Transportation Planning Process

A transport planning process is the process of defining future policies, objectives, investments, action plans and spatial planning projects to meet future transportation-related needs. As is being done today, it is a collaborative process that incorporates the views of a wide range of stakeholders including various central and local government agencies, state-owned enterprises and the private sector. Transport planners, planning organizations or federal agencies use a multidisciplinary approach to analyze a variety of alternatives and impact on the transportation system to contribute to profitable outcomes.
