Construction of Virtual Town and Driving Simulation in It Using Graphics Workstation

Abstract

In this paper, we describe an integrated driving simulator that enables us to construct a virtual town interactively, and to drive through the town in real time. This simulation system is composed of three functions : road generation, virtual town construction, and driving simulation. We first specify road elements on a graphic terminal, either on the basis of road maps or freely. Then, we construct a virtual town with various elements, such as a road with lanes or signals, buildings, and traffic flow. These elements are automatically generated by using road elements. Finally, we can drive in the vitrual town.
