Problems solved by technology

[0002] In the existing road traffic control signal system, as well as in the existing auxiliary road traffic control system, such as traffic lights at intersections and red light camera systems, camera monitoring systems, electronic card information announcements, street lights, and radio station announcements, all are It is used for level crossing or traffic control within a local area, and it is set at a specific location; when various existing vehicle positioning systems are applied to road traffic, it is usually to set up a navigator on the vehicle to provide the vehicle with a starting and ending route. guide, or the central control room understands the current running position of each vehicle; none of the above-mentioned existing technologies can realize the long-distance, continuous and dynamic monitoring of the occupancy of the linear roadway, the driving status of the vehicles, and the distance between vehicles. It should be shown that when the atmospheric visibility conditions are poor, such as foggy, rainy season and night weather with poor visibility, relying on vehicle lights, street lights, existing highway signal systems and reflective signs cannot clearly show the vehicle driver. The direction of the road and the distance between vehicles are limited by the driver's sight distance, and the situation of the road ahead cannot be understood in time, which is likely to cause traffic accidents; therefore, in the case of fog and haze, it is usually followed by warning vehicles to slow down or close the road. To avoid traffic accidents, this situation is common in expressway traffic; this will reduce the utilization rate of expressways, and also bring inconvenience to people's daily life and economic activities; in addition, when sudden abnormalities appear on the road surface, For example, when the ground accumulates water, icing, fire accidents, traffic accidents, and road surface collapse and deformation, the existing road traffic management system cannot issue early warnings to driving vehicles in time, which may easily lead to greater accidents

Abstract

The invention relates to a highway traffic guidance system composed of a vehicle positioning system, a communication transmission system and a signal system and a highway traffic guidance method used for implementing the highway traffic guidance system. According to the invention, traffic guidance and vehicle approaching distance marker forecasting can be carried out on running vehicles on highway pavement traffic lanes under poor-visibility weather conditions such as occurrence of fog and haze, rainy seasons, night and the like, so that a remote display early warning is sent to the running vehicles when sudden impounded surface water and liquid, freezing, accidents, fire and collapse deformation of the highway pavement happen, thereby avoiding greater accidents, and achieving the purposes of assisting safe driving and improving the utilization ratio of highway. In addition, the method and the system provided by the invention have the characteristics of convenient implementation and high practicability.
