Toward Accurate and Valid Estimates of Greenhouse Gas Reductions from Bikeway Projects

This research explores the determinants of greenhouse gas (GHG) reductions from bicycle projects in order to set an agenda for future data collection and assist the California Department of Transportation in estimating GHG reductions. The research team will augment existing before-and-after bicycle count data with original intercept survey data. The research team will also estimate the change in GHG to discern the key factors that determine the magnitude and direction of the change, considering bikeway type, locational context, population and employment variables, and local travel behavior, among other variables. The final research product will be a methodology to estimate GHG reductions from bikeway projects.
