摘　　要：通过建立基于诱导信息的路径选择决策模型,设计仿真实验并采用Matlab程序实现,研究结果发现:诱导信息对均衡交通流分配具有显著作用,且随着出行者对诱导信息的信任度增大,作用越大;管理者不论以系统最优还是用户均衡原则发布诱导信息都基本能实现其目标,且当出行者为完全信息型时,还能实现系统最优与用户均衡的协调﹒The traveler route choice decision-making model based on guiding information was established, the simulation experiments were designed, the matlab procedure was used to carry on the simulation, and the conclusions were drew as followings： （1） The guiding information has the remarkable function for balancing traffic distribution, moreover the function obviously increases along with the traveler＇s confidence to the guiding information increasing; （2） The governor＇s goal can be realized basically, whether the guiding information is issued by the principle of the system optimization or the user equilibrium,furthermore, if the travelers trust the guiding information completely, the coordination of the system optimization and the user equilibrium can be realized.

关 键 词：诱导信息 路径选择行为 交通流 系统最优 用户均衡
