Data - Driven Traffic Management with Road Weather Stations

Road Weather Stations provide crucial basic data. They accurately monitor the temperature. When the temperature drops below 0°C, the road may freeze. This data enables the traffic management department to issue early warnings and take timely measures such as spreading salt to melt snow or closing the road to prevent vehicles from skidding out of control. Humidity monitoring is also of great importance. High humidity can easily trigger fog, reducing visibility. The weather station monitors humidity changes in real-time. By combining this with other elements, it can predict the formation of fog, allowing the management department to issue early warnings and remind drivers to pay attention to safety. Strong winds have a significant impact on large vehicles. At windy sections, the monitored strong wind information can help the traffic department implement control measures to prevent vehicles from being endangered by strong winds.

Precipitation monitoring is also an important task of the weather station. Light rain makes the road slippery, and heavy rain may trigger disasters such as floods and landslides. The weather station accurately monitors the precipitation. Near mountain roads, strong precipitation warnings enable the traffic department to make advance preparations, such as clearing drainage facilities and strengthening inspections. Visibility monitoring is directly related to driving safety. Low visibility is an important cause of accidents. The visibility monitoring equipment of the weather station can measure in real-time, and the data is quickly transmitted to the traffic control center, so that corresponding measures can be taken.

The data of the weather station is shared through the network. Multiple weather stations form a monitoring network. The data is summarized to the meteorological center or the platform of the traffic management department, enabling a comprehensive understanding of the regional meteorological conditions and advance planning of response measures. The traffic meteorological warning system established based on this data can issue different levels of warnings by comprehensively considering the characteristics of the road section and meteorological conditions. These warnings are issued through various channels, allowing drivers to be informed in advance and plan their trips reasonably.

The data of the weather station can also work in coordination with traffic facilities. For example, it can be integrated with intelligent traffic lights to adjust the signal duration according to the weather and optimize the traffic flow. At bridges prone to icing, the automatic snow - melting device is activated when the temperature approaches the freezing point to ensure the safe passage of the bridge.
