Description

Technical Field

[0001] The invention relates to the technical field of active traffic control and road warning, and in particular to a highway vehicle guidance and warning system. Background Art

[0002] As people's living standards improve, the number of motor vehicles in my country is increasing. As of the end of September 2023, it has reached 430 million. As the mileage of the highway network increases year by year, it has also become an important part of the urban transportation network. This has caused some issues to attract widespread attention. For example, accidents caused by drivers' unclear about the road conditions ahead and visibility of less than 100 meters in some areas due to weather reasons are undoubtedly a safety hazard when driving on highways.

[0003] In the prior art, the equipment that provides real-time traffic information and warning information to drivers is mainly variable information signs installed on highways and warning lights installed on isolation belts or gantries. This type of equipment not only requires a large initial investment, but also cannot effectively guide vehicles.

[0004] In the prior art, the facilities that can guide vehicles on highways are mainly lane markings and lane indicators. However, these devices also have their disadvantages. At night, the visibility of lane markings is reduced, and the information provided by the markings is not easily perceived by the driver. In addition, the guidance of vehicles also requires the driver to make his own decisions based on his judgment of relevant information, which sometimes causes the driver to misunderstand the instructions and cause accidents.
