Automatic Passenger Counting
Efficient Collection of Ridership and On-Time Performance Data
Vehicle System
The APC System in the vehicle consists of the following modules:
• On-Board Computer COPILOTsmart including the WLAN unit
• GPS-Receiver
• Passenger counting sensors
• Passenger counting analyzer
The core unit of the vehicle system is INIT’s on-board computer, COPILOTsmart which stores
the APC data received from the analyzer unit(s), and transmits the data via Data Transmission
Unit to the post-processing system for evaluation and analysis.
2.1 Vehicle Counting Components
The sensors are installed above the door. The typical counting components for a LRV are shown
in the picture below. Four analyzers are needed per train, (one analyzer for two doors), 16 sensors
per train, (2 sensors per door), 1 COPILOTsmart per train. A bus will need at least two sensors,
one analyzer.
