roadway signal system

Abstract

The invention discloses a roadway labeling method based on transmission detection, which is realized by a roadway signal system consisting of a vehicle-mounted signal machine, a road signal machine, a data transmission repeater station, an intelligent road traffic sign board, a central monitor and a communication transmission system. Under a hazy weather state, roadway labeling and vehicle approaching distance labeling and advance-noticing can be carried out on an operation vehicle on a road pavement roadway, so that an accident is avoided to achieve purposes of assisting safe driving and improving highway utilization rate; moreover, the method has characteristics of being convenient to implement and strong in practicability.

Description

technical field

[0001] The invention relates to a roadway signal 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 level intersections or in local areas, 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 lights, street lights, existing highway signal systems and reflective signs cannot clearly show the direction of the roadway and th...
