Abstract

In order to provide more scientific decision support for traffic control so as to improve driving safety under ice and snow conditions, vehicle force and driving behaviors were analyzed, and possible rear-end collision and side-slip accidents were discussed based on drivers' characteristics. Then, a CAM of two-lane one-way possible traffic accidents under ice and snow conditions was established. Finally, through traffic simulation, this model was validated, and flow-density characteristics and accident probability with control measures were analyzed. The results indicate that different measures should be taken to reduce accident probability according to specific ice and snow conditions and road geometry. It can be reduced by 41. 02% through using deicing salt and setting speed limit on horizontal road covered with smooth ice film, and more than 34. 20% if different speed limits were set on horizontal road in other ice and snow environment. It can also be reduced effectively by using deicing salt combined with classified speed-limiting measures on longitudinal slope road. And anti-skid chains or winter tires should be installed for vehicles on longitudinal slope road under smooth ice film so as to improve driving safety. © 2019 China Safety Science Journal
