AI Technical Summary

Technical Problem

Existing technologies lack sophisticated assessments for highway traffic accidents in high-altitude areas, and cannot effectively account for the problems of untimely rescue caused by extreme geographical environments, physiological challenges, and weak logistical support, thus affecting emergency rescue capabilities.

Method used

Using a hypoxic and non-hypoxic medical model that integrates medical theory and statistical models, combined with the current injury index, altitude sickness index, and duration index, a linear regression model is used to fit the trend of injury deterioration and assess the severity of traffic accidents.

Benefits of technology

Accurately assessing the severity of traffic accidents provides a scientific basis for rescue resources for medical points and traffic command departments along plateau highways, thereby enhancing emergency rescue capabilities.

Abstract

The invention relates to the technical field of traffic safety, and discloses a high-altitude region road traffic accident influence assessment method. The evaluation method comprises the following steps: acquiring a current injury condition index and a current altitude stress index of a person in a current traffic accident and a current duration index of a rescue unit arriving at a traffic accident site; obtaining the hypoxia medical model after parameter updating; using the updated hypoxia medical model as a calculation framework, and determining a current hypoxia deterioration result index corresponding to the current injury condition index according to the current altitude stress index and the current duration index; and determining the severity of the current traffic accident according to the current hypoxia deterioration result index. By adopting the assessment method, the severity of the traffic accident can be accurately assessed. The invention further discloses a system for evaluating the influence of the highway traffic accidents in the high-altitude area.
