Abstract

In order to reduce traffic accident risks of mountainous two-lane highways passing through villages and towns segments, SEM and N-K model were constructed based on road alignment, village and town environment as well as traffic accident data. Then, coupling effects of access roads and environment, vehicle and road alignment on traffic accident scale of such mountainous highways were explored, and influence of road-village distance, access road type and quantity, and intersection type on the accident risk and their coupling effects were quantitatively analyzed. The results show that access roads have significant impacts on the accident risk of the above-mentioned highways, and it has a strong coupling effect with horizontal curve factors and vertical curve ones. Road-village distance and intersection type have direct significant effect, while number and type of access roads have only indirect significant effect. The coupling risk of roads detouring villages for more than 100 meters and mechanical tillage road is maximum, with risk coupling degree at 0. 359 6, while that of machine tillage road and three access roads is minimal, with coupling degree at 0. 000 1. © PHYSOR 2022 China Safety Science Journal.
