Abstract

Objective: Road accidents, especially on mountainous roads, pose significant traffic safety challenges that require accurate prediction and optimal management. In Iran, as a disaster-prone country, road accidents rank as the second-highest risk in terms of occurrence frequency, after earthquakes, highlighting the critical importance of road accidents as a significant risk factor. In this study, using data from the Red Crescent mission reports along with road, environmental, and traffic features, a deep learning transformer model was developed to identify accident-prone locations on the Chalous road corridor. This model extracted complex nonlinear patterns with considerable accuracy and predicted high-risk points categorized into three accident severity classes (fatal, injured, treated on site). Subsequently, using the Grey Wolf Optimizer algorithm, the optimal placement of rescue bases was performed to increase road coverage and reduce response time. Results showed that rescue coverage on the Chalous corridor increased from 22.77% to 86.91%, and average response time decreased from approximately 14 minutes 45 seconds to 8 minutes 22 seconds, representing a 64% improvement in coverage and a 43% reduction in reaction time, respectively. This study demonstrated that integrating real-world data, advanced deep learning models, and optimization algorithms provides an effective tool for improving rescue management, enhancing safety on high-traffic and high-risk corridors, and reducing injuries and fatalities. The findings can serve as a basis for designing intelligent crisis management systems and developing preventive programs in other regions of the country.
