This paper uses stated preference questionnaire survey method to collect intention data of metro passengers' travel behavior under failure situation in Suzhou and Shanghai, compares travel characteristics and behavioral intentions of the two cities' metro passengers, and analyzes significant factors affecting behavior selection and its impact trend. The results show that, travel time, travel frequency and safety awareness of Shanghai's metro passengers are significantly higher than those of Suzhou's passengers. Choice intentions of waiting, detouring or changing a station to leave of Shanghai's passengers are also slightly higher than those of Suzhou's passengers. Moreover, age and educational level influence the passengers' behavior selection obviously. This result can provide useful reference to optimize the adjustment plan of the metro network operation.
