The process of achieving more sustainable urban transportation systems designed with the principle of accessibility at their core is dependent on the participation of all stakeholders in cities, the authorities, the private sector and the citizens, along the lines of principles of democracy. A successful process will depend on effective governance of land use and transportation, where new housing and commercial planning will entail simultaneous transportation systems design, careful neighborhood design, strategic infrastructure investments, and fair, efficient and stable funding. The accessibility, in turn, is influenced by the availability of an efficient and effective transport system.
