Method for issuing traffic accident avoidance information and cloud server

Abstract

The invention discloses a method for issuing traffic accident avoidance information and a cloud server. The method comprises the steps that: the cloud server determines a severity level and an avoidance plan of an accident according to accident information reported by a vehicle; the length of an accident-affected road segment is determined according to an estimated processing time corresponding tothe severity level; and the cloud server sends accident avoidance information including the accident information, the avoidance plan and the estimated processing time to the vehicle in the corresponding range road segment according to the length of the accident-affected road segment. By applying the method and the cloud server, a more accurate warning of a traffic accident and more effective reminding can be provided for a driver, thus large-scale congestion, a secondary accident and the like caused by a small accident are avoided, and the traffic efficiency of an urban road is improved.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a method for publishing traffic accident avoidance information and a cloud server. Background technique [0002] Traffic congestion is currently a common problem in large and medium-sized cities in China, causing a lot of waste of time and resources, and affecting people's lives to a certain extent. Most of the traffic jams are caused by small accidents on the road. Often a small scratch can cause several kilometers of traffic jams. Only when you are very close to the scene of a traffic accident can you know the road conditions. At this time, a temporary slowdown or an emergency lane change will easily cause congestion. congestion. [0003] An existing method for distributing traffic accident information on real-time road conditions is that the terminal on the vehicle sends the traffic accident information to the server, and the server determines the distribution ran...

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
