Embodiment 1

[0032] This embodiment provides a method for guiding and laying out cloud fog on expressways, such as figure 2 shown, including the following steps:

[0033] Step S101, measuring the route of the highway in the group fog section;

[0034] Step S102, setting display screens and voice playback devices at both ends of the Tuanwu road section;

[0035] Step S103, evenly arrange several radars, several guide lights and warning lights on both sides of the foggy road section;

[0036] Step S104, setting up road surveillance cameras at both ends of the Tuanwu road section for photographing and recording passing vehicle information;

[0037] Step S105, when it is detected that the visibility of the foggy road section is lower than the first preset threshold, turn on the guide light, and control the display screen to give a text prompt; that is, when the visibility of the foggy road section is lower than 200 meters, control Display text prompts;

[0038] Step S106, when the radar d...

Abstract

The invention provides an expressway agglomerate fog guide layout method. The method comprises the following steps: measuring an expressway route of an agglomerate fog section; arranging a display screen and a voice playing device at two ends of the agglomerate fog road section; uniformly arranging a plurality of radars, a plurality of guide lamps and warning lamps on the two sides of the agglomerate fog road section; arranging road monitoring cameras at the two ends of the agglomerate fog road section; according to the detected visibility information, controlling the playing mode of prompt information and the turn-on of a guide lamp or a warning lamp; and when the radar detects that the target vehicle is overspeed or the distance between the target vehicle and the front vehicle is smaller than a distance threshold value, controlling a warning lamp near the target vehicle to flicker according to a preset frequency. The driving state of the vehicle and the distance between the front vehicle and the rear vehicle are monitored through the radar, and a driver is warned through flickering of the red light, so that the driver knows the state of the driver and can adjust the driving state in time, the driving safety of the vehicle is ensured, and traffic accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a method for guiding and laying out cloud fog on an expressway. Background technique [0002] When the vehicle is driving, due to some unavoidable natural conditions, the information that the driver can obtain is reduced, and the human perception ability will also be affected, resulting in changes in the driver's psychology and driving behavior. Things lose a correct judgment, resulting in a car accident. Especially in the foggy road section with low visibility, the low-visibility fog makes the driver's field of vision narrow and blurred, greatly weakening the ability to judge things around the car, and easily causing a certain degree of panic to the driver's psychology. , causing the driver to make a wrong judgment when driving the vehicle, resulting in a car accident. [0003] Most of the existing intelligent fog area guidance systems and layout devices are provided with...
