driving guidance system

Abstract

The invention introduces a driving guidance system composed of a wireless positioning repeater station, a vehicle-mounted signal machine, a road surface signal machine, an intelligent road traffic sign, a central monitor, and a communication transmission system. On the pavement roadway, the driving guidance and the warning of the vehicle approaching distance signs are provided for the running vehicles, and the distant display warning is issued to the driving vehicles in time to avoid accidents, achieve the purpose of assisting safe driving and improving the utilization rate of the expressway, and it is convenient and practical to implement strong features.

Description

technical field [0001] The invention relates to a driving guidance system and belongs to the field of highway 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 cannot clearly show the direction of the roadway ...

[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
