8.2.4 Develop Alternatives
Prior to developing alternatives, the project team defines the scope and study area, determines the purpose and need, and sets project goals and objectives (see
Chapter 1
for guidance). Developing alternatives demands understanding the issues. Coordination with project stakeholders is necessary to establish that an appropriate range of alternatives is considered. The number of alternatives acknowledged varies by project scope and level of detail; three to five alternatives are generally evaluated at each “tier.” Potential solutions to be considered include:- Transportation System Management and Operations (TSMO) strategies;
- Transportation demand management improvements;
- Transportation system management improvements;
- Access control and local circulation changes;
- Multimodal and intermodal improvements;
- Safety solutions;
- Segment improvements;
- System improvements;
- Intersection improvements; and
- Interchanges
Consider developing alternatives with enough detail to adequately evaluate benefits and costs.
