　　A series of empirical studies are performed to demonstrate the application of this dissertation. The results show that an increased duration of activity participation may accompany an alteration of departure time or mode choice. The results also show that the use of dynamic information for travelers is related to induced activity participation and travelers’ socioeconomic characteristics. The results show that the important factors influencing travelers’ available duration vary as the travelers in different positions. The results show that travelers may not be hurry to modify their original decisions as they receive the incident information when there exists an improved convenience for transfer and with arrival time constraint. The results show that as travelers perceive more valid information at origin, they tend to adjust original decisions close to preplanned departure time. The result implies that traveler located during the trip focuses more on the effects of waiting time rather than other positions. The results show that the positions where travelers receive the information do affect traveler optimal timing for adjusting their pre-planned decisions. The researches findings are expected to help transportation planners better understand the traveler response behavior towards an incident. In sum, the results of the study provide a reference for transportation planners and transit providers to capture traveler dynamic choice behavior and to help better understand the nature and magnitude of the impact of dynamic information on activity participation and trip making behavior.
