Visibility Meter: Enhancing Traffic Safety

Modern highway construction is of great significance to national development, but it is closely related to meteorological conditions. Good meteorological conditions can ensure the smooth progress of highway construction, while bad weather will bring many obstacles. Heavy rain may wash away the roadbed, strong winds may affect the stability of construction equipment, and high or low temperatures will also affect the performance of construction materials. After the highway is put into use, meteorological conditions are equally crucial. Heavy fog will reduce visibility and affect driving safety; icy and snowy weather is likely to cause the road surface to slip and increase the risk of traffic accidents. Therefore, in highway construction and operation, meteorological conditions must be fully considered and effective measures must be taken to ensure highway safety and efficiency.

At a time when the Internet of Things technology is becoming more and more mature, realizing functions such as real-time online monitoring, intelligent analysis and prediction through the Internet of Things information platform has become a trend. Following this trend, how should we use modern Internet of Things information technology to conduct scientific meteorological monitoring to avoid frequent traffic accidents? First, many intelligent sensors can be set up at key parts of the road to collect meteorological data in real time, such as temperature, humidity, wind speed, rainfall, etc. These data are transmitted to the central processing system through the Internet of Things for rapid analysis and processing. Once bad weather conditions are detected, an alarm is sent to the driver in time to remind him to pay attention to safety. Second, using big data and artificial intelligence technology, conduct in-depth analysis of historical meteorological data and traffic accident data to explore the correlation law between meteorological conditions and traffic accidents, and provide a basis for formulating more scientific traffic management strategies.

Visibility meter is an atmospheric visibility monitoring instrument controlled by a microprocessor according to the principle of forward scattering of light. It emits infrared light pulses, then measures the forward scattering light intensity of suspended particles in the atmosphere, and uses an appropriate algorithm to convert the measured value into a meteorological visibility value.

In actual application scenarios, the Visibility meter can help traffic management departments quickly and accurately understand traffic conditions and judge the degree of danger, thereby effectively protecting the lives of drivers, improving traffic safety, reducing casualties, and reducing the probability of accidents. At present, this product has been widely used in sections such as expressways and urban expressways.
