Building Planner Commitment: Are Oregon’s SB 1059 & California’s SB 375 Models for Climate-Change Mitigation?

Keith Bartholomew Reid Ewing
Oregon’s Sustainable Transportation Initiative (SB 1059) and California’s Sustainable Communities Act (SB 375) have made them the first states in the nation to try and reduce greenhouse gas (GHG) emissions using the transportation-planning process. Evaluating how these pioneering laws have changed local planning processes – as well as plans themselves – in each state provides insight into the laws’ effectiveness at changing development patterns in a way that reduces GHG emissions, without… Read More

Biking and Walking Quality Counts: Using “BikePed Portal” Counts to Develop Data Quality Checks

Nathan McNeil Kristin Tufte
Cycling and walking are sustainable modes of transportation which improve community livability, but these modes have not been studied with the quantitative rigor applied to motor vehicle travel. This research aims to change that by improving bicycle and pedestrian traffic monitoring data quality. This research will address the question, how can erroneous data best be identified through automated processes? The research team will answer this question by analyzing continuous bicycle and… Read More
