An ALife approach to modeling virtual cities

This paper proposes a novel method that enables automatic modeling of virtual cities. The method makes use of L-systems to generate road networks and the genetic algorithm (GA) to generate building layouts. The road networks are composed of two types of roads-linear flow systems which are generated by using the Tree L-system and cellular networks which are generated by using the Map L-system. A generation procedure for road networks and building layouts is described. Some experimental results of generated road networks and virtual cities are also shown.
