Transportation in cities, with its related environmental and social concerns continues to be a topic of the utmost priority for urban authorities and central governments around the world. Frequently, the concern is not orderly but driven by the safety crises which take place regularly and even the best planned urban transport systems require considerable studies to safeguard their safety, maintenance and operational use.

On a broader front, the continuing need for better urban transport systems in general and the need for a healthier environment has led to an increased level of research around the world. This is reflected in the proceedings of this well-established meeting, which stresses the continuous steady growth and research into the urban transport systems control aspects, information and simulation systems. All these topics continue to be of importance for analysing the complex inter-relation of the urban transport environment and for establishing action strategies for transport and traffic problems.
