Roadway marking method and roadway marking system based on radar detection

Abstract

The invention introduces a roadway marking system based on radar detection realized by a roadway marking system composed of a vehicle-mounted signal machine, a road surface signal machine, an intelligent road traffic sign, a data transmission and forwarding station, a central monitor, and a communication transmission system. The marking method, in the fog and haze weather, can realize the roadway marking and vehicle approaching distance marking and forecasting of running vehicles on the roadway of the highway, and timely send out distant display warnings to driving vehicles to avoid accidents and achieve auxiliary The purpose of driving safely and improving the utilization rate of expressways is that it is easy to implement and has strong practicability.

Description

technical field [0001] The invention relates to a roadway marking method and a roadway marking system based on radar detection, belonging to the field of road traffic control. Background technique [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 the control of traffic at plane intersections or in a local area, and it is set at a specific location. It cannot realize the long-distance, continuous, and dynamic display of the occupancy of the linear roadway, the driving status of the vehicle, and the distance between vehicles. When the atmospheric visibility conditions are bad, such as fog and haze, relying on vehicle lighting, street lights, existing highway signal systems and reflective signs ...

[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 the control of traffic at plane intersections or in a local area, and it is set at a specific location. It cannot realize the long-distance, continuous, and dynamic display of the occupancy of the linear roadway, the driving status of the vehicle, and the distance between vehicles. When the atmospheric visibility conditions are bad, such as fog and haze, relying on vehicle lighting, street lights, existing highway signal systems and reflective signs cannot clearly show the direction of the roadway and the distance between vehicles to the driver. Due to the limitation of the driver's sight distance, it is impossible to know the road ahead in time, which is likely to cause traffic accidents; therefore, in foggy weather, it is usually followed by warning vehicles to slow down or close the road to avoid traffic accidents. This situation is common in high-speed roads. In road traffic; this will reduce the utilization rate of expressways and bring inconvenience to people's daily life and economic activities
