A Decision-making Method for Risk Sections Safety Improvement of Minor Arterial Highway Network Based on Multi-objective Fuzzy Optimization Model
In order to ensure that decision-makers can reasonably improve the safety of risky road sections in the road network under limited resource conditions,by analyzing the factors that affect the safety improvement of risky road sections,fuzzy optimization methods and mathematical transformation methods are applied to transform the fuzzy judgment matrix provided by decision-makers into a relative superiority matrix that meets the consistency requirements.A multi-objective fuzzy optimization model suitable for safety improvement decision-making of high-risk sections in ordinary trunk highway networks has been established and solved.The model was applied to the safety improvement project of the ordinary trunk road network under the jurisdiction of Guizhou Duyun Highway Management Bureau,and good decision-making and application results were obtained.The results indicate that the fuzzy optimization model has reliability and effectiveness in the safety improvement decision-making of highway project groups.
