Research Highlights
Online Non-motorized Traffic Count Archive
Krista Nordback
Kristin Tufte
Robust bicycle and pedestrian data on a national scale would serve numerous purposes. Access to a centralized nonmotorized traffic count archive can open the door for innovation through research, design and planning; provide safety researchers with a measure of exposure; provide fundamental performance metrics for planning and funding decisions; and allow policymakers and transportation professionals to better support the public’s desire for livable communities. Numerous jurisdictions have in...
