Study on Extenics Evaluation of the Safety for Urban Road Intersections

Abstract:

On the basis of the theory and method of extenics and to evaluate the safety level of urban road intersections quantitatively, those are selected that infrastructure, signal lamp, conflict rate in all 3 categories of 9 indicators, meanwhile, the matter element model of safety evaluation for urban road intersections is put forward based on extenics, and the objective assessment with multiobjects for urban road intersections safety level is transformed into the single objective decision which is convenient to be estimated and compared. Then by calculating the comprehensive correlative degree it is analyzed that each index factor has influence on intersection safety. The results of numerical analysis shows that the extension method can much better evaluate intersection safety level for improving intersection safety to provide efficient and valued basis for traffic management department to make decision.
