Virtual cities are emerging into the cyber space and other virtual environments such as web sites and computer games. Virtual cities are usually made from camera images or 3D data of real cities; however, it may be interesting to create completely new type of cities in the computer. We started a virtual-city project with road networks generated by using L-system. In this paper, we propose a method to generate road networks taking geographical environments into account as a factor that affects the geometrical and topological shape of road networks. The method makes use of an L-system modified so that each production rule may be applied referring to the geographical environments and depending its probability. We actually produced new road networks to compare with real ones.
