“Furthermore, increased efforts should also be directed at increasing vehicle occupancy, which has dropped by 30% from 1960. That drop, by itself, increased the energy intensity of driving per occupant by about 30%.” Sivek and Schoettle, “Eco-Driving: Strategic, Tactical and Operational Decisions of the Driver that Improve Vehicle Fuel Economy,” UMTRI, University of Michigan, Aug. 2011.

“Driving and the Built Environment”(TRB, Sept 2009) • More compact development patterns are likely to reduce VMT. 2. The most reliable studies estimate that doubling residential density across a metropolitan area might lower household VMT by about 5 to 12 percent, and perhaps by as much as 25 percent, if coupled with higher employment concentrations, significant public transit improvements, mixed uses, and other supportive demand management measures.
3. More compact, mixed-use development can produce reductions in energy consumption and CO2 emissions both directly and indirectly. 4. Significant increases in more compact, mixed-use development result in only modest short-term reductions in energy consumption and CO2 emissions, but these reductions will grow over time. • Bottom Line: Reduction in VMT, Energy Use, and CO2 emissions from more compact, mixed-use development in the range of <1 % to 11 % by 2050. • Committee disagreed about plausibility of extent of compact development and policies needed to achieve high end estimates.
Promoting more compact, mixed use development on a large scale will require overcoming numerous obstacles. 6. Changes in development patterns entail other benefits and costs that have not been quantified in this study.
“Moving Cooler” (ULI/CS, 2009) • Evaluated non-technology transportation strategies for (a) GHG reductions and (b) cost-effectiveness in reducing GHG • Analyzed 46 individual transportation strategies and 6 “bundles” • The 6 “bundles” of strategies: • Near Term/Early Results • Long Term/Maximum Results • Land Use/Transit/Non-motorized • System and Driver Efficiency • Facility Pricing • Low Cost • Did not analyze technology/fuel strategies (instead, technology is part of the baseline)
Individual strategies achieve GHG reductions ranging from <0.5% to 4.0% cumulatively 2010-2050, compared to on-road baseline GHG • 15,186 mmt - carbon pricing equivalent to $2.71/gallon • 3,361 mmt – VMT fees equivalent to $2.53/gallon • 2,428 mmt – speed limit reductions/enforcement • 2,233 mmt – PAYD auto insurance (100%) • 1,815 mmt – eco-driving by 20% of drivers • 1,445 mmt – at least 90% of new urban development is compact, with high quality transit • 1,241 mmt – congestion pricing fully implemented in 120 metro areas at 65 cents/mile • 575 mmt - $1.2 trillion transit expansion • 352 mmt – combination of 10 freight strategies
SANDAG • Promote transit-oriented design (TOD) by increasing housing and job density near transit nodes. • Promote mixed use development. • Increase the connectivity of new developments, using techniques such as reducing the number of cul-de-sacs and increasing the number of through streets. • Integrate safe bikeways and pedestrian paths into the transportation mix and provide bicycle parking and other facilities to encourage bicycling.
Summary • Transportation sector an important source of energy savings • Vehicle/fuel strategies most effective • Pricing, not surprisingly, the most effective of behavioral strategies • Systems operations…as a package • Transit….it all depends • Land use….it all depends
