Method of Evaluating Traffic Adaptability of Highway Network Based on Cloud Theory
Zhu Cong-kun · Highway Engineering · 2012
The fuzziness and randomness exist in traffic adaptability of highway network,but the present method only focuse on one aspect of them,which is obviously less scientific.The cloud theory based on the traditional fuzzy set theory and the probability theory can solve both of them at the same time.The process is simple,the maneuver ability is better.This paper studied how to apply the cloud theory to handle the fuzziness and randomness in traffic adaptability evaluation and give concrete appraisal step,it takes the highway network in Enshi Autonomous Prefecture of Hubei Province and Heilongjiang Province as the example to demonstrate how to apply the method,the results are consistent with the actual situation,compared with the traditional evaluation methods,the method proposed in this paper not only evaluates traffic adptability of highway network but also tests the information about the credibility of the evaluation result.
