Automatic Passenger Counter.
98%+ Accuracy. Stop Transit Fare Leakage.
Overhead dual-lens 3D stereoscopic vision sensor tracking boarding and alighting flow in real time. Designed for public buses, intercity coaches, and BRT networks across Bangladesh.
Dual-Lens 3D AI Passenger Counter
Overhead door mounting (2.0m - 2.8m). Filters out luggage, backpacks, and lingering passengers without double-counting.
What is an Automatic Passenger Counting (APC) System?
An Automatic Passenger Counter (APC) is an intelligent computer vision device mounted directly above bus doors that uses dual-lens stereoscopic 3D depth perception to count the exact number of passengers boarding and alighting at each stop.
In Bangladesh's public transport sector, bus fleet operators (e.g. Lal Sobuj, Shohagh, Ena, and Dhaka city franchises) suffer massive ticket revenue leakage—frequently 15% to 25% of daily fares—due to conductors taking cash without issuing tickets or underreporting passenger counts. ADL Moto's APC system operates autonomously without relying on human honesty. It correlates passenger count deltas with GPS bus stops, cross-verifies against electronic ticketing machines (ETM), and gives fleet owners 100% financial revenue assurance.
Why 3D Stereoscopic Vision Outperforms Infrared Beams
Old infrared break-beam counters fail when passengers walk side-by-side or carry bags. ADL Moto uses binocular stereo vision.
True Height & Depth Mapping
Dual lenses generate a real-time 3D point cloud of the doorway. The AI calculates human head and shoulder heights (70cm - 210cm), instantly ignoring trolleys, backpacks, umbrellas, and floor shadows.
Simultaneous IN / OUT Tracking
Tracks multiple people passing through the door simultaneously in opposite directions. Accurately records boarding vs alighting even in crowded peak-hour rush conditions.
Doorway Lingering Filter
Conductors and passengers standing near the door without passing the threshold line are tracked continuously without triggering repetitive duplicate counts.
