The main goal of PROPOLIS is to research, develop and test integrated land use and transport policies, planning tools and comprehensive assessment methodologies in order to define sustainable long-term urban strategies and to demonstrate their effects in European cities. The more detailed goals are described as follows:

1. To develop further theory of urban transport and land use systems;
2. To develop the planning and assessment methodologies;
3. To execute a policy testing process in 7 European urban regions using the knowledge already gained from the tests made in the case cities and executing a systematic process of policy testing;
4. To analyse the test results in order to define general urban strategies, to demonstrate their effects aiming at generalised conclusions (not dependending on the cities nor the models used);
5. To identify policy packages useful to reduce urban pollution and congestion and, at the same time, ensuring accessibility and mobility without compromising economic efficiency and social sustainability;
6. To establish close contacts with the policy/decision makers and users of the system, involving them in some phases/tasks of the project;
7. To adopt an effective dissemination and exploitation programme dealing with sustainable urban development during and after the project.
