Embodiment 1

[0029] Embodiment 1: The present invention provides a highway accident monitoring and prompting method, which specifically includes the following steps:

[0030] Step0.1: Divide the adjacent toll station A and B of the expressway into multiple sections according to the distance length Δl {X 1 ,X 2 ,...,X n }, and follow different lanes {y 1 ,y 2 …Y m }The section {X 1 ,X 2 ,...,X n }Further refined into

[0031] specific:

[0032] Record the total distance between the expressway toll station A and B section l=5000m, record the distance length Δl=1000m, then n=l / Δl=5, that is, there are 5 sections between the toll stations, and record the number of lanes of the road section m =3, the section set is: {X 11 ,X 12 ,X 13 ,X 21 ,X 22 ,X 23 ,X 31 ,X 32 ,X 33 ,X 41 ,X 42 ,X 43 ,X 51 ,X 52 ,X 53 }.

[0033] Step0.2: According to different sections and different lanes Set the corresponding section and corresponding traffic lane The maximum speed threshold of the vehicle And vehicle minimum ...

Embodiment 2

[0051] Embodiment 2: The present invention uses the section lane division method and the video vehicle detector speed measurement method to intelligentize the occurrence of highway accidents based on the relationship between the average vehicle speed and the maximum vehicle speed threshold and the minimum vehicle speed threshold. Monitoring and prompting. If a section to be endangered or a dangerous section is detected, an alarm message will be displayed on the prompt screen of the preamble section of the section to remind vehicles coming from behind. In addition, the section information will be sent to the traffic management. Department to deal with dangerous accidents. Compared with the prior art, the present invention realizes the visualization, systematization and intelligence of highway accident monitoring, and can fundamentally improve the management level of the highway.

Abstract

The invention relates to a highway accident monitoring and prompting method, and belongs to the technical field of highway safety. A sector lane division method and a video vehicle detector speed measuring method are used, and intelligent monitoring and prompting are carried out on highway traffic accidents with the aid of the relationship among an average vehicle running speed, the maximum vehicle running speed threshold and the minimum vehicle running speed threshold; if it is monitored that a to-be-dangerous sector or a dangerous sector exists, warning information is displayed in a front-sequence sector prompt screen of the section so as to remind a rear vehicle, and road section information is sent to the traffic management department for handling dangerous accidents. Compared with theprior art, highway accident monitoring system achieves visual, systematic and intelligent highway accident monitoring, and the management level of a highway can be fundamentally improved.

Description

Technical field [0001] The invention relates to the technical field of expressway safety, and in particular to a method for monitoring and prompting an expressway accident. Background technique [0002] Nowadays, there are more and more motor vehicles, and the probability of traffic accidents is also increasing. Especially on highways, severe traffic jams, vehicle accidents, and even serial collisions frequently occur due to various weather problems such as heavy fog, blizzard, heavy rain and other bad weather with low visibility. Failure to deal with a traffic accident in time will often cause danger to subsequent vehicles. [0003] At present, the monitoring of dangerous accidents on expressways is usually only the way of video monitoring. It is learned by manually viewing the monitoring video or receiving an alarm call. This is not timely for the handling of dangerous accidents, especially during the unhandled period of dangerous accidents. Later, the vehicle was very dangerou...
