Visibility Detector and Visibility Observation System for Traffic Safety

In our daily life, we often encounter severe weather such as haze and patchy fog. During these times, the atmospheric visibility is extremely low, just like a veil covering our eyes. It's a very unpleasant feeling, and such conditions are also prone to causing traffic accidents. So, is there a way to detect the problem of low atmospheric visibility? The answer is yes. There is a new - type instrument on the market - the visibility detector, which can accurately measure the data of atmospheric visibility.

Adverse weather conditions, such as water - logged road surfaces, thick snow cover, heavy rain and snow, patchy fog, dense fog, sandstorms, rainstorms, blizzards, smoke pollution, as well as vehicle speed and traffic volume, etc., can reduce the atmospheric visibility and have a severe impact on safe operation. According to statistics, on expressways, traffic accidents caused by dense fog and icing - induced skidding account for approximately 25% of the total number of accidents. The accident rate at night on expressways is 1 to 1.5 times higher than that during the day, and the accident rate on expressways under adverse weather conditions is 10 times that of normal conditions.

According to the recommended plan, it is necessary to standardize, normalize, and intellectualize the traffic risk management of severe weather in specific road sections, and minimize the impact of severe weather on road traffic safety. As a professional device for monitoring atmospheric visibility, the visibility tester is of great significance for environmental protection and traffic safety.

This project aims to plan and construct an efficient and accurate visibility observation system to assist the traffic management department in ensuring road traffic safety. When low - visibility meteorological phenomena occur, the visibility observation system mainly relies on the front - end monitoring modules such as meteorological visibility to conduct data analysis, issue timely alarms, and upload the information. The on - duty personnel in the command center will receive the alarm information through the central platform or mobile phones. After confirmation, they will immediately initiate speed - limit instructions. When the meteorological conditions return to normal, the system will automatically restore to the original designed speed - limit state of the road. This system consists of three parts: front - end equipment, data transmission, and remote control center.
