  • Essay / Forecasting Atmospheric Visibility for Road Safety

    Atmospheric visibility forecasting is a critical task nowadays. On the one hand, low visibility due to adverse weather conditions such as fog, mist, smog or haze presents many challenges for drivers, including strong negative visual effects and a decreased ability to see at through the air, which is really important for driving safety. These challenges arise due to the reduction in luminance contrast. A rapid decrease in the contrast of objects in the field of view, scattered light results in a complete loss of object detection or object recognition becomes difficult and the visual response time increases significantly.

In dense fog, scattered light becomes more harmful and small objects approach the visibility threshold. This in turn leads to fatal incidents on the roads. In fact, according to statistics provided by the United States National Highway Traffic Safety Administration (NHTSA), 28% of all accidents occur in adverse weather conditions and the World Health Organization (WHO) has stated that one person dies every 25 seconds from road injuries. [x1]. Furthermore, in disturbed weather conditions, the estimated average of the total number of annual accidents is approximately 31,385, representing more than 511 road deaths and almost 12,000 injuries each year due to accidents in climates with low visibility [P1]. Additionally, zero visibility can trigger many delays and cancellations at the airport. This not only causes huge losses for airports and airlines, but also affects public travel. At the same time, flight safety and low visibility are closely related, since low clouds or low visibility are a common cause of flight accidents [E3, E10, E13, E14, E16]. Like the aviation industry, low visibility also affects river transport operations [E4, E22]. On the other hand, the degradation of visibility greatly reduces the image quality of a captured outdoor scene. Since visibility is much better on a clear day than in air polluted by large amounts of water droplets or dust particles in the atmosphere. The main reason for degraded outdoor image quality in foggy or foggy conditions is the presence of large amounts of airborne fog or fog particles, which cause most of the image to be scattered. light before reaching the camera or other optical device. As a result, a blur occurs throughout the image [1, 2]. These types of degraded and inconspicuous image scenes significantly influence computer vision applications and embedded systems. For example, navigation, tracking applications and surveillance systems; exterior recognition, detection and segmentation; intelligent transportation systems; optical and camera based applications which are used in military and security agencies etc. Currently, many security and traffic monitoring cameras are deployed across the country and various vision-based applications are widely used.
