The ability to provide an accurate view of a region of interest is standard among existing tracking systems. The extension of this capability to include accurate projections of the targets to future times increases the complexity of the problem. However, this ability to predict future locations is an important problem due to the inherent time latency that is present from sensor to shooter. Because of this, a major requirement of the tracking system is that it must be able to use available information to accurately pr edict future target locations. The focus of this paper is to describe an improved state estimation technique that incorporates road information by using a Variable Structure IMM. Furthermore, this approach will identify and account for stopped or stationary moving targets. Finally, some preliminary performance results will be presented.
