addressing climate change adaptation in regional transportation plans

Addressing Climate Change Adaptation in Regional Transportation PlansA Guide for California MPOs and RTPAsteam intended to use redundancy (or the lack thereof) as another factor to adjustrelative criticality, but no systematic data suitable for GIS analysis was available.Subsequently, a GIS was employed to quantitatively allocate all network roadsinto tiers of criticality. This process is replicable using any attribute data that canbe allocated into a geospatial unit, and is explained in full in the technicalappendix. It is important to note that this approach was developed to provideagencies with a robust platform to support decision-making, but it is notintended to substitute for the judgment and discretion of agency officials orpublic stakeholders. It is recommended that a validation or “truth testing”process succeed the technical analysis to ensure that regional and local prioritiesare properly reflected.
