Rain, fog, and other harsh weather conditions are major "adversaries" threatening traffic safety. Low visibility in particular severely impairs drivers' vision, highly increasing the risk of traffic accidents and causing casualties and property losses. The emergence of Atmospheric Visibility Sensors has enhanced the safety of expressways during rainy and foggy days.
These sensors are typically installed at key locations along roadways, such as bridges, curves, long downhill sections, and other accident-prone areas. Set up at regular intervals, they form a tight monitoring network to continuously measure visibility in the surrounding areas. Once rain or fog arrives and visibility drops, the monitors quickly respond, transmitting real-time data to the traffic management department's control center in minute-level or even second-level speed.
When visibility falls below the safety threshold, the system immediately activates the early warning mechanism. On one hand, variable message boards along the expressway release eye-catching warning information to passing drivers, notifying them of the visibility conditions ahead and reminding them to slow down and maintain safe following distances. On the other hand, traffic management departments scientifically formulate traffic control measures based on the data. If visibility is extremely low, speed limits, closures, or other measures may be taken for certain sections to ensure driving safety. When a sudden drop in visibility is detected, the system simultaneously triggers tunnel broadcast prompts and lane indicator light switching to guide drivers through safely.
Atmospheric Visibility Sensors can also integrate with intelligent street lighting systems to automatically increase streetlight brightness during low visibility, and cooperate with vehicle autonomous driving assistance systems to provide them with external environmental visibility information, aiding vehicles in making more reasonable driving decisions.
For example, Atmospheric Visibility Sensors act as the "see-through eyes" of expressways. In harsh weather like rain and fog, they provide data for traffic management and timely warnings for drivers, safeguarding expressway traffic safety and improving road traffic efficiency.
In areas with clean air, the visibility can reach as high as 70-100 kilometers, but air pollution and humidity often reduce it. In areas with haze, fog, smoke, or in the places where sandstorms or forest fires occur, low visibility is extremely dangerous for transportation. Many serious accidents on...
On the rooftops of distributed photovoltaic power stations and between small photovoltaic arrays, a compact and sophisticated monitoring device is often seen – this is the PV Weather Station. With its small size, flexible deployment, and precise monitoring capabilities, it provides reliable data fo...
Small automatic weather stations are an important part of the meteorological monitoring and management platform, and they play a crucial role especially in the information release subsystem. Before the arrival of meteorological disasters, small automatic weather stations can quickly release early wa...
The safe flood - season operation of reservoirs has always played a crucial role in China's flood prevention and control work, and it is also extremely challenging. Small and medium - sized reservoirs have become the weak links in the entire flood - prevention system. At present, most of these s...
