An Alternatives Analysis (AA) is a transportation planning process for evaluating all reasonable modal and multimodal alternatives and general alignment options for identified transportation needs in a corridor. An alternatives analysis is viewed as a good planning practice designed to assist communities with objectively selecting transit options that address a community's transportation needs. The Locally Preferred Alternative (LPA) that results from an AA moves onto the National Environmental Policy Act (NEPA) mandated environmental review process. During NEPA, the LPA's impacts on both the natural and human environments are assessed. A transit option must be approved through both the AA and NEPA processes before it can proceed to Preliminary Engineering phase.
