Procedural urban modeling of population, road network and land use

This paper introduces an urban simulation system generating urban layouts with population, road network and land use layers. The desired urban spatial structure is obtained by generating population map based on population density models. The road network is generated at three spatial levels corresponding to the road hierarchy. The land use allocation is based on rule-based algorithm. And global and local parameters are designed to guarantee the flexibility and modification of urban layouts. The expected results are urban layouts suitable for academic scenario analysis.
