Visibility Monitoring Station: Ensuring Traffic Safety

Visibility, as an indicator reflecting atmospheric transparency, is an extremely important meteorological element for aviation, navigation, land transportation, and military activities. The application of automated measuring instruments for measuring atmospheric visibility, such as transmissive visibility meters and forward scattering visibility meters, continuously improves the automation level of meteorological observation, making visibility observation more objective, quantitative, and standardized, better meeting the needs of forecasting, service, and scientific research, and playing a huge role in meteorological disaster prevention and mitigation work.

Application case of visibility monitoring station:
In a provincial expressway network, in autumn and winter, heavy fog weather frequently occurs in this area. The meteorological department monitors the changes in visibility in real time through visibility monitoring stations distributed along the expressway. When it is monitored that the visibility of some sections is lower than the safety standard, the data is immediately transmitted to the traffic management department.

According to the visibility data provided by the meteorological department, the traffic management department quickly activates the emergency plan. Implement temporary closures on sections with extremely low visibility, set up warning signs at expressway entrances, and remind drivers to detour or wait for the fog to disperse.

Through channels such as traffic radio and expressway electronic display screens, road condition information and visibility conditions are promptly released to drivers to guide drivers to reasonably arrange travel routes.

This measure effectively avoids serious traffic accidents such as multiple vehicle rear-end collisions caused by heavy fog and ensures the traffic safety of expressways.
