Abstract: In order to solve the problem that the influence of social information on route selection lacks quantitative analysis, based on the behavior experiment theory, the experiment of subject's route selection behavior is designed under the three scenarios of no traffic information, partial traffic information and complete traffic information, which are realized by z-Tree and z-leaf software. The experiment shows that: (1) in the state of no traffic information, the subjects are more inclined to choose the shortest possible path for decision-making; (2) in the state of partial traffic information, the subjects are more inclined to choose the optimal road section of the current node, and the path selection result is better than that in the situation of no information on the whole, but the specific situation is that the time-consuming of individual path selection increases; (3) in the state of complete traffic information, the overall and individual path The best choice.
