Embodiment Construction

[0047] Method example:

[0048] This embodiment provides a smart road safety early warning method, which is used to judge the safety performance of the road in dense fog, and send an early warning signal when the safety performance of the road is low, so as to ensure the safety of vehicles and pedestrians on the road , improve the reliability of road safety early warning.

[0049] The intelligent road safety early warning method provided by this embodiment, its flow process is as follows figure 1 shown, including the following steps:

[0050] (1) Detect the fog concentration on this section of road, and calculate the visible distance of this section of road according to the fog concentration.

[0051] A fog concentration detection device is arranged at every set distance beside this section of the road. The control unit of this section of the road communicates with each fog concentration detection device. fog concentration. For example, there are m fog concentration detect...

Abstract

The invention provides an intelligent highway safety early warning method and system, and the early warning method comprises the following steps of detecting the fog concentration on a highway, and judging and calculating the visible distance according to the fog concentration; when the visible distance is smaller than a set safe distance, acquiring a road condition simulation image of each vehicle at set intervals and sending the road condition simulation images to the corresponding vehicles; and acquiring the driving speed and the driving direction of each vehicle on the road, judging whether an accident occurs or not according to the driving speed and the driving direction of each vehicle, and if so, sending the alarm information to the corresponding vehicle. According to the technicalscheme provided by the invention, the vehicle can obtain the road condition simulation image of the vehicle once at set intervals, so that a driver can observe the fog-free road condition picture information once at set intervals, the road condition can be visually seen, the alarm effect is better than that of an alarm mode that only the alarm information is sent out, and the problem that in the prior art, a road alarm system is poor in alarm effect can be solved.

Description

technical field [0001] The invention belongs to the technical field of road safety detection, and in particular relates to a smart road safety early warning method and an early warning system. Background technique [0002] Smart roads can guide and divert traffic flow in time and space through the collection and transmission of traffic information, avoid road congestion, enhance the safety of road users, and reduce traffic accidents. And improve the expressway transportation environment, so that vehicles and drivers can run safely, quickly, smoothly and comfortably on the expressway. [0003] Due to the limitations of natural conditions and geographical conditions, dense fog occurs on many highways on specific road sections. Traffic accidents caused by fog have brought great losses to people's lives, property and social and economic losses. [0004] When dense fog occurs on the road, the impact on the driver mainly has two aspects: the first is the impact on the driver's s...
