modelling, simultaneous estimation, traffic system

The main aim of dynamic traffic control is not to increse the capacity of whole traffic network but to increase troughput and thus to alleviatte the influence of bottlenecks. All types of dynamic traffic control strategies need information about the current traffic situation, i.e. about the actual traffic flow, such as queue lengths. Unfortunately, they are hardly measured. The queue lengths have to be estimated from available data by a suitable estimation method on the basis of proper traffic model. The main aim of this chapter is twofold. First, the focus will be directed on the design and indepth description of the traffic system model. This model whould be designed to properly describe the behaviour of a traffic flow on an arbitrarily complex micro-region. Second, the designed model will be validated and thus the methods for the model validation will be presented and applied.
