilized. Chapter one describes urban environment as a dynamic, everchanging, behavioral system of spatial and non-spatical forces. In chapter two, spatial dynamics of the urban environment are examined. A description of simulation is explored in chapter three, while chapter four introduces computer simulation. The fifth chapter presents a model of spatial diffusion. Chapter six discusses gaming situations. In chapter seven a collection of urban gaming situations are presented and discussed. The first of three games, LOCO, ECOLOC, and URBLOCK; focus specifically on the locational behavior of attitudes in the urban environment. The last two games, Urban Politics and Welfare, are primarily non-spatial in character and deal with a wide range of issues prevalent in the urban environment. (Author/SJM)
