Analysis of the Causes of Secondary Accidents on Highways and Preventive Measures
Based on the highway traffic accident data in Anhui Province,the accident spatial and temporal distribution characteristics,morphological characteristics,the distribution characteristics of secondary accidents under the influence of weather and the influence characteristics of primary accidents on secondary accidents were analyzed by descriptive statistics.The results showed that:the type of secondary accidents on highways is mainly rear-end;the beginning of the month,the first quarter of each year and the last day of each week are the high incidence of secondary accidents.The secondary accidents are mainly distributed in complex traffic nodes such as traffic hubs and service area entrances and exits;the primary accidents have a significant influence on the secondary accidents.On this basis,the causes of secondary accidents in terms of primary accidents,traffic flow and road environment are further explored,and targe-ted preventive countermeasures are proposed with a view to reducing the incidence of secondary accidents on motorways and improving road traffic safety.
