What do you mean by high-speed fog transfer?

When there is heavy fog in expressway, the traffic management department takes measures to ensure traffic safety by controlling and diverting vehicles at different levels.

When foggy weather occurs in expressway, the visibility will be obviously reduced, which will bring great safety hazards to drivers. In order to prevent traffic accidents, the traffic management department will control expressway according to the actual situation. Diversion measures may include speed limit, traffic restriction, closure of some road sections or prohibition of specific vehicles. This can reduce the density of vehicles, reduce the risk of traffic congestion and accidents, and ensure the safe and smooth road traffic.
