I. Introduction
Three-dimensional traffic animation is of great significance in the field of disaster impact prediction and evaluation. This has grown over years to be an important area of research. Institutions related to weather forecast, disaster control, civilian safety protection as well as insurance companies have benefited from the successful implementation of such techniques. A traffic system plays a principal role in a disaster animation scene because (a) it is a component in which human beings are directly involved via their vehicles and thus any disruption in it affects human life closely; (b) it provides prior information about safe routes for evacuation when the area is affected by a disaster. Although traffic animation is also applied in other situations like urban planning or transportation management, these areas usually do not cover all the requirements of a typical disaster management system. Urban planning [1] usually targets on a high definition demonstration and overlooks interaction details while transportation management [2] focuses on vehicle interaction but may overlook visual effects.
