Applying Correction Factors
Let’s say 1,000 bicyclists cross the tubes 4 feet from the counter.

Applying Correction Factors
At this distance, the counter has an average accuracy of 94.68%, so we can expect 947 bicyclists will be counted.

Applying Correction Factors
Using the correction factor to correct for the known undercount, we can calculate that 1,000 bicyclists crossed the tubes

Confidence Intervals & Margins of Error
With a confidence interval of 2.68%, the margin of error for this count is ± 27 bicyclists
![Page 49: International Conference on Bicycle Urbanism-- Bike Counts](https://reader033.vdocuments.us/reader033/viewer/2022052906/558cfdafd8b42a644b8b45d4/html5/thumbnails/49.jpg)

Since the margins of error are larger at greater distances, using two counters will minimize the margin of error.

What’s possible now?
• Calculating Bicycle Miles Traveled (BMT) on county roads.
• Tracking long term trends of bicycling rates.
