Letting drivers choose how fast to drive: Analyzing the strengths and weaknesses of the 85th percentile rule
This research synthesis will review the history and evolution of the 85th percentile rule in traffic engineering practice, and critically analyze and summarize research to date on its effects. The resulting report, policy brief, and Infographic will provide a complete and succinct summary of how the rule evolved into practice, and what researchers have found…

From traffic impact analysis to accessibility impact analysis: Developing and testing a post-LOS, post-VMT development impact analysis tool
This translational research will build on a series of recent research projects and papers by the author and his current and former students on shifting from a mobility to an access focus in evaluating the causes and (especially) consequences of traffic congestion on the functioning of cities and their economic agglomerations (Mondschein and Taylor 2017;…

Roads, Density and Prices: A Translational Project
I propose translational research to clarify the relationships between congestion, road pricing, density and transit ridership. My research work over the past five years has addressed all of these issues, but the work exists mostly in the atomized form required of academic journals. Now, however, these concerns are converging in California, and policymakers are asking…

Fast, Furious & Fatal: An Assessment of Speed-Setting Methodology in California
This study will explore the research and evidence to support using the 85th percentile rule for setting the speed limit, particularly in urban areas. The study will review the evolution of the rule and its application in cities primarily using interviews conducted with engineers, law enforcement officers, local political leadership, and legislators in the City…
