Base your cycling policy decisions on data.

The TMA-3B3 combines radar and lidar to accurately count bicycles and measure their speed on bike paths. Its installation is simple, fast and safe.

It is available in three different housings:

– The TOTEM contains the sensor, the battery, the modem and the solar panel in an all-in-one elegant coated stainless steel casing, making it easy to install, robust and fully autonomous;

– The standard housing, for mobile applications, with a vandal resistant casing

– The compact housing, for mobile applications, with a reduced size casing

Operation and strengths

Installed on a mast, the TMA-3B3 combines two technologies to provide optimal counting accuracy on the bike path.  It is indeed able to count the number of cyclists in a group and to measure their individual speed.

  • 97 % accuracy at peak hours (compared to manual counting)
  • Non-intrusive
  • Autonomous and mobile (can be powered by solar energy)
  • Consistent performance day and night
