Road early warning method and road early warning system based on satellite positioning

Abstract

The invention introduces a road warning method based on satellite positioning which is realized by a road warning system consisting of a vehicle-mounted satellite positioning signal machine, a pavement signal machine, a satellite calibration repeater station, an intelligent road traffic signboard, a central monitor and a communication transmission system. The method can guide traffic for the driving vehicles and forecast the approaching distance and warn and mark the vehicles on a road of a highway pavement in a haze weather state to avoid accidents so as to realize the purpose of assisting safe driving and improving the utilization ratio of highway. The method and system have the characteristics of convenient implementation and strong practicality.

Description

technical field [0001] The invention relates to a road early warning method and a road early warning system based on satellite positioning, and belongs to the field of road traffic control. Background technique [0002] When the existing satellite positioning system is applied to road traffic, it is usually to set up a navigator on the vehicle to provide driving route guidance for the vehicle, or to know the current running position of each vehicle from the central control room, but it cannot realize the roadway ahead. The occupancy status of other vehicles, the driving status of other vehicles, and the distance between vehicles are displayed in a long-distance, continuous, and dynamic manner. When the atmospheric visibility conditions are poor, such as foggy weather, vehicle lighting, street lights, existing highway signal systems and reflective The signs cannot clearly show the direction of the roadway and the distance between vehicles to the driver of the vehicle. Due to ...

[0002] When the existing satellite positioning system is applied to road traffic, it is usually to set up a navigator on the vehicle to provide driving route guidance for the vehicle, or to know the current running position of each vehicle from the central control room, but it cannot realize the roadway ahead. The occupancy status of other vehicles, the driving status of other vehicles, and the distance between vehicles are displayed in a long-distance, continuous, and dynamic manner. When the atmospheric visibility conditions are poor, such as foggy weather, vehicle lighting, street lights, existing highway signal systems and reflective The signs cannot clearly show the direction of the roadway and the distance between vehicles to the driver of the vehicle. Due to the limitation of the driver's sight distance, they cannot understand the road conditions ahead in time, which may easily cause traffic accidents; Closing roads to avoid traffic accidents is common in expressway traffic; this will reduce the utilization rate of expressways and bring inconvenience to people's daily life and economic activities
