Bicycle counters are electronic devices that detect the number of bicycles passing by a location for a certain period of time.[1][2] Some advanced counters can also detect the speed, direction, and type of bicycles.[3] These systems are sometimes referred to as bicycle barometers,[4] but the term is misleading because it indicates the measurement of pressure. Most counting stations only consist of sensors, the internal computing device, although some use a display to show the total number of cyclists of the day and the current year.[1] There are counting stations all over the world in over hundreds of cities,[5] for example in Manchester, Zagreb, or Portland. The first bicycle counting station was installed in Odense, Denmark, in 2002.[1][4]
