Each NPS unit is required to complete a Comprehensive (or General) Management Plan (CMP) that defines the park's basic approaches to natural and cultural resource protection, visitor experience, facilities, and partnerships for the next 15 - 20 years. The alternative transportation needs assessment is a component of the CMP. This study, developed as a first phase of alternative transportation systems (ATS) support for CAJO, focuses on two primary components: an ATS inventory and a regional ATS analysis.
