Abstract

To evaluate emergency traffic warning, it is necessary to establish a set of accurate, concise, easy operation indexes system. Influence of unexpected events on transportation system is complex, involving many indexes, the early warning evaluation calculation is complex, and calculation accuracy is not high using all indexes. According to the characteristics of emergency nature and transportation system, the comprehensive index system was established including emergency coupling city traffic crisis alarm and warning, then the comprehensive index system was analyzed by clustering analysis of Matlab for the order of importance of each index, the main early warning index was screened out to establish the index system for evaluation calculation. Through the cluster analysis of Matlab, the initial index system including 31 indexes turned into the index system consists of only 16 main index, which helps to speed up the early warning evaluation speed, to improve the efficiency of emergency decision
