At present, the urban rail transit (URT) system
has achieved network operation in many major cities of
China. But, little attention has been given to the vulnerability of the URT system. The purpose of this study is
to assign the passenger flow under the condition of section
interruption in URT system. Two surveys (a passenger
behavior survey and a stated preference survey) were
conducted and a multinomial logit model was developed.
The results show that although the first choice of passengers in emergency situation is to stay in URT system by a
circuitous way, more than half of the respondents express
interest in the temporary shuttle bus. For the temporary
shuttle bus, the sensitivity analysis show that the relative
speed is more important than crowding degree for passengers. The significant variables mostly fall in the personal attributes such as income, gender, age, etc. The
impacts of trip feature factors are similar to the previous
research in normal situations. These results provide basic
support for passenger flow assignment at the shuttle bus
level and reducing the risk of crowding at some special
stations. Moreover, it is also good for reducing passenger
delay and recovering the trip.
