A method for publishing traffic accident avoidance information and a cloud server

Abstract

The invention discloses a method for publishing traffic accident avoidance information and a cloud server. The method includes: the cloud server determines the severity level of the accident and the avoidance plan according to the accident information reported by the vehicle; The processing time is to determine the length of the road section affected by the accident; the cloud server sends the accident avoidance information including the accident information, the avoidance plan and the estimated processing time to the vehicles in the corresponding road section according to the length of the road section affected by the accident. The application of the present invention can provide drivers with more accurate early warning of traffic accidents and more effective reminders, so that drivers can take measures such as planning routes in advance and slowing down to avoid congestion, thereby avoiding large-scale congestion caused by small accidents, secondary accidents, etc. Accidents, etc., improve the traffic efficiency of urban roads.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a method and a cloud server for publishing traffic accident avoidance information. Background technique [0002] Traffic congestion is currently a common problem in China's large and medium-sized cities, resulting in a lot of wasted time and resources, which affects people's lives to a certain extent. Most traffic jams are caused by minor accidents on the road. Often a small scratch will cause several kilometers of congestion. Only when you are very close to the scene of the traffic accident can you know the road conditions. At this time, a large deceleration or emergency lane change is easy to cause congestion. If the response is not timely, it is more likely to cause a secondary accident (rear-end collision or scraping, etc.), resulting in a larger area. of congestion. [0003] An existing method for releasing traffic accident information of real-time road conditio...

AI Technical Summary

Problems solved by technology

[0004] However, in practical application, the inventors of the present invention found that the existing method for releasing traffic accident information is inaccurate in information release content, which is not conducive to the driver's proper response.

In most cases, car owners can only know that the road is congested again based on the published information, but they do not know the cause of the road congestion, the length of the traffic congestion, and the time required for the road to return to normal, and cannot make timely route changes and choose to bypass the congested road section Choose to detour, or make timely adjustments to upcoming work or activity plans during traffic jams, which can also cause adverse effects such as road rage

[0005] For example, the driver cannot know the processing time required for the accident, so he cannot choose whether to detour or slow down; for another example, in some cases, a very serious accident may occur, resulting in long congested road sections, and the existing technical methods At this time, the congested road section may have exceeded the scope of the accident information distribution, resulting in the failure of subsequent vehicles to receive the accident information in time and take measures to cause more serious congestion
