Abstract

The embodiment of the invention relates to the technical field of computers, in particular to a traffic safety risk level determination method, device and system. The method comprises the steps of obtaining traffic data of a target road section in a target time period, performing classification and / or statistical processing on the traffic data, obtaining at least two pieces of processed index data, and when no index data in the at least two pieces of index data is larger than a corresponding preset boundary threshold value, determining whether the index data is larger than the preset boundary threshold value based on all the index data and the traffic data. According to the method, the target risk score is determined, different indexes are fused according to a certain mode, the comprehensive risk score considering various indexes can be obtained, the reliability of a final result is ensured, and the traffic safety risk level is determined according to the target risk score and a preset level division rule. And through the fused comprehensive score, the determined risk level is more accurate, and the working efficiency is further improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technologies, and in particular, to a method, device, and system for determining a traffic safety risk level. Background technique [0002] The determination of the dynamic risk level of road traffic safety has important decision-making reference value for the timely early warning and control of traffic operation safety. Different risk sources have different impacts on traffic safety. [0003] In the prior art, in order to determine the dynamic risk level of road traffic safety, a certain type of data is usually collected, and then such data is processed to obtain the final dynamic risk level of road traffic safety. [0004] However, road traffic is a very complex system, which includes a variety of situations. Under the existing technology, the dynamic risk level of road traffic safety calculated based on a single index is usually very inaccurate, and the reference value provided is ...
