   <abstract xml:lang="ru">
    <p>Статья посвящена анализу воздействия дыма от горящей растительности (пала травы) на снижение дальности видимости и дорожно-транспортную аварийность. На основе анализа публикаций в отечественных средствах массовой информации&#13;
и статистических данных о дорожно-транспортных происшествиях Госавтоинспекции Российской Федерации установлено, что из всех аварий, случившихся в условиях недостаточной видимости из-за природных пожаров, более половины произошли из-за пала травы; для таких аварий характерна массовость и высокий травматизм. Обосновывается применение усовершенствованной формулы Траберта для расчета дальности видимости в условиях замутнения атмосферы дымом, приводятся результаты экспериментально-расчетных исследований снижения дальности видимости в зависимости от размера&#13;
и концентрации аэрозолей в дыме на разном удалении от модельных очагов горения травянистой растительности. Подтверждено, что на процесс горения и дымообразующую способность оказывают влияние вид растительного горючего материала, поверхностная плотность и погодные условия.</p>

    <p>The paper describes the impact of smoke from burning vegetation (grass burning) on visibility and road accidents. Based on the analysis of publications in domestic media and traffic accident statistics of the State Traffic Safety Inspectorate of the Russian Federation, it was found that of all accidents that occurred in conditions of poor visibility due to wildfires, more than half occurred due to grass burning; in such accidents there are many participants and high injury rates. We also confirmed the validity of the improved Trabert’s formula for estimating visibility in the air, clouded with smoke, and described the results of experimental and computational studies on visibility depending on the size and concentration of aerosols in smoke at different distances from model grass fires. It is confirmed that the combustion process and smoke-capacity are affected by the type of plant combustibles, surface density, and weather conditions.</p>
