Transportation in cities, with 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 safety crises, which take place regularly, and even the best-planned urban transport systems require considerable studies to keep them operational, well-maintained, safe and secure.

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 the Fourteenth International Conference on Urban Transport and the Environment in the 21st Century , 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 analyzing the complex inter-relation of the urban transport environment and for establishing action strategies for transport and traffic problems.

This volume presents papers under the following topics: Transport planning and management; Public transport systems; Intermodal transport systems; Transport sustainability; Environmental and ecological considerations; Land use and transport integration; Transport technology; Intelligent transport systems; Road pricing; Transport modelling and simulation; Safety issues; Safety of users in road evacuation.
