Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
1 Objective Start a national dialogue about the makeup of a suite of core environmental performance measures that help state DOTs understand and communicate the impacts of transportation on the environment and make more informed business decisions Five FOcUS AReAS ⢠Air quality ⢠Energy and climate ⢠Materials recycling ⢠Stormwater ⢠Wildlife and ecosystems PROOF OF cONcePt teStiNG (27 StAteS) CA, CO, DE, FL, GA, IL, IA, ME, MD, MN, MO, NE, NJ, NM, NC, ND, OH, OR, PA, SC, SD, TX, UT, VT, VA, WA, WY tHe ReSeARcH MetHOD Select environmental focus areas and identify universe of 2001 possible measures; Screen suggested measures, based on desired criteria; Validate suggested measures in proof of concept tests with 26 states; Create detailed methodology guidance for final measures SUGGeSteD AiR QUALitY MeASURe Change in statewide motor vehicle emissions for NOx, VOC, and PM2.5 Avg.
