This invention provides a highway fog emergency monitoring system, method, and medium based on an Internet of Things (IoT) big data model. The system includes an emergency monitoring and management platform, which is configured to: predict fog forecast information for the monitored road segment at a future time based on micro-meteorological data and geographic data of the road segment to be monitored within a preset time period; the micro-meteorological data is collected through monitoring points deployed on the monitored road segment; generate emergency commands based on the fog forecast information and predicted traffic information at the future time; and control the opening and closing of intelligent road studs and laser lane systems based on the emergency commands.

This utility model belongs to the technical field of traffic safety auxiliary equipment, specifically relating to an improved reflective road stud. The reflective road stud includes a light-transmitting base, a fixing box, and a return spring. The light-transmitting base is housed in the fixing box, and the return spring applies a supporting force towards the road surface to the light-transmitting base. The light-transmitting base has a raised pavement marker portion. The pavement marker portion is made of light-transmitting material, and its side has a first refractive surface. Light is reflected by the reflective material coating and emitted from the first refractive surface, forming a reflective signal. The light-transmitting base has a movement trajectory that moves up and down within the fixing box as the return spring compresses or resets, and the pavement marker portion has a movement trajectory that enters or leaves the fixing box as the return spring compresses or resets. Under the action of external forces such as vehicle rolling, the pavement marker portion sinks and resets with the support force of the return spring. The return spring absorbs the impact force of the wheel on the road stud, effectively protecting the light-transmitting base and the pavement marker portion, and extending their service life.
