The framework image illustrates the six key phases that agencies are likely to encounter when implementing the scenario planning process:
Each phase lists considerations and outputs to help guide agencies in managing and implementing a comprehensive scenario planning effort. The considerations and outputs identified under each phase are as follows:
Considerations: Process goals, objectives, budget, and stakeholder roles and responsibilities.
Output: Work plan.
Considerations: Transportation and land supply, suitability, and demand. State, regional, community, or study area trends.
Outputs: Transportation systems inventory, land suitability analysis, evaluation of historical trends.
Considerations: Key values and priorities for the state, community, region, or study area.
Outputs: Set of working principles that document broad state, community, region, or study area goals and preferences.
Considerations: Scenario types, analysis tools, travel demand model.
Outputs: Identification of appropriate scenario analysis tool or refinement of travel demand model; baseline and alternative scenarios.
Considerations: Indicators to help evaluate scenario performance.
Outputs: Refined or calibrated analysis tool(s) or model(s) if necessary; list of indicators to compare scenario outcomes; qualitative or quantitative assessment of scenario impacts.
Considerations: Stakeholder feedback on scenarios and the future blueprint; potential actions, investments, or policies to lead the state, community, region, or study area toward the comprehensive vision
Outputs: Comprehensive vision; action steps; performance measures to assess progress; plan for monitoring progress.
Lastly, the framework image indicates the phases that involve data collection (phases 1 and 2); identification, preparation, and refinement of analysis tools (phases 1 through 4); and stakeholder involvement (all phases).
