Research Highlights

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 pedest... Read More

Washington State Pedestrian and Bicycle Miles Traveled Project

Krista Nordback
Estimates of vehicle miles traveled (VMT) drive policy and planning decisions for surface transportation. No similar metric is computed for cycling and walking. What approaches could be used to compute such a metric on the state level? This report discusses three such approaches, identifies the advantages and disadvantages of each, and applies them to Washington State. The first approach employs travel survey data. The second approach is sample-based using pedestrian and bicycle count data. T... Read More
