Traffic counters are devices used to measure the number of vehicles or pedestrians passing a specific point over a set period. They can be found on roads, sidewalks, and in public transport areas. These counters help city planners and transportation agencies understand traffic patterns and make informed decisions about infrastructure improvements. There are various types of traffic counters, including inductive loop sensors, infrared sensors, and video cameras. Each type has its own method of counting, such as detecting metal in vehicles or using motion detection technology. The data collected can assist in reducing congestion and enhancing safety on the roads.
