A significant proportion of the world's population live in metropolitan areas and the number is growing quickly. The success of the city has brought with it a series of needs, issues, problems and objectives that today's transport community must address if they are to be successfully resolved. Great progress has been made and the best is yet to come. Advanced technologies hold the promise of more intelligent cities, adapting to the needs of city dwellers. Smart telecommunications, sensors and information technology-based services can make the intelligent city of tomorrow an even better place in which to live and work. From a transport perspective these can significantly enhance service delivery, with minimum undesirable side-effects, if applied in a thoughtful and coherent manner. The intent of this paper is to explain the needs, issues, problems and objectives that advanced transport technologies might address, to provide a simple overview of technology applications and to describe a suggested approach for harnessing the power and benefits of advanced technology and conventional approaches with respect to metropolitan transport management. Lessons and approaches from the wider world of business and commerce are incorporated in the proposed approach, taking advantage of previous experience with similar applications.
