Scenario planning is a process that evaluates the effects of alternative policies, plans, and/or programs on the future of a community or region. This activity can provide information to decision-makers as they develop transportation plans. Scenarios may be used by stakeholders to explore and debate alternatives and trade-offs. By testing several scenarios against performance indicators, decision-makers can select a preferred scenario and identify an appropriate set of actions that will lead toward that vision.
