Telematics systems development has already become a necessity due to the limited capacity of the road infrastructure. Transport can thus be better managed; also relevant information can be provided directly into the vehicles. Based on the development of communication technologies, namely „car-to-infrastructure” (C2I), the requirements are continuously rising – not only on the on-board units (OBU) but also on the infrastructure equipment and solution of particular modules for traffic management systems as well. The paper focuses on the design and simulation of control system in an intelligent unit on infrastructure that will be able to respond to the actual traffic situation and to communicate with the vehicles. The goal of this paper is to present the possibility of using such units in urban road infrastructure and to present an approach to traffic nodes management for saturated or over-saturated traffic states.

As the urban traffic volumes reach their daily peak values, the surface traffic in modern cities suffers from frequent breakdowns and traffic jams. One of possibilities that could mitigate the problem is the deployment of smarter automatic systems of urban traffic control. Our paper demonstrates a development version of such a system. The system is based on adaptive feedback control approach. It makes use of filtering techniques to account for measurement imperfections and implements the rolling horizon method for optimal signal control. We compare the performance of the proposed system with two typical control approaches - pre-timed (or fixed) control, and traffic actuated (or dynamic) control. Different scenarios will be compared, including rapid changes in traffic volumes and reactions to incidents. The comparison is carried out using our demonstrator tool, based on TSS Aimsun micro-simulator. In order to keep the calibrated simulation as close to reality as possible, in the comparison runs we use real dense input volume measurements and simulate also the behavior of intersection controllers.

Modern Intelligent Transport Systems (ITS) are now being widely deployed; in order to ensure that these deployments will bring maximum benefit to end users and other stakeholders, an ITS architecture, which defi nes how the deployed system would fi t into overall ITS structure, has to be defi ned. Help is available to achieve these goals from the European ITS Framework (FRAME) Architecture, now being upgraded by the European project E-FRAME. Within this project also the importance of mutual influence between standards and architecture is judged.

The goal of traffic control is to influence the traffic in the way it becomes more effective and safe. At present traffic control is working with the traffic flow considering it a quantity that is possible to regulate and control. The fact that each vehicle represents an independent intelligence is usually not taken into account. In fact each vehicle's driver decides in dependence on many different factors - from his knowledge and information he possesses to his actual state of mind. When all individual reactions of drivers are combined, self-organizing processes may arise and these self-organizing tendencies may sometimes contribute to the improvement of traffic situation but sometimes they may counterwork and cause more traffic problems.

Celem sterowania ruchem jest wpływ na ruch w taki sposób, aby stał się on bardziej efektywny i bezpieczny. Obecnie sterowanie ruchem działa na strumień ruchu, uważając go za ilość, którą można regulować i kontrolować. Fakt, że każdy pojazd przedstawia niezależną inteligencję zazwyczaj nie jest brany pod uwagę. W zasadzie kierowca każdego pojazdu decyduje - w zależności od wielu różnych czynników - od własnej wiedzy i informacji, jakie posiada, po aktualny stan umysłu. Kiedy połączone zostaną wszystkie indywidualne reakcje kierowców, mogą wystąpić procesy samoorganizujące się i te tendencje do samoorganizacji mogą czasem pomóc w usprawnieniu sytuacji ruchowej, aczkolwiek czasem mogą działać wręcz odwrotnie i powodować dalsze problemy z ruchem.
