Road traffic safety relies heavily on the visual environment of the road surface. Weather conditions such as heavy fog,storms, rain, snow, and patch fog can rapidly reduce road visibility, instantly increasing the risk of vehicle travel and serving as a major trigger for rear-end and pile-up. In the past, road visibility monitoring mostly relied on fixed monitoring stations and manual visual judgment. Fixed equipment is stationary and immobile, leaving large monitoring blind spots, while manual judgment highly subjective and prone to errors, making it difficult to promptly capture sudden visibility changes in local road sections. The WX-BN20 portable visibility monitor liberates road visibility monitoring the constraints of fixed locations, enabling mobile monitoring anytime and anywhere. It fills the monitoring gap for temporary road sections, remote road sections, and sudden weather scenarios, becoming a lightweight intelligent new for traffic security, emergency control, and road inspection.

In daily traffic inspection, emergency prevention and control in severe weather, road construction control, and rural road security work, traditional visibility monitoring equipment lacks flexibility, making it difficult to adapt to diverse and temporary monitoring needs, and unable to fully cover the safety monitoring work of various road sections. The WX-BN2 portable visibility monitor features core advantages of being lightweight and easy to carry, ready to use on demand, and simple to operate. It requires no complex setup and no professional debugging, completely doing with the drawbacks of traditional equipment being bulky, fixed, and cumbersome to deploy, making it suitable for all kinds of road conditions and complex weather environments. Whether it is highway branches, roads, mountain curves, or temporary construction road sections and scenic area passages, visibility monitoring can be quickly carried out, making road visual environment monitoring more flexible and efficient, perfectly fitting development needs of modern fine-grained traffic control.

The WX-BN20 portable visibility monitor enables full-domain coverage and dynamic control of road environment monitoring. The device is limited by site and environment, can be carried in vehicles, and moved along with inspections. It can perform fixed and mobile monitoring for accident-prone road sections, patch fog-prone areas and construction road sections, accurately capturing short-term and local visibility changes. Compared to traditional monitoring modes, it can quickly respond to road condition changes brought by sudden weather, providing real-, authentic, and effective environmental data for traffic management personnel. It bids farewell to the backward mode of relying on experience for judgment and feedback for disposal, ensuring that every traffic control is data-supported, more scientific, and more accurate.

In addition to public road traffic control, this device also plays an important role in scenarios such as industrial park passages, area roads, port terminals, and rural road networks. Most of these sites have no fixed monitoring equipment installed, and visibility monitoring under severe weather has long been a blank. Rain, snow and sandstorm weather can easily trigger safety accidents such as vehicle scrapes and collisions within the sites. The portable visibility monitor is suitable for various non-municipal road scenarios, has a low for use, and strong mobility. It can flexibly adjust monitoring points according to weather changes and control needs, carry out normalized environmental monitoring, promptly discover low-visibility safety hazards, assist staff in carrying out speed limits, guidance, and temporary control, effectively regulate the passage order within the sites, and comprehensively guarantee the passage safety of various sites。
