Road traffic guiding method based on positioning system and road traffic guiding system

Abstract

The invention discloses a road traffic guiding method based on a positioning system, and the road traffic guiding method is realized by a road traffic guiding system which is composed of a vehicle positioning system, a vehicle-mounted signaling machine, a pavement signaling machine, an intelligent road traffic signboard, a central monitor and a communication transmission system. In haze days, vehicles on the pavement are guided, and the approaching distance of vehicles is identified and predicted; when emergent ground water or liquid accumulation, icing, fire hazard or pavement collapse and deformation occur in the pavement, early warning is timely and remotely emitted to the driving vehicles, more serious accidents are avoided, safe driving is helped, and the utilization rate of highway is improved; and the method and system are characterized by convenient realization and high practicality.

Description

technical field [0001] The invention relates to a positioning system-based highway traffic guidance method and a road traffic guidance system, which belong 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 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 realiz...

[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 bad, such as fog and haze, 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 of the vehicle. , due to the limitation of the driver's sight distance, he can't know the road ahead in time, which is easy 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 the highway traffic; this will reduce the utilization rate of the highway, and also bring inconvenience to people's daily life and economic activities; In the event of ice, accidents, fires, traffic accidents, and road surface collapse and deformation, the existing road traffic management system cannot issue early warnings to driving vehicles in time, which is likely to cause larger accidents
