caption_attribution_description: English: This bicycle &amp; pedestrian counter (manufactured by Eco-Counter) is capable of collecting bi-directional bicycle &amp; pedestrian traffic (i.e. the direction of travel of each pedestrian, bicycle, et al. is logged). The device's sensor detects infrared radiation emitted by each person who passes by it. The sensor's narrow profile further enables it to count two or more people following closely to one another. The device will function at temperatures between -40 deg. F up to 122 deg.F. This device cannot distinguish between bicycles or pedestrians. A common factor reducing the level of observation (i.e. under-counting) of this data is lack of the pyroelectric sensor's ability to detect adjacent-travelling bicyclists or pedestrians (See page 10 in the paper: "Effectiveness of a Commercially Available Automated Pedestrian Counting Device in Urban Environments: Comparison with Manual Counts" ~ 22 Jul 2007).
context_page_description: Bicycle counters are electronic devices that detect the number of bicycles at a location for a certain period of time. They are sometimes referred to as bicycle barometers, but the term is misleading because it indicates the measurement of pressure. Most counting stations only consist of a sensor and some use a display to show the total number of cyclists of the day and the current year. There are counting stations all over the world in over hundreds of cities, for example in Manchester, Zagreb, or in Portland. The first bicycle counting station was installed in Odense, Denmark, in 2002.
context_section_description: Different techniques are used for detection of bicycles, such as built in induction loops, pneumatic hoses, infrared sensing or cameras. Different setups provide different advantages such as more precise counting, battery life, reduced costs or differentiation between different road users such as cyclists, pedestrians or cars. Pneumatic tube setups are said to have an accuracy of 80%, manufacturers state a 90% accuracy for induction loops
