The in-tunnel counting system will track and count people to optimize their safety by quickly alerting emergency services in the event of a problem. With this solution it is possible to define danger zones and restrict access to certain people to ensure the smooth running of work or maintenance on site. Alerts can also be set up and a button can be activated at the touch of a button in the event of a problem. The technical solution of tunnel metering that we have implemented is applicable to all types of tunnels, regardless of their depth, allowing constant monitoring of the progress of the work.  It is also possible to use this system to count and geolocate the equipment in the tunnel.
