Index Analysis of Traffic Operation Based on Information Entropy

In practise,traffic engineers will take on different indexes to analyse the traffic performance of a same spatiotemporal node.Different indexes describe the realization process of traffic operation from different profiles,and as the external features expressions of a same traffic operation phenomena,differences in the extent exist among the indexes.From the perspective of information theory,content of information of various indexes differs from each other.Therefore,information entropy is proposed to estimate the depicting degree of various indexes to traffic operation,whereafter,by determining and ordering the information entropy,it could be broadly applied into the filtration of indexes in different environments.
