Book excerpt: A continuous requirement for better urban transport systems and the need for a healthier environment has resulted in an increasing demand for new solutions. Innovative systems, new approaches and original ideas need to be thoroughly tested and critically evaluated before they can be implemented in practice. Moreover, there is a growing need for integration with telecommunications systems and IT applications in order to improve safety, security and efficiency. This volume also addresses the need to solve important pollution problems associated with urban transport in order to achieve a healthier environment. The variety of topics covered by the included research works, which were presented at the 26th International Conference on Urban Transport and the Environment, reflect the complex interaction of urban transport systems with their environment and the need to establish integrated strategies. The goal is to arrive at optimal socio-economic solutions while reducing the negative environmental impacts of current transportation systems.
