Because of rail transit's fixed track,once the normal operation is interrupted due to unexpected events,a large number of passengers will be detained.The application of scheme for emergency feeder bus which include not only bus dispatching,but also the scheme of bus line operation is an efficient way to evacuate detained passenger when the rail transit is held up.To solve the problem of emergency feeder bus,it is suggested that the scheme of the bus dispatching and bus route layout be proposed on the basis of determining the affected passenger flow and analyzing the selection behavior of passengers.Based on the bus emergency reserve point,the transfer algorithm is proposed.An emergency bus route layout model is established,in which passengers who do not choose emergency bus connections are excluded,and corresponding connection schemes are designed.Finally,an example is given,and the result shows that considering passenger choice behavior will save scheduling cost,and the emergency bus transfer plan considering passenger choice behavior has certain practical significance.
