Review of Technologies for Mitigating Traffic Accidents in Foggy Conditions

Traffic accidents in foggy conditions represent a significant risk in countries such as Peru, where topography and weather conditions vary considerably. In 2023, the Tax Administration Service of Lima (SAT) reported around 43,000 accidents, with 4% deaths, 66% injuries and 30% runovers. This study employed the PRISMA methodology and bibliometric analysis in Scopus, using Boolean algorithms to filter scientific articles on devices and methods to mitigate accidents in fog between 2002 and 2025. 387 documents were analyzed and processed with RStudio and Google Collaboratory. Of the total, 73.7% corresponded to articles, 24.5% to conference papers and 1.8% to reviews. China led production with 179 documents, followed by the United States with 68. The most relevant advances include adaptive lighting systems and driver assistance devices, such as cameras and radars, which improve visibility and reduce the risk of collisions. Despite the progress, the study recommends developing more accessible and efficient technologies adapted to Peruvian conditions. The use of real-time monitoring and artificial intelligence algorithms is transforming road safety, but more research and collaboration between scientists and engineers is needed to improve road safety, especially in regions with high incidences of fog.
