Research on Road-Side Safety Evaluation and Disposal Technologies of Mountainous Rural Highway

Abstract:

To reflect the real risk situation of mountainous rural highway and find out security risks, it is essential to ensure road safety with setting reasonable and effective security facilities in road-side dangerous sections. Based on SPA theory, establish the risk rating as the target layer and traffic characteristics, cross-section of the road, horizontal and vertical alignment as the criterion level, the Set Pair Analysis Model (SPAM) of mountainous rural highway road-side risk rating evaluation which contains ten key indicators realizes quantitative evaluation of risk rating on road-side risk. The model which is applied to practical engineering considers local materials as principle, proposes road-side protection facilities type and design parameters for different risk levels which is suitable for mountainous rural highway. Applications in Chengde mountainous rural highway show that evaluation results of SPAM model are objective and reasonable, it is a new method of comprehensive evaluation of the complex system for mountainous rural highway.
