    Nonmotorized Transportation Pilot Program Evaluation Study, Phase 2
    (Center for Transportation Studies, University of Minnesota, 2011-05) Götschi, Thomas; Krizek, Kevin J.; McGinnis, Laurie; Lucke, Jan; Barbeau, Joe
    The Nonmotorized Transportation Pilot Program (NTPP) is a congressionally mandated program (SAFETEA-LU Section 1807) that, since 2006, has provided roughly $25 million each to four communities—Columbia, Missouri; Marin County, California; Minneapolis area, Minnesota; Sheboygan County, Wisconsin—to spur levels of walking and cycling via a variety of planning measures. The University of Minnesota Center for Transportation Studies is leading the community-wide population surveys for the Nonmotorized Transportation Pilot Program (NTPP), specifically in phase 2, to measure changes in levels of walking and bicycling as a result of the enhanced conditions for walking and bicycling. To evaluate impacts of the program, two community-wide surveys were conducted before (phase 1: 2006) and after (phase 2: 2010) the pilot program. This report describes the evaluation efforts based on community-wide population surveys. In contrast to project-specific evaluations, community-wide surveys serve the purpose of representatively assessing community-wide levels of nonmotorized travel behavior, which serve as the foundation for subsequent benefit calculations. The survey in phase 1 consisted of a short mail-out questionnaire and a computer assisted telephone interview (CATI) among respondents to the short questionnaire. In phase 2 the short questionnaire was integrated in the CATI. The final sample in phase 1 consisted of 1279 complete records and in phase 2 of 1807 complete records. Statistical analysis focused on evaluating differences between phase 1 and phase 2 in the core variables on nonmotorized travel behavior. The detailed analysis did not reveal any consistent or statistically significant differences between phases 1 and 2. It is important to point out that the inability to detect significant patterns of change is not synonymous to no change occurring. The report discusses some of the factors that make this type of research challenging.

    Reducing Greenhouse Gas Emissions From Transportation Sources in Minnesota
    (University of Minnesota Center for Transportation Studies, 2008-06) Boies, Adam; Kittelson, David B.; Watts, Winthrop J.; Lucke, Jan; McGinnis, Laurie; Marshall, Julian; Patterson, Tyler; Nussbaum, Peter; Wilson, Elizabeth
    The 2007 Minnesota Next Generation Energy Act established goals for reducing statewide greenhouse gas (GHG) emissions by 15% by 2015, 30% by 2025, and 80% by 2050, relative to 2005 levels. This report investigates strategies for meeting those reductions in Minnesota?s transportation sector, which produces approximately 24% of total state GHG emissions. The study focuses on three types of emission-reduction strategies: those that improve vehicle fuel economy, those that reduce the number of vehicle-miles traveled, and others that decrease the carbon content of fuel. The researchers used a quantitative model to test the effectiveness of specific strategies for GHG emission reduction from transportation in Minnesota. Modeled scenario outcomes depend strongly on input assumptions, and lead us to the following three main conclusions. 1. Meeting state goals will require all three types of policies. For example, Minnesota could adopt a GHG emissions standard, a low-carbon fuel standard, and comprehensive transit and Smart Growth policies. 2. Technologies are available today to substantially improve fuel economy and vehicle GHG emissions. Requiring these technologies could save Minnesota consumers money and better insulate them from oil price volatility. 3. Changes in vehicle-miles traveled (VMT) have a strong impact on whether the goals can be met, and increases in VMT can offset GHG reductions. Overall, the research indicates that the goals can be met, but achieving them requires consistent and concerted action beginning immediately.

    A Smaller Carbon Footprint: Research Suggests Combining Strategies to Meet Legislative Goals in the Transportation Sector
    (University of Minnesota Center for Transportation Studies, 2008-06) Boies, Adam; Kittelson, David B.; Watts, Winthrop J.; Lucke, Jan; McGinnis, Laurie; Marshall, Julian; Nussbaum, Peter; Wilson, Elizabeth
    The 2007 Minnesota Next Generation Energy Act established goals for reducing statewide greenhouse gas (GHG) emissions by 15% by 2015, 30% by 2025, and 80% by 2050, relative to 2005 levels. This document summarizes a longer report which investigates strategies for meeting those reductions in Minnesota's transportation sector, which produces approximately 24% of total state GHG emissions.
