In this paper, Kriging Improved Response Surface Method (KIRSM) is extended to the reliability analysis of traveler, and used to study the reliability of traveler of Fanhegang Bridge. Selecting some sample points which are uniform distribution by the means of Latin Hypercube Sampling, and then fitting the response surface which is close to limit state equation quickly, and calculating the reliability finally. The results show that the KIRSM is feasible and effective, the traveler of Fanhegang Bridge possesses a high reliability.
