Abstract
To study the problem of highway traffic safety in cold regions, a thorough statistical analysis using traffic accident historical data is used to evaluate the influencing factors on highway traffic safety. A road traffic safety indicator system for cold regions is developed to evaluate the weight of these influence factors, such as driver performance, vehicle capacity, road condition, and general impact of the traffic environment. An index system of highway traffic safety influencing factors for cold regions is developed, and an evaluation model for traffic road safety influencing factors in cold regions based on attribute recognition theory is proposed. The weight of the model is determined using an analytic hierarchy process combined with expert scoring. The evaluation model is based on single-index attribute measure values and multi-index comprehensive attribute measurement values, using the confidence criterion to identify the influence of road traffic safety factors on road traffic safety in cold regions. In addition, the fuzzy comprehensive evaluation method is used for comparative evaluation, and the evaluation results were consistent and verified the correctness and feasibility of the attribute recognition model. Results showed that the evaluation system was in good agreement with actual traffic conditions in cold regions.
Highlights
The rapid development of the economy in recent years has increased the quantity of motorized traffic on roads and served to enhance rapid developments in the transportation industry
The results provide a reliable and effective road traffic safety evaluation method that can be used for special environmental conditions in cold regions and reduce accident rates
The attribute recognition theory was developed on the basis of the fuzzy theory, and the ordered segmentation class is effectively identified according to confidence criterion
Summary
The rapid development of the economy in recent years has increased the quantity of motorized traffic on roads and served to enhance rapid developments in the transportation industry. The increasing number of motor vehicles and increased traffic flows have led to the construction of new roads. The scale, quantity, and scope of roads have been increasing, and the service quality has been continuously improved. Travel has become more convenient, fast, and comfortable. These improvements have brought many serious traffic safety problems and negative social impacts to the country. Road traffic accidents occur frequently, especially serious traffic accidents, resulting in casualties and property losses. The contradictions between people, vehicles, roads, and the environment are increasing
