Methods VMT FORECASTING VMT = Volume x Distance or Trips x Trip Length www.fehrandpeers innovation
Methods What VMT CountS? Project Generated VMT vs. the Project’s Effect on VMT
Methods What VMT Counts?
Tools Estimates vs Forecasts Boundary VMT Method • Citrus Heights = 1,000,110 daily VMT www.fehrandpeers innovation
Tools Network Models Origin-Destination (OD) VMT Method www.fehrandpeers • Citrus Heights = 1,397,340daily VMT innovation
Tools Land Use Projects www.fehrandpeers innovation
Tools TRIP GENERATION www.fehrandpeers innovation
Tools TRIP GENERATION www.fehrandpeers innovation
Tools Trip Lengths
Tools built environment Sensitivity Distanceto Transit DevelopmentScale Density Demographics Design Destinations Diversity www.fehrandpeers innovation 7Ds - That influence Trip Generation (and VMT)
Thresholds ? KEY QUESTIONS • What change in VMT constitutes a significant impact? • Does project type matter? • Is project effect on VMT more relevant than project generated VMT? • Should VMT changes be analyzed under project and cumulative conditions? • What role does regional transportation planning play in VMT impact analysis? www.fehrandpeers
Thresholds evidence Project’s VMT or Project’s Effect on VMT • Laws • Regulations • Plan Goals www.fehrandpeers innovation
Thresholds VMT Screening RTP/SCS Consistency • Land use projects • Transportation projects (induced travel) www.fehrandpeers innovation
Thresholds VMT Screening • Screening Maps for Low VMT areas www.fehrandpeers innovation
Thresholds ? Current VMT www.fehrandpeers
Methods ? Land Use vs Trip/Tour Type www.fehrandpeers
