An axle counter in the context of road traffic systems is a sensor device used to monitor vehicle traffic on roads and highways. Axle counters detect the presence of vehicles based on the number of axles that pass over a specific point on the road. Each time a vehicle passes, the axle counter registers the axles and uses this data to calculate traffic flow, count vehicles, and classify them based on the number of axles.
Axle counters are often employed at toll booths, intersections, weigh stations, and other locations where traffic needs to be monitored or controlled. They help gather valuable traffic data for road traffic authorities, optimize traffic control and assess road usage, contributing to more efficient and safer transportation systems.
