People and Nature. Returning back to the ecological transportation. Transportation in cities with its related environmental and social concerns is a topic of the utmost priority for urban authorities and central government organisations around the world. Urban Transport systems require considerable studies to safeguard their operational use, maintenance and safety. The continuing requirement 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 demonstrates the steady growth and research into urban transport systems. The variety of topics covered by the conference are of primary importance for analysing the complex interaction of the urban transport environment and for establishing action strategies for transport and traffic problems.
