Onboard Counting Computer

GW-400 Communication Gateway

The GW-400 Communication Gateway is an onboard counting computer that works together with the DA- 400 sensor series to create a highly accurate and precise Automatic Passenger Counting (APC) system.

The ultra-compact GW-400 is fully autonomous or can be easily connected to other existing onboard computers and TCMS. Its built-in power supply can adapt to a wide range of voltages.

These counting computers are installed inside the vehicles. At each station, they receive the signals from the DA-400s, transform them into counting data, which are then stored in the GW-400s’ memory until they receive a download command.

The data is usually transferred, directly from the GW- 400 via a wireless module to the ground data analysis server. This saves on:

  • Cabling costs
  • Installation time


In brief, the GW-400 records the following data:

  • “In” and “Out” counts per sensor, per door at each stop
  • Time of arrival and departure at each stop
  • Stop location and distance (with GPS option)
  • Distance (if odometer signal available)
  • Time of passage in front at each station • without vehicle stop (virtual signpost)
  • Speed of door opening and closing
  • Detailed diagnostic information on sensors,
  • High sensitivity GPS, door signals, system integrity, etc.

Detailed diagnostic information is coupled with our diagnostic software package to allow an efficient fleet status analysis. Diagnostic information is recorded in the system and the GW-400 can send warning or error messages to onboard computers or to a central computer.
