TNL-VIS: TNL-VIS: Visibility measuring device


TNL-Co-No: pollutant measuring device


TMS: Traffic management system

The TNL-VIS device measures the visibility conditions inside road-traffic tunnels. The device measures the attenuation of a laser beam due to aerial pollutants and fog. The output of the device can, for example, be used to control lighting. The device is highly reliable and accurate and is easy to install and support.

The TNL-Co-No device measures the exact concentration of specific aerial pollutants inside road-traffic tunnels. The device can be used in air-cleaning set-ups. The device measures exact concentration of No and Co elements in the air.

Software package with advanced traffic control algorithms and friendly user interface for real-time monitoring and optimized management of normal and of emergencies on large national highways.




Software package offering central Supervisory Control and Data Acquisition (SCADA) functionality tailored to the needs of large national highways. In more detail, central control and management of electromechanical equipment of open or closed space (tunnels) is possible, regarding these parameters and activities:
  • Road lighting.
  • Tunnel lighting
  • Tunnel Ventilation
  • Fire Detection
  • Traffic Control and Lighting
  • Closed Circuit TV and Emergency Telephones
  • Electric Power Distribution
  • Pumps
  • Auxiliary systems:
    • Detection of Meteorological Data
    • Light Intensity Measurements
    • Measurement of the Quality of the Air and of the Velocity of Air Inside Tunnels

A building and energy management system (BEMS) provided by Algosystems is a complete project with offering of state-of-the-art hardware and software with field installation and start-up services, with education and of course maintenance. Such an installation is designed by Algosystems to be extensible, with capacity to measure and control several parameters and/or other automation systems, and offers complete central reporting, printing and storing capacity of historical data, statistical data, alarms, etc.

Critical aspect of the success of the BEMS solution by Algosystems is its reasonable budget and Algosystems' capacity to complete such projects on time and budget.
