Embodiment 1

[0031] In Embodiment 1 of the present invention, firstly, the processing flow of determining the path loss compensation factors for each adjacent cell by the base station and sending them to the user terminals belonging to it is described in detail, as shown in figure 2 As shown, it specifically includes the following steps:

[0032] S201. Establish a road traffic safety assessment model based on road traffic safety attributes using a factor analysis mathematical model, wherein the road traffic safety attributes include: driver attributes, vehicle attributes, road attributes, and environment attributes.

[0033] Furthermore, the road traffic system can be a dynamic system composed of various elements such as drivers, vehicles, roads, and the environment. In this system, unreliability, imbalance, and instability of any factor may lead to traffic conflicts, collisions, and traffic accidents. The following is a detailed analysis of the factors affecting traffic safety (mainly i...

Abstract

The embodiment of the invention provides a road traffic safety evaluating method and system. The method comprises: establishing a road traffic safety evaluating model by using a factor analysis mathematic model on the basis of a road traffic safety attribute; acquiring a road traffic safety attribute value corresponding to an appointed road segment in an appointed time segment; and analyzing the road traffic safety attribute value of the appointed road segment by using the road traffic safety evaluating model in order to obtain a road traffic safety evaluated result of the appointed road segment. The method and the system solves a problem that a static road traffic safety evaluated result in the prior art cannot reflect a road traffic safety status in real time. The invention relates to the technical field of computers.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a road traffic safety evaluation method and system. Background technique [0002] Cars have become a symbol of human civilization and progress. While enjoying the comfort and convenience brought by cars, human beings have also paid a heavy price. According to incomplete statistics, more than 700,000 people die from traffic accidents every year in the world today, and 20-25 million people are disabled. In the 20th century, more than 33 million people died under the wheels in the world. Traffic accidents have become an "endless war". The road traffic safety situation has become an issue that people pay more and more attention to. [0003] The evaluation methods of road traffic safety existing in the prior art include the following: [0004] The first one is the absolute number method. The absolute numbers of four indicators are used to evaluate road traffic safety, that is, ...
