Vidar Axle Counting Camera

An axle counting and vehicle classification camera system captures images of passing vehicles from a low angle, counting individual axles and identifying vehicle type for toll collection, weigh station operations, and traffic data collection. The camera mounts at road level or on a low pole, typically 30 to 60cm above the pavement, angled to capture a clear view of wheels and axles as a vehicle passes over the detection zone. Frame rates on most systems reach 60 to 120 frames per second, fast enough to capture individual axles clearly even on vehicles moving at highway speed.

Detection accuracy for axle counting typically exceeds 98% under normal conditions, with the system distinguishing between single axles, tandem axles, and closely spaced axle groups common on trucks and trailers. Vehicle classification software processes the axle count alongside vehicle length and height data from paired sensors, sorting traffic into standard classification categories used for toll pricing tiers or traffic volume reporting. Housing is usually a rugged, weatherproof enclosure rated IP66 or higher, protecting the camera from dust, rain, and vibration from nearby traffic over years of continuous roadside operation.

Illumination for nighttime operation comes from infrared LED arrays synced to the camera’s shutter speed, capturing clear axle images without needing visible flash that could distract drivers. Data output connects to a toll management or traffic monitoring system through standard network protocols, sending classification results in real time for automated toll calculation or traffic report generation. Some systems add a backup image storage function, keeping a visual record for dispute resolution on toll charges.

Toll road operators use axle counting cameras to calculate accurate toll rates based on vehicle class rather than a flat fee for all traffic. Highway authorities use them for traffic volume studies and vehicle classification data collection. Weigh station operators also rely on axle detection to flag vehicles for weight compliance checks.

Tactical Supply Pakistan supplies axle counting and vehicle classification camera systems to toll road operators, highway authorities, and weigh station operators across Pakistan. Frame rate and classification accuracy are matched to each site’s traffic volume and speed conditions.
