PERIOD
refers to the data format: hourly totals, daily totals, or timestamps (all are records)
▪
14 000 is the maximum number of records (lines of data)
▪
Totals are much more memory efficient and download much faster than timestamps
001
= Hourly totals (default; recommended); stores 19 months of data (448 million counts max.)
024
= Daily totals (rarely used); whole days only; counting starts and stops at mid-night
000
= Timestamps (seldom used); each event creates a timestamp (14 000 counts max.)

A count occurs in the detection zone. The

The other way to increase sensitivity is simply to move the counter closer to where bikes pass

Counters yield estimates. They are rarely 100% accurate. This applies to all types and brands. Counter
calibration is recommended when higher accuracy is desired. Calibration involves comparing counter
totals with those observed by a person, ideally over several hours. It is also a good opportunity to collect
additional data (youth vs. adult, etc.). Fo
