Understanding how much biking and walking is occurring and where it is occurring can be important for understanding demand for biking and walking and safety. The most common types of data collection reported were mobile counters, mobile app data, and permanent counters. Thirty-three states reported using at least one type of bicycle or pedestrian traffic monitoring method.
Data is from 2021 Bicycle Friendly State survey response to the question, "Please indicate methodologies used for counting people who bike and walk that your state DOT has used or funded in the past 18 months."
