The system presents zone conditions and trends.

Operators responsible for road tunnels, underground transport corridors, ventilation zones, portals, gas and visibility monitors, airflow sensors and control rooms cannot continuously inspect every operating condition or developing fault. Periodic checks leave gaps between readings, while isolated local indicators provide limited history and context. A late response can cause downtime, safety exposure, equipment damage, or incomplete compliance evidence. Teams need timely measurements, clear exceptions, and a defined operating response.
Road Tunnel Air Quality Visibility and Ventilation Monitoring combines connected field data with application software. Distributed tunnel instruments measure CO, NO, NO2, particulate matter, visibility, cold smoke, luminance, illuminance and air movement by configuration. The system presents zone conditions and trends, detects unsafe visibility or pollutant levels and supplies inputs for ventilation decisions. Operators vary ventilation, issue safety responses, investigate incidents, maintain sensors and document tunnel air-quality performance.
Teams configure the monitored assets, users, and operating rules. Distributed tunnel instruments measure CO, NO, NO2, particulate matter, visibility, cold smoke, luminance, illuminance and air movement by configuration. CODEL instruments exchange measurements with local control and reporting systems and optional CODEL Cloud; no single public transport applies universally. The system presents zone conditions and trends, detects unsafe visibility or pollutant levels and supplies inputs for ventilation decisions. Operators vary ventilation, issue safety responses, investigate incidents, maintain sensors and document tunnel air-quality performance.
