Highway strong crosswind section speed early warning control method and system

The invention discloses a highway strong crosswind section speed early warning control method and a highway strong crosswind section speed early warning control system, which relate to the technical field of traffic early warning. The highway strong crosswind section speed early warning control system comprises an information detection module, an information processing module and an information early warning publishing module. According to the highway strong crosswind section speed early warning control method, stress analysis is carried out on sideslip and rollover conditions possibly generated by different vehicle models on a strong crosswind road section; a speed limit optimization model is established, and a highway variable speed limit control strategy under the influence of strong crosswind is formulated on the basis of the speed limit optimization model; and finally, an early warning system is designed and early warning levels are divided, thereby effectively guaranteeing safetyand stability of vehicle
