Traffic count
A traffic count is a count of vehicular or pedestrian
Counting methods
To permanently or temporarily monitor the usage of a road, an electronic traffic counter can be installed or placed to measure road usage continuously or for a short period of time. Most modern equipment called ATR's (Automatic Traffic Recorders) store count and/or classification data recorded in memory in a timestamp or interval fashion that can be downloaded and viewed in software or via a count display on some equipment. In some instances people either draw up a table and/or use a tally to keep a record of vehicles which pass manually as an alternative to ATR's.
Traffic counter devices
A traffic counter is a device, often electronic in nature, used to count, classify, and/or measure the speed of vehicular
Recently, off-road technologies have been developed. These devices generally use some sort of transmitted energy such as radar waves or infrared beams to detect vehicles passing over the roadway. These methods are generally employed where vehicle speeds and volume are required without classification which require on-road sensors.[4][5] Other off-road technologies are video image detection systems. A portable digital camera unit can be mounted to a pole and computer vision software is used to analyze traffic pattern including traffic counts.[6][7]
Traffic count software can now also classify vehicles - recording numbers of cars, trucks, bikes etc as well as total numbers - as well as registering how many travelled that way before. [8]
Bicycle and pedestrian traffic counting devices

In 2004, the American private-sector firm Alta Planning and Design, in partnership with the Institute of Transportation Engineers (ITE) initiated the National Bicycle and Pedestrian Documentation Program (NBPD) as an effort to promote greater data collection for non-motorized transportation modes, establish a consistent model for data collection, and address the lack of data access and shared research.[9][10][11]
In 2013, the US Department of Transportation, Federal Highway Administration (FHWA) expanded and created a chapter on non-motorized counting for the Traffic Monitoring Guide (TMG) designed to guide planning agencies in the collection of their data.[9]
