摘要
道路是城市的主要基础设施,正确、及时地对道路的路面状况作出评价,对保持交通畅通、确保交通安全、减少交通事故、充分发挥道路设施功能和效益等具有十分重要的现实意义.基于属性识别理论能对事物进行有效识别和比较分析的原理,建立了路面状况评价的属性识别模型,并运用熵值法确定指标权重,避免了定权的主观随意性,提高了评价模型的可信度.将该模型应用于路面状况的实例评价中,为路面状况评价提供了一种简单、适用的评价方法.
Roadway is the primary foundation establishment of a city. Exact and timely evaluation for pavement condition plays an important role in keeping traffic flowing and safe, reducing accident, and bringing into play the establish function of roadways. Base on the attribute recognition theory which makes effect identification and analysis for things, the attribute recognition model of evaluation for pavement condition is discussed, and the power weight is developed with the entropy method, which avoids the subjectivity and increases the reliability. This model introduced a simple and effective appraisal method of road pavement condition.
