Bicycle counter

Bicycle counters are devices that conduct a traffic count of passing bicycles. Some counters can also detect the speed, direction, and type of bicycles. Most bicycle counters consist of a discrete sensor and a computing device to record and store the data although some also have a public-facing display to show the total number of cyclists of the current day and year. Such systems (with the prominent display) are sometimes referred to as bicycle barometers. There are bicycle counters in hundreds of cities around the world. The first bicycle barometer was installed in Odense, Denmark, in 2002 though cities had been conducting systematic counts of cyclists at least as early as 1994.
