考虑出行者选择偏好的出行方式选择模型

　　In order to analyze the regularity of traveler's route choice behavior under emergency incidents, the traveler's behavior decision-making model is established by introducing prospect theory. First, the accident dissipation time is analyzed, and the model of accident dissipation time is established. Then, the traveler's behavior decision-making process is analyzed, and the traveler's behavior decision-making frame is established. By applying prospect theory, the utility function for traveler's route choice is put forward in terms of traveler's earning and loss respectively, and the route utility is analysed by using continuous-discretion method. At last, the traveler's route choice model is established to describe traveler's behavior. A simulation case study is conducted under an assumption scene to research the bounded-rational traveler's route decision-making behavior and the influence of expect trip time on traffic accident dissipation time and route choice result. A comparative experiment is used to prove the consistence between the simulation result and experiment result, and the applicability of bounded rational decision-making in traveler's route choice area.
