In 2008 humanity has reached a turning point in its history. For the first time ever, more than half of the world population is living in urban areas. No city today can function efficiently without public transport. The question for planners has therefore shifted from "should we invest in public transport?" to "which modes should we choose?".All urban decision-makers face the issue of providing public transport to meet citizen's needs efficiently. The 58th UITP Congress will: - Present the most up-to-date options with their advantages and drawbacks;- Review all parameters to take into account: planning, costs, capacity, urban integration, operation, management;- Consider the impact of geography and culture on public transport;- Provide a broad view of the issues and a framework, enabling delegates to take the best possible decisions for the short, medium and long term.This will allow delegates to take a complete 'tool kit' home.
