Intelligent Ways of Reducing Secondary Accidents on Roads

Nowadays traffic collisions in highways is frequent and they not only cause delay in trips but they also may lead to secondary accidents which may be 6 times more dangerous than the primary accident. In order to manage traffic collisions, reducing secondary accidents is a key factor. However, enough attention has not been paid to secondary accidents, which is because of the random nature of these accidents. As a result, most of the past studies have focused on the definition and recognition of secondary accidents. After recognizing secondary accidents, defining the factors that affect them is the main procedure to reduce this kind of accidents. In fact, when the key factors influencing a phenomenon is not yet known, presenting methods to deal with it, is useless. Therefore, many of the past studies have focused on the key factors that cause a secondary accident, such as road geometry, traffic condition, weather and vehicle characteristics. After defining the key factors affecting secondary accidents, it is possible to reduce them, and some of the previous studies have presented these methods. In this article, a general review on all of the 3 aforementioned categories of study, has been provided.
